MacBook Pro

Apple refreshed the entire MacBook Pro line on October 24, 2006, to include Intel Core 2 Duo processors which was the first MacBook Pro model to be 64 bit.[9] Memory capacity was doubled for each model, to 1 GB on the low-end 15-inch and 2 GB for the high-end 15- and 17-inch models.[9] FireWire 800 was added to the 15-inch models. Hard drive capacity was increased, although video card options stayed the same.[9] The MacBook Pro line received a second update on June 5, 2007, with new Nvidia Geforce 8600M GT video cards and faster processor options.[12][13] LED backlighting was added to the 15-inch model's screen, and its weight was reduced from 5.6 pounds (2.5 kg) to 5.4 pounds (2.4 kg).[13] Furthermore, the speed of the front-side bus was increased from 667 MHz to 800 MHz. On November 1, 2007, Apple added the option of a 2.6 GHz Santa Rosa platform Core 2 Duo CPU as well as reconfigured hard drive options.[13]

First-generation 17-inch MacBook Pro

On February 26, 2008, the MacBook Pro line was updated once more.[14][15] LED backlighting was added as an option for the 17-inch model.[14] Processors were updated to "Penryn" cores, which are built on the 45 nanometer process (65 nanometer "Merom" cores were previously used), and hard drive and memory capacities were increased.[14] Multi-touch capabilities, first introduced with the MacBook Air earlier that year, were brought over to the MacBook Pro's trackpad.[14] When the 15-inch unibody MacBook Pro was introduced on October 14, 2008, the pre-unibody model with the same screen size was discontinued, while the 17-inch pre-unibody model continued to be sold.[16] The original case design was discontinued on January 6, 2009, when the 17-inch MacBook Pro was also updated with unibody construction.[17]

Some reviewers applauded the MacBook Pro for its doubling or tripling the speed of the PowerBook G4 in some areas.[4] For example, the 3D rendering program Cinema 4D XL was 3.3 times as fast (2.3 times faster),[4] and its boot-up time was more than twice as quick.[5] The MacBook Pro generally outperformed the PowerBook G4 in performance analyzer utility tests XBench and Cinebench.[5] Reviewers lauded the screen's maximum brightness, 67 percent brighter than the PowerBook G4; the excellent horizontal viewing angles; the matte options; and the bright, crisp, and true colors.[6] Although the screen offered fewer vertical pixels (1440 × 900 in the MacBook Pro instead of 1440 × 960 in the PowerBook), one reviewer called the screen "nothing less than stellar".[5] Reviewers praised the new MagSafe power adapter,[4] although one reviewer said it disconnected too easily in some instances.[5] They also praised the backlit keyboard, large trackpad, and virtually silent operation of the machine.[4][6] The new laptop also offered better wireless performance.

One reviewer criticized the decision to underclock the ATI Mobility Radeon X1600 graphics card by about 30 percent its original speed.[6] The notebook was also noted for running hot.[4][6] Users complained that upgrading system memory was harder than in older Apple notebooks.[5] Since the dimensions for the 15-inch MacBook Pro were tweaked slightly from the 15-inch PowerBook G4, older accessories such as notebook sleeves did not work with the new models.[5] Some users noted a slight flickering when the screen was on lower brightness settings.[5] Apple increased the battery capacity by 10 Wh, going from 50 in the PowerBook G4 to 60,[5] but the more powerful Core Duo CPU required more power.[5] Battery life therefore remained about the same as in previous models, at three-plus hours.[5]

The unibody-construction MacBook Pro largely follows the styling of the original aluminum iMac and the MacBook Air and is slightly thinner than its predecessor, albeit wider and deeper due to the widescreen display.[29] The screen is high-gloss, covered by an edge-to-edge reflective glass finish, while an anti-glare matte option is available in the 15- and 17-inch models in which the glass panel is removed.[33] The entire trackpad is usable and acts as a clickable button.[33] The trackpad is also larger than that of the first generation, giving more room for scrolling and multi-touch gestures.[33] When the line was updated in April 2010, inertial scrolling was added, making the scrolling experience much like that of the iPhone and iPad.[34][35][36] The keys, which are still backlit, are now identical to those of Apple's now-standard sunken keyboard with separated black keys.[34] The physical screen release latch from the previous generation is replaced with a magnetic one.

A size comparison of the unibody line of MacBook Pro laptops

During the MacWorld Expo keynote on January 6, 2009, Phil Schiller announced a 17-inch MacBook Pro with unibody construction. This version diverged from its 15-inch sibling with an anti-glare "matte" screen option (with the glossy finish standard) and a non user-removable lithium polymer battery.[37] Instead of traditional round cells inside the casing, the lithium-ion polymer batteries are shaped and fitted into each laptop to maximally utilize space. Adaptive charging, which uses a chip to optimize the charge flow to reduce wear and tear, extends the battery's overall life.[37] Battery life for the 17-inch version is quoted at eight hours, with 80 percent of this charge remaining after 1,000 charge-discharge cycles.[37]

At Apple's Worldwide Developers Conference (WWDC) on June 8, 2009, it was announced that the 13-inch unibody MacBook would be upgraded and re-branded as a MacBook Pro,[38] leaving only the white polycarbonate MacBook in the MacBook line.[39] It was also announced that the entire MacBook Pro line would use the non user-removable battery first introduced in the 17-inch MacBook Pro.[40] The updated MacBook Pro 13- and the 15-inch would each have up to a claimed seven hours of battery life, while the 17-inch would keep its eight-hour capacity.[38][40] Some sources even reported up to eight hours of battery life for the 13- and 15-inch MacBook Pros during casual use,[41] while others reported around six hours.[33] Like the 17-inch MacBook Pro, Apple claims that they will last around 1,000 charge cycles while still containing 80 percent of their capacity.[42] Graphics card options stayed the same from the previous release, although the 13-inch[43] and the base model 15-inch, came with only the GeForce 9400M GPU.[44] The screens were also improved, gaining a claimed 60 percent greater color gamut.[43][44] All of these mid-2009 models also included a FireWire 800 port and all except the 17-inch models would receive an SD card slot.[30] The 17-inch model would retain its ExpressCard/34 slot.[40] For the 13-inch MacBook Pro, the Kensington lock slot was moved to the right side of the chassis.[45] In August 2009, Apple extended the "matte" anti-glare display option to the 15-inch MacBook Pro.[46]

On April 13, 2010,[47] Intel Core i5 and Core i7 CPUs were introduced in the 15- and 17-inch models, while the 13-inch retained the Core 2 Duo with a speed increase.[47] The power brick was redesigned[34] and a high-resolution display (of 1680 × 1050) was announced as an option for the 15-inch models.[35] The 13-inch gained an integrated Nvidia GeForce 320M graphics processing unit (GPU) with 256 MB of shared memory, while the 15- and 17-inch models were upgraded to the GeForce GT 330M, with either 256 or 512 MB of dedicated memory.[47] The 15- and 17-inch models also have an integrated Intel GPU that is built into the Core i5 and i7 processors.[47] The 15-inch model also gained 0.1 pounds (0.045 kg).[35] Save for a third USB 2.0 slot, all the ports on the 17-inch MacBook Pro are the same in type and number as on the 15-inch version.[48] All models come with 4 GB of system memory that is upgradeable to 8 GB.[47] Battery life was also extended further in this update, to an estimated ten hours for the 13-inch and 8–9 hours on the 15- and 17-inch MacBook Pros.[47] This was achieved through both greater power efficiency and adding more battery capacity.[47] One reviewer reported about six hours of battery life through a continuous video battery stress test in the 15-inch[36] and another, who called the battery life "unbeatable", reported nearer to eight in the 13-inch through their "highly demanding battery drain test".[34]

Thunderbolt technology, Sandy Bridge dual core Intel Core i5 and i7 (on the 13-inch model) or quad-core i7 (on the 15- and 17-inch models) processors, and a high definition FaceTime camera were added on February 24, 2011. Intel HD Graphics 3000 come integrated with the CPU, while the 15- and 17-inch models also utilize AMD Radeon HD 6490M and Radeon HD 6750M graphics cards. Later editions of these models, following the release of OS X Lion, replaced the dashboard (F4) key with a launchpad key. The chassis bottoms are also engraved differently from the 2010 models.[49] The Thunderbolt serial bus platform can achieve speeds of up to 10 Gbit/s,[50] which is up to twice as fast as the USB 3.0 specification, 20 times faster than the USB 2.0 specification, and up to 12 times faster than FireWire 800.[51] Apple says that Thunderbolt can be used to drive displays or to transfer large quantities of data in a short amount of time.[51]

On June 11, 2012, Apple showcased its upgraded Mac notebooks, OS X Mountain Lion, and iOS 6 at the Worldwide Developers Conference (WWDC) in San Francisco.[52] The new MacBook Pro models were updated with Ivy Bridge processors and USB 3.0 ports, and the default RAM on premium models was increased to 8 GB.[53] Following this announcement, the 17-inch model was discontinued. After a media event on October 22, 2013, Apple discontinued all second-generation MacBook Pros except for the entry-level 2.5 GHz 13-inch model.[54] Apple discontinued the 13-inch second-generation MacBook Pro on October 27, 2016. Prior to its discontinuation it was Apple's only product to still include an optical drive and a FireWire port, and only laptop with a hard disk drive and Ethernet port.[55]

Some reviewers praised the new laptop's performance and compact size,[31] the quality of the screen, and sturdy unibody build,[31] which allowed easier upgrading of internal components as compared to the original models.[31] Some reviewers also noted that the new MacBook Pro ran more quietly and at cooler temperatures than first-generation machines.[31] Others, however, criticized the amount of heat generated by the new design.[56][57]

The Reviewers lamented the loss of a matte screen option for the 2008 unibody MacBook Pro, noting the reflectiveness of the screen in sunlight, even when its brightness was turned all the way up.[31] CNET's Dan Ackerman commented of the mid-2009 models: "According to Apple, the new display offers a wider color gamut, and the screen certainly looks bright and colorful, but we wish the same matte-screen option offered on the 17-inch MacBook Pro was available across the line... While the LED screen means a thinner lid and some battery life benefits, the edge-to-edge glass covering the entire display panel grabs stray light rays with ease, making the glossy screen hard to see in some lighting conditions."[33] By 2011, matte screens were offered for both the 15" and 17" models. Furthermore, the addition of Mini DisplayPort instead of the more popular HDMI was criticized.[31] The relatively low number of ports and lower end technical specifications when compared to similarly priced laptops from other brands were also bemoaned.[31]

Laptop Magazine's Michael Prospero praised the 2010 15-inch model's display, calling it "bright and crisp". He further commented, "While reflections from the glossy display weren't overwhelming, it's also nice to know there's an antiglare option—though only for the higher resolution display. Still, colors were bright, blacks were deep and dark, and viewing angles were excellent both vertically and horizontally." He also lauded the quality of the iSight webcam, the responsiveness of the touchpad, the microphone and speakers, as well as the performance of the new CPUs for the 15" model and the long battery life. Complaints included the price of the laptop, the low number of USB ports, and the lack of HDMI.[35]

CNET praised the automatic graphics switching features of the 15- and 17-inch 2010 models as well as the graphics cards themselves. Acclaim was also given to the Core i5 and i7 CPUs, the multi-touch trackpad, and the addition of audio capabilities to the Mini DisplayPort video output.[36] They also called for the addition of HDMI and the Blu-ray optical disc format, saying that most other computers in the MacBook Pro's price range possessed these features.[36] CNET also criticized the option of a higher-resolution screen in the 15-inch model, saying that "the higher-resolution screen should be included by default."[36]

Since the RAM and the hard drive on some generations of MacBook Pro are user-serviceable parts, there are aftermarket modifications to enhance the system with up to 16GB of DDR3-1600 RAM (although maximum capacity and frequency depend on the hardware in question), 7200-rpm hard drives or third-party SSDs.

Early and Late 2011 models with a GPU; 15" & 17"; reportedly suffer from manufacturing problems leading to overheating, graphical problem, and eventually complete GPU and logic board failure. A similar but nonidentical problem affected iMac GPUs which were later recalled by Apple.[90] The problem was covered by many articles in Mac-focused magazines, starting late 2013 throughout 2014.[91][92][93][94][95] In August 2014 the law firm Whitfield Bryson & Mason LLP had begun investigating the problem to determine if any legal claim exists.[96] On October 28, 2014, the firm announced that it has filed a class-action lawsuit in a California federal court against Apple. The lawsuit will cover residents residing in both California and Florida who have purchased a 2011 MacBook Pro notebook with an AMD graphics card. The firm is also investigating similar cases across the United States.[97] On February 20, 2015, Apple instituted the "MacBook Pro Repair Extension Program for Video Issues". This "will repair affected MacBook Pro systems, free of charge". The program covered affected MacBook Pro models until December 31, 2016 or four years from original date of sale.[98]

The third-generation MacBook Pro largely follows the design of the previous generation with its aluminum enclosure and separated black keys. The most apparent body changes are a thinner chassis and a display with a redesigned hinge and thinner bezel, and the removal of the internal optical drive and the battery indicator button and light on the side of the chassis. The power button is moved from the upper right corner of the chassis onto the keyboard, taking the place of the optical disc eject button.[119] At 0.71 inches (18 mm) thick, the 15-inch model is 25 percent thinner than its predecessor. The model name is no longer placed at the bottom of the screen bezel; instead, it is found on the underside of the chassis, similar to an iOS device. It is the first Macintosh laptop to not have its model name visible during normal use, as every prior laptop had its model name on the screen bezel or keyboard.[120]

The third-generation MacBook Pro received positive reviews of the Retina Display, flash storage and power. It was criticized, however, for its high price and lack of an Ethernet port and optical drive. Roman Loyola of Macworld said that the Retina MacBook Pro was "groundbreaking" and made people "rethink how they use technology". He praised the inclusion of USB 3.0 and the slimmer body.[121] Dan Ackerman of CNET commented "I've previously called the 15-inch MacBook Pro one of the most universally useful all-around laptops you can buy. This new version adds to that with HDMI, faster ports, and more portability. But it also subtracts from that with its exclusion of an optical drive and Ethernet port, plus its very high starting price. The Pro and Retina Pro are clearly two laptops designed for two different users, and with the exception of all-day commuters who need something closer to a MacBook Air or ultrabook, one of the two branches of the MacBook Pro family tree is still probably the most universally useful laptop you can buy."[122]

The Retina MacBook line has no internal optical drives. External drives such as Apple's SuperDrive (pictured) must be used instead.

Joel Santo Domingo of PC Magazine gave the MacBook Pro an "Editor's Choice" rating. He praised its "brilliant Retina display", the thin design, port selection and speedy storage, and highlighted the expandability via Thunderbolt ports which support up to seven devices each.[123] David Pogue of The New York Times praised the 15-inch model's screen, keyboard, sound, start-up time, cosmetics, battery life, storage, and RAM capacity. They criticized the lack of a SuperDrive, pricing, and the MagSafe 2 power connector's lack of backwards compatibility with the older MagSafe design.[124]

The Retina Display on the MacBook Pro have been criticized for "image retention", specifically for displays manufactured by LG.[125][126]

In 2017, one year after the introduction of the fourth generation of the MacBook Pro, the original lead developer of Tumblr Marco Arment wrote an evocative article in which he declared the third-generation MacBook Pro the best laptop ever made.[127] The sentiment was shared by many users of various social platforms.[128]

Apple was criticized for gluing the battery into the case, making it harder to be recycled (ease of disassembly is an EPEAT criterion). Greenpeace spokesman Casey Harrell said Apple "has pitted design against the environment—and chosen design. They're making a big bet that people don't care, but recycling is a big issue."[129] Wired also criticized Apple's recyclability claims: "[t]he design may well be comprised of 'highly recyclable aluminum and glass'—but my friends in the electronics recycling industry tell me they have no way of recycling aluminum that has glass glued to it like Apple did with both this machine and the recent iPad."[130]

In June 2019, Apple announced a worldwide recall for certain 2015 15" MacBook Pros due to a potential overheating and fire-safety risk. Affected units were sold primarily between September 2015 and February 2017 and recall eligibility is determined by the product serial number. It was determined that 432,000 units were affected with reports of minor burns, smoke inhalation and property damage. The company asked customers to stop using their MacBook Pros until they could be repaired with replacement batteries.[131][132][133]

In September 2019, India's Directorate General of Civil Aviation said MacBook Pros could dangerously overheat, leading the national carrier Air India to ban the model on its flights.[134]

The fourth-generation MacBook Pro follows the design of the previous two generations with an all-metal unibody enclosure and separated black keys. A few apparent design changes are a thinner chassis, thinner screen bezel, larger trackpad, the OLED Touch Bar, and shallower butterfly mechanism keyboard with less key separation than the previous models. The speakers grilles have been relocated to the sides of the keyboard on the 13-inch variant. Tear downs show that the speaker grilles on the 13-inch model with Touch Bar are "largely cosmetic", and that sound output mostly comes through the side vents.[166] The fourth-generation MacBook Pro comes in two finishes, the traditional silver color and a darker "space gray" color. The MacBook Pro model name returns to the bottom of the screen bezel in Apple's San Francisco font after being absent from the third generation. As with the Retina MacBook, the new models replace the backlit white Apple logo on the rear of the screen, a feature dating back to the 1999 PowerBook G3, with a glossy black opaque version.[167]

MagSafe, a magnetic charging connector, has been replaced with USB-C charging.[150] Unlike MagSafe, which provided an indicator light within the user's field of view to indicate the device's charging status, the USB-C charger has no visual indicator. Instead, the MacBook Pro emits a chime when connected to power.[150] The Macintosh startup chime that has been used since the first Macintosh in 1984 is now disabled by default. The laptop now boots automatically when the lid is opened.[150]

The battery life of the new models also received mixed reception, with outlets reporting inconsistent battery life and inaccurate estimates of time remaining on battery by the operating system. Apple addressed the latter by hiding the display of estimated battery time remaining entirely in a macOS update.[168][169] Consumer Reports did not initially recommend the 2016 MacBook Pro models, citing inconsistent and unpredictable battery life in its lab testing (which involves the consecutive loading of multiple websites). However, Apple and Consumer Reports found that the results had been affected by a bug caused by disabling caching in Safari's developer tools. Consumer Reports performed the tests again with a patched macOS, and retracted its original assessment.[170][171]

iFixit gave the models a score of 1 out of 10 for repairability, noting that memory, the processor, and flash storage are soldered to the logic board, while the battery is glued to the case. The entire assembly uses proprietary pentalobe screws and cannot be disassembled with standard tools.[158]

A report by AppleInsider has claimed that the updated butterfly keyboard fails twice as often as previous models, often due to particles stuck beneath the keys.[172] Repairs for stuck keys have been estimated to cost more than $700.[173] In May 2018, two class action lawsuits were filed against Apple regarding the keyboard problem with one alleging a "constant threat of nonresponsive keys and accompanying keyboard failure" and accusing Apple of not alerting consumers to the problem.[174][175] In June 2018, Apple announced a Service Program to "service eligible MacBook and MacBook Pro keyboards, free of charge".[176] The 2018 models added a membrane underneath keys to prevent malfunction from dust.[177] As of early 2019, there were reports of problems with the same type of keyboards in the 2018 MacBook Air.[178][179] In May 2019 Apple modified the keyboard for the fourth time and promised that any MacBook keyboard with butterfly switches will be repaired or replaced free during four years after the date of sale.[180]

Thermal throttling drew widespread attention when YouTuber Dave Lee posted a video of a MacBook Pro running Adobe Premiere that was throttled below the CPU's 2.9 GHz base clock speed.[181]

PC Magazine said "the Core i9 processor Apple chose to use inside the MacBook Pro (i9-8950K) has a base clock frequency of 2.9GHz, which is capable of bursting up to 4.8GHz when necessary. However, testing carried out by YouTuber Dave Lee showed that the Core i9 couldn't even maintain 2.9GHz, let alone 4.8GHz. And it ended up running at 2.2GHz due to the heat generated inside the chassis forcing it to throttle. Lee found the 2018 i9 MacBook Pro was slower than the 2017 MacBook Pro and stated, "This isn't a problem with Intel's Core i9, it's Apple's thermal solution."[182] When Lee put the i9 MacBook Pro inside a freezer, the render times were over 8 minutes shorter.[183]

On July 24, 2018, Apple released a software fix for the new 2018 MacBook Pros which addressed the thermal throttling problem. Apple said "there is a missing digital key in the firmware that impacts the thermal management system and could drive clock speeds down under heavy thermal loads on the new MacBook Pro".[184]

A "limited number" of 13-inch MacBook Pro units without Touch Bar, manufactured between October 2016 and October 2017, saw the built-in battery swell. Apple created a free replacement program for eligible units.[185]

A "limited number" of 128GB and 256GB solid-state drives used in 13-inch MacBook Pro (non-Touch Bar) units can lose data and fail. 13-inch MacBook Pro units with affected drives were sold between June 2017 and June 2018. This resulted in Apple launching a repair program for those affected – the repair involves the update of firmware.[186]

Some users are reporting kernel panics on 2018 models, because of the T2 chip. Apple is already aware of the problem and performing an investigation.[187] There are also user reports about the speaker crackling problems on the 2018 models.[188]

Users have reported malfunctioning display cables, causing uneven lighting at the bottom of the screen and ultimately display failure. The problem has been tracked to a cable, stressed from opening and closing the laptop. The entire display needs to be replaced in affected units.[189] In May 2019 Apple initiated a program to replace the display on affected 13-inch models made in 2016 for free, and the cable on the 2018 models and onwards was made 2 mm longer than on prior models.[190] Apple has been criticized for not extending the replacement program to the 15-inch models which are also affected by this issue.[191]

The 2016 MacBook Pro was criticised for needing hubs or dongles, shown, to connect with USB or SD cards.

The fourth-generation MacBook Pro received mixed reviews. The display, build quality, and audio quality were praised but many complaints went toward the keyboard butterfly switch, the touch bar not being useful in many applications due to a lack of development for it, and the lack of any USB-A ports, HDMI port or an SD card slot.

Ars Technica noted that the second-generation keyboard with firm keys was a "drastic departure" from previous Retina MacBook keyboards. It further noted that resting palms may brush the trackpad occasionally causing inadvertent cursor jumps onscreen as the laptop interprets this as input, without one's hands or wrists actually resting on it.[150] Also noted was an increase of bandwidth and approximately 40 percent increased read speed of the flash storage.[150] Engadget praised the thinner, lighter design, improved display and audio, and increased speed of the graphics and flash storage, but criticized the lack of ports and price.[192] Wired praised the display, calling it "the best laptop display I've ever seen", as well as praising the Touch Bar, though it criticized the need of adapters for many common connectors.[193] Likewise, The Verge concluded that "using [the new MacBook] is alienating to anyone living in the present. I agree with Apple's vision of the future. I'm just not buying it today."[194]

Engadget voiced their concerns that "by doing things like removing full-sized USB ports, the memory card reader and even the Function row, Apple seems to have forgotten how many of us actually work".[195] Heavy keyboard users criticized the Touch Bar, noting that command-line tools like Vim rely on keyboard usage, and the Touch Bar does not provide the tactile feedback necessary for "blind" usage of Function keys.[196] Miriam Nielsen from The Verge said about the Touch Bar experience: "When I tried to intentionally use the Touch Bar, I felt like a kid learning how to type again. I had to keep looking down at the bar instead of looking at the images I was actually trying to edit."[197] She also pointed out that after learning the Touch Bar one cannot work as efficiently on any other computer. Developers have their share of headaches because they cannot rely on the Touch Bar being present on every machine that runs their software. Even if Apple makes the Touch Bar an integral part of macOS, it will take "many years" for it to become ubiquitous, in the meantime anything in the Bar needs to be available through another part of the interface.[198]

Other items of critique were non-compatibility between Thunderbolt 2 and 3 devices, frequently unpleasant fan whine noises in idle CPU states on the larger screen (15") models were reported, where the two integrated fans run all the time by default. The coprocessor powering the touch bar and higher TDP of the stronger CPU models are responsible for this behavior.

YouTube tech reviewer Dave Lee was very critical of the high price of the MacBook Pro. He ultimately said that "for most people, [the MacBook Pro] is just way too expensive and overpriced."[199]

Reception to the 16-inch MacBook Pro was generally positive. Laptop Mag called the keyboard "much-improved".[252] The Verge praised the new keyboard, microphones, and speakers, but criticized the lack of peripherals such as an SD card slot.[253] 9to5Mac criticized the use of a 720p webcam and older 802.11ac Wi-Fi standard, noting that Apple's iPhone 11 family included a 4K front-facing camera and faster Wi-Fi 6.[254] MacWorld also noted the lack of Face ID.[255]
