The '''iMac''' is a series of [[All-in-one computer|all-in-one desktop computers]] designed, manufactured, and sold by [[Apple Inc.]] Between 2006 and 2022, the [[iMac|iMac series]] used chipsets based on [[Intel]] architecture. While sold, it was one of three desktop computers in the [[Mac (computer)|Mac]] lineup, serving as an all-in-one alternative to the [[Mac Mini]], and sat below the performance range [[Mac Pro]]. It was sold alongside a higher-end, [[Xeon]]-based [[iMac Pro]] from 2017 to 2021.

The earliest Intel iMacs reused the same white [[polycarbonate]] enclosure as the [[iMac G5]]. Later models shifted to [[aluminum]] and plastic, and then a unibody aluminum case. The iMacs released after October 2012 also featured a much thinner display, with the edge measuring just 5&nbsp;mm. This design would persist until the line was discontinued.

As part of the [[Mac transition to Apple silicon|Mac transition to Apple's own processors]], the Intel-based iMac was succeeded by the [[iMac (Apple silicon)|Apple silicon iMac]] beginning in 2021. Apple discontinued the 21.5-inch Intel iMac the same year, with the 27-inch model discontinued in March 2022, following the announcement of the [[Mac Studio]] and 27-inch [[Apple Studio Display]].<ref>{{Cite web |last=Hall |first=Zac |date=2022-03-08 |title=Goodbye, 27-inch iMac; hello Mac Studio and Studio Display — Apple discontinues all-in-one |url=https://9to5mac.com/2022/03/08/27-inch-imac-discontinued |access-date=2022-03-08 |website=9to5Mac |language=en-US |archive-date=March 8, 2022 |archive-url=https://web.archive.org/web/20220308200111/https://9to5mac.com/2022/03/08/27-inch-imac-discontinued |url-status=live}}</ref>

==Overview==
The iMac is an [[all-in-one computer|all-in-one personal computer]]. The machine has an integrated [[Liquid-crystal display]] (LCD), with the computer components integrated either behind the screen or below it in a "chin". An L-shaped aluminum foot allows the screen to be tilted but does not offer height adjustment. Ports for connecting peripherals are located on the bottom edge of the computer; an optical drive is located along the right edge of certain models. If wireless peripherals are used, the iMac's only cable is the power cord routed through the back.

On June 22, 2020, Apple's [[Apple Worldwide Developers Conference|Worldwide Developer Conference]] keynote included the announcement that future Macintosh computers would [[Mac transition to Apple silicon|transition]] yet again to Apple's own [[ARM architecture|ARM]]-based system-on-chips;<ref name=":4">{{Cite web|url=https://arstechnica.com/gadgets/2020/06/this-is-apples-roadmap-for-moving-the-first-macs-away-from-intel/|title=This is Apple's roadmap for moving the first Macs away from Intel|date=June 22, 2020|access-date=June 23, 2020|publisher=Ars Technica|archive-url=https://web.archive.org/web/20200623082629/https://arstechnica.com/gadgets/2020/06/this-is-apples-roadmap-for-moving-the-first-macs-away-from-intel/|archive-date=June 23, 2020}}</ref> in April 2021, Apple unveiled a [[iMac (Apple silicon)|redesigned iMac]] based on its [[Apple M1|M1 system-on-chip]].<ref name=":5">{{Cite web|last=Gonzalez|first=Oscar|title=New iMac comes with magnetic power plug that doubles as Ethernet cable|url=https://www.cnet.com/news/new-imac-comes-with-magnetic-power-plug-that-doubles-as-ethernet-cable/|access-date=2021-04-21|website=CNET|language=en|archive-date=April 20, 2021|archive-url=https://web.archive.org/web/20210420175900/https://www.cnet.com/news/new-imac-comes-with-magnetic-power-plug-that-doubles-as-ethernet-cable/|url-status=live}}</ref>

At the [[Macworld Conference and Expo]] on January 10, 2006, [[Steve Jobs]] announced that the new iMac would be the first [[Macintosh]] to use an [[Intel]] processors.

It also shipped at the same price points. The first Intel iMac featured an [[Intel Core Duo]] processor and [[PCI Express]] graphics processing units (GPUs). Like the iSight revision of the iMac G5, the machine was not designed to be user-serviced, and almost all components are difficult to access; the exception are the [[random-access memory]] slots, which are found on the bottom of the machine.<ref name="nytimes_2006-01-10"/><ref name="anandtech_2006-01-30">{{cite web|last=Lal Shimpi|first=Anand|date=January 30, 2006|url=https://www.anandtech.com/show/1936/2|title=Apple Makes the Switch: iMac G5 vs. iMac Core Duo|website=[[Anandtech]]|pages=1–15}}</ref><ref name="arstechnica_2006-01-17">{{cite web|last=Bangeman|first=Eric|date=January 17, 2006|url=https://arstechnica.com/gadgets/2006/01/imac-coreduo/|title=iMac 17" Core Duo|website=[[Ars Technica]]|access-date=August 25, 2024|pages=1–7}}</ref> One update from the iMac G5 was the addition of a [[Mini-DVI]] port that allowed for extending the computer contents to a second monitor versus mirroring the image.<ref name="pcmaguk_2006-01-19">{{cite web|author=Staff|date=January 19, 2006|url=https://www.pcmag.com/archive/apple-imac-intel-core-duo-169578|title=Apple iMac (Intel Core Duo)|website=[[PCMag]]|access-date=August 25, 2024}}</ref>

In early February 2006, [[Apple Inc.|Apple]] confirmed reports of video display problems on the new Intel-based iMacs. When playing video on Apple's [[Front Row (software)|Front Row]] media browser, some 20-inch iMacs (those built-to-order with upgraded video cards) showed random horizontal lines, ghosting, video tearing and other problems. The problem was fixed with a software update.{{cn|date=September 2024}}

An education-only model of the iMac shipped in July 2006 that replaced the [[eMac]] in Apple's lineup. This model came with a lower starting price, but had a smaller hard drive, integrated graphics processor, and a [[combo drive|combo optical drive]] rather than the [[SuperDrive]]s on other iMacs.<ref name="macworld_2006-07-23">{{cite web|last=Seff|first=Jonathan|date=July 23, 2006|url=https://www.macworld.com/article/180874/imacedrev.html|title=iMac Education Configuration|website=[[Macworld]]|access-date=August 25, 2024}}</ref> The entire iMac lineup was refreshed with a [[Core 2 Duo]] chip and a lower price in September 2006.<ref name="nytimes_2006-09-07">{{cite news|date=September 7, 2006|url=https://www.nytimes.com/2006/09/07/business/07apple.html|title=Apple Updates iMac Desktop Computers|work=[[The New York Times]]|access-date=August 25, 2024|page=C13}}</ref> Apple added a new 24-inch model with an [[IPS panel]] display and a resolution of 1920 × 1200 ([[WUXGA]]), making it the first iMac to be able to display [[1080p]] content in its full resolution, and a [[VESA]] [[Flat Display Mounting Interface]].{{cn|date=August 2024}}

In March 2009, Apple released a minor refresh of the iMac line. Changes included a fourth [[USB]] port, replacement of two [[FireWire 400]] ports with one [[FireWire 800]] port, replacement of [[mini-DVI]] with [[Mini DisplayPort]], and a slightly redesigned base which is vertically thinner. Otherwise, the exterior design is almost identical to the 2007 and 2008 models. The models were one 20-inch configuration and three 24-inch configurations (instead of two at each screen size as before).<ref>{{Cite web |url=https://support.apple.com/kb/SP507 |title=iMac (Early 2009) - Technical Specifications |access-date=July 7, 2023}}</ref>

Apple doubled the default RAM and hard-disk size on all models, moving the RAM to the DDR3<ref name="Mid 2007"/> specification.

=== Unibody (2009–2011)<span class="anchor" id="3rd generation: Unibody iMac"></span><span class="anchor" id="Unibody"></span> ===
[[File:Imac 16-9.png|thumb|27-inch Unibody iMac|250px]]
In October 2009, a 16:9 [[Display aspect ratio|aspect ratio]] screen was introduced in 21.5" and 27" models, replacing the 20" and 24" 16:10 aspect ratio screens of the previous aluminum models (a 24" iMac was brought back in 2021, albeit with a different aspect ratio). The back is made of aluminum instead of plastic, and is a continuation of the aluminum body from the front and sides. Video card options entirely switched to [[AMD]], except for the standard onboard [[Nvidia]] card in the base smaller model. The iMac's processor selection saw a significant increase.

The Intel i-series chips are introduced to Mac for the first time on the higher-spec 27-inch models.

Default [[RAM]] has also been increased across the iMac range. With the advent of the larger screens, Apple doubled the number of memory slots from two to four. Consequently, the maximum memory capacity was also doubled (to 16 [[gigabyte|GB]]),<ref>1&nbsp;GB = 1024{{Sup|3}} B</ref> and for Intel Core i-series (27-inch), quadrupled, to 32&nbsp;GB.

The 27-inch models of the line became the first to offer Target Display Mode, allowing the iMac to be used as an external display for another Mac computer when connected via [[Mini DisplayPort]], a feature that was extended to the 21.5-inch models onwards with the introduction of [[Thunderbolt (interface)|Thunderbolt]].

The Mid 2010 iMac 27" has AMD Radeon HD5650 and HD5750 graphic cards. Both cards cannot support the low-level [[Metal (API)|Metal API]], preventing this model from upgrading to Mojave and Catalina. AMD had developed a firmware upgrade that would allow both graphic cards to support Metal and Mid 2010 iMac to be upgraded to latest macOS, but Apple had refused to certify them.

The Late 2011 Unibody iMac is also the last model to include an internal [[SuperDrive]].

=== Slim Unibody (2012–2017)<span class="anchor" id="4th generation: Slim Unibody iMac"></span><span class="anchor" id="Slim Unibody"></span> ===
[[File:IMac Late 2012 Edge.jpg|thumb|27-inch Slim Unibody iMac]]
In October 2012, a new iMac model was introduced that featured a smaller body depth than the previous models, measuring 5&nbsp;mm at its thinnest point, and without an internal [[SuperDrive]]. This was partly achieved by using a process called Full Lamination. The display and glass are laminated together, eliminating a 2&nbsp;mm gap between them. The 21.5-in and 27-inch screens remained at their previous resolutions, 1920 × 1080 and 2560 × 1440 respectively.

As with the 2009 model, memory has been upgraded; the standard specification is now 8&nbsp;GB, with the 21.5-in model supporting up to 16&nbsp;GB and the 27-inch model supporting up to 32&nbsp;GB. It was reported that the 21.5&nbsp;in iMac would have non-replaceable soldered memory similar to the [[MacBook Air]] and [[MacBook Pro|Retina display MacBook Pro]]<ref>{{Cite web|url = http://bgr.com/2012/10/24/apple-imac-non-upgradable-ram/|title = Users can't upgrade the RAM in Apple's new 21.5-inch iMac|date = October 24, 2012|access-date = January 2, 2013|archive-date = January 2, 2013|archive-url = https://web.archive.org/web/20130102091142/http://bgr.com/2012/10/24/apple-imac-non-upgradable-ram/|url-status = live}}</ref> though tear-downs show that it uses removable memory but accessing the modules requires ungluing the screen and removing the motherboard.<ref>{{Cite web|url = http://www.ifixit.com/Teardown/iMac+Intel+21.5-Inch+EMC+2544+Teardown/11936/2|title = IMac Intel 21.5" EMC 2544 Teardown|date = December 2012|access-date = January 2, 2013|archive-date = January 26, 2013|archive-url = https://web.archive.org/web/20130126045101/http://www.ifixit.com/Teardown/iMac+Intel+21.5-Inch+EMC+2544+Teardown/11936/2|url-status = live}}</ref> The 27-inch version features an access port to upgrade memory without disassembling the display.<ref>{{Cite web |title=Upgrading RAM On The New 27-inch iMac Is Easy, Here's How {{!}} Cult of Mac |date=December 3, 2012 |url=http://www.cultofmac.com/204018/upgrading-ram-on-the-new-27-inch-imac-is-easy-heres-how |access-date=January 2, 2013 |archive-date=February 20, 2017 |archive-url=https://web.archive.org/web/20170220051853/http://www.cultofmac.com/204018/upgrading-ram-on-the-new-27-inch-imac-is-easy-heres-how |url-status=live}}</ref> Apple also upgraded the computers' processors, using Intel's [[Ivy Bridge (microarchitecture)|Ivy Bridge]] [[microarchitecture]]-based Core i5 and Core i7 microprocessors.

Video cards are now [[Nvidia]] as standard. USB 3.0 ports were included for the first time. The 2012 iMac also features the option of a [[Fusion Drive]] which combines an [[Solid-state drive|SSD]] and a conventional [[Hard disk drive|HDD]] to create more efficient and faster storage. Apple also removed the built-in optical drive starting with the 2012 model.

On March 5, 2013, Apple quietly announced an education-only version of the iMac, with less powerful specs for a cheaper price. It included a 3.3&nbsp;GHz dual-core Intel Core i3 processor, 4&nbsp;GB memory, a 500&nbsp;GB hard drive and Intel HD Graphics 4000, retailing for US$1,099, $200 cheaper than the base-level consumer iMac.<ref>{{Cite web |last=Slivka |first=Eric |date=March 5, 2013 |title=Apple Launches $1099 21.5-Inch iMac With 3.3&nbsp;GHz Dual-Core i3 Processor for Educational Institutions |url=http://www.macrumors.com/2013/03/05/apple-launches-1099-21-5-inch-imac-with-3-3-ghz-dual-core-i3-processor-for-educational-institutions |access-date=June 16, 2013 |archive-date=May 27, 2013 |archive-url=https://web.archive.org/web/20130527190337/http://www.macrumors.com/2013/03/05/apple-launches-1099-21-5-inch-imac-with-3-3-ghz-dual-core-i3-processor-for-educational-institutions |url-status=live}}</ref>

On September 24, 2013, the 2012 iMac model was updated with 4th-generation Intel [[Haswell (microarchitecture)|Haswell]] processors and Nvidia 7xx series GPU, promising up to 1.4× improvements in performance. It also has 802.11ac Wi-Fi, which is capable of reaching speeds up to 1300 [[megabit|Mbit]]/s<ref>1&nbsp;MBit = 1000{{Sup|2}} bit</ref> and PCIe-based flash storage, offering up to 1.5× the performance of previous Ivy Bridge unibody iMacs. This applies to both the Fusion Drive and pure-SSD options. These became the last iMacs to offer Target Display Mode, as the Retina line introduced the following year are incompatible with the feature due to resolution differences.

At [[WWDC]] on June 5, 2017, a refreshed model was added with [[Kaby Lake]] processors and Bluetooth 4.2 support. Apple retailed the 21.5-inch model until October 29, 2021. It was sold in a single stock configuration priced at $1,099 with a 2.3&nbsp;GHz dual-core 7th-generation Intel Core i5 processor. The machine was heavily criticized (more so towards the end of its production) for its lagging specifications, outdated design, and comparatively high price. The machine, however, was said to be popular among education shoppers.<ref>{{Cite web |title=Apple Discontinues Intel-Based 21.5-Inch iMac |url=https://www.macrumors.com/2021/10/30/apple-discontinues-intel-based-21-5-inch-imac |access-date=2021-10-30 |website=MacRumors |date=October 30, 2021 |language=en |archive-date=October 30, 2021 |archive-url=https://web.archive.org/web/20211030183352/https://www.macrumors.com/2021/10/30/apple-discontinues-intel-based-21-5-inch-imac |url-status=live}}</ref> It was the last Mac to have a [[Fusion Drive]] (albeit as an option), and after having them for 36 years, the last Mac to have a traditional hard drive. It was also the last Apple product not to have a Retina display.

[[File:IMac vector.svg|thumb|27-inch Retina iMac]]
A [[Retina Display]] "5K" model with a resolution of 5120 × 2880 was introduced alongside the previous year's models during a keynote on October 16, 2014. This 27-inch model was given faster Haswell processors and its two Thunderbolt ports were updated to Thunderbolt 2. Secondary storage was also upgraded to a 1&nbsp;TB<ref>1&nbsp;TB = 1000{{Sup|4}} B</ref> Fusion drive as standard and video options changed over to AMD Radeon R9 M290X and M295X.

In May 2015, a separate, affordable, budget counterpart of the 5K 27-inch iMac was announced with lower specifications. That same day the Late 2013 iMac lineup was completely discontinued. Later that year, a 21.5-inch "4K" model with a resolution of 4096 × 2304 was released on October 13, 2015, with older Broadwell processors, as the 27-inch counterparts were upgraded that day directly to Skylake ones. The new rechargeable and wireless peripherals were also introduced that day.

In 2017, both 21.5 and 27-inch iMacs were refreshed with Kaby Lake processors, DDR4 memories and upgraded AMD graphics with doubled or more graphic memories, Thunderbolt 3 (USB-C) ports, and Bluetooth 4.2. They were refreshed again in 2019 with [[Coffee Lake]] processors, including an 8-core build-to-order option, faster memory, and upgraded graphics including [[AMD Vega]] graphics as top of line build-to-order options.

On August 4, 2020, Apple refreshed the 27-inch 5K iMac with [[Comet Lake]] processors, AMD [[RDNA (microarchitecture)|RDNA]] architecture GPUs, the [[Apple T2|T2]] security chip, a 1080p [[FaceTime]] camera, [[Bluetooth 5]], improved speakers and microphones, and [[Solid state storage|solid state drives (SSD)]] standard. [[10 Gigabit Ethernet]] and nano-etched glass, similar to the [[Pro Display XDR]], are available as upgrade options. All models include non-replaceable, soldered SSDs, while models upgraded to 4&nbsp;TB and 8&nbsp;TB include an expansion bay for a second SSD. It was the last Mac with an Intel processor introduced by Apple, as well as the only Intel Mac introduced after the announcement of the [[Mac transition to Apple silicon]].<ref>{{Cite web |title=2020 iMac Teardown Reveals Internal Changes and Similarities |url=https://www.macrumors.com/2020/08/08/2020-imac-teardown |access-date=2020-08-08 |website=MacRumors |date=August 8, 2020 |language=en |archive-date=August 9, 2020 |archive-url=https://web.archive.org/web/20200809111058/https://www.macrumors.com/2020/08/08/2020-imac-teardown |url-status=live}}</ref>

The 2019 21.5-inch models remained available but received a minor configuration change with SSDs standard, with higher-capacity [[Fusion Drive]]s as a free build-to-order option, while [[hard disk drive]]s were no longer available.<ref>{{Cite web |last=Bohn |first=Dieter |date=2020-08-04 |title=Apple updates the iMac with new Intel processors and a better webcam |url=https://www.theverge.com/2020/8/4/21353899/apple-imac-2020-webcam-price-specs-release-date-announcement |access-date=2020-08-05 |website=The Verge |language=en |archive-date=October 10, 2022 |archive-url=https://web.archive.org/web/20221010174827/https://www.theverge.com/2020/8/4/21353899/apple-imac-2020-webcam-price-specs-release-date-announcement |url-status=live}}</ref> The 2020 refresh marked the end of hard disk drives in standard configuration [[Macintosh|Macs]], having been available in Macs since the [[Macintosh XL]] in 1985, as the 21.5-inch iMac was the only Mac still sold with them.<ref>{{Cite web |title=Apple's 21.5-inch iMac marks ditches mechanical hard drives for SSDs |url=https://appleinsider.com/articles/20/08/04/updated-215-inch-imac-loses-hard-drives-gains-256gb-ssd-base-configuration |access-date=2020-08-05 |website=AppleInsider |date=August 5, 2020 |language=en |archive-date=August 6, 2020 |archive-url=https://web.archive.org/web/20200806173228/https://appleinsider.com/articles/20/08/04/updated-215-inch-imac-loses-hard-drives-gains-256gb-ssd-base-configuration |url-status=live}}</ref> In March 2021, Apple silently removed the 512&nbsp;GB and 1&nbsp;TB SSD configurations for the 21.5-inch iMac.<ref>{{Cite web |title=Apple Discontinues 512&nbsp;GB and 1&nbsp;TB SSD Configurations of 4K 21.5-inch iMac |url=https://www.macrumors.com/2021/03/20/512gb-1tb-ssd-imac-21-discontinued |access-date=2021-03-26 |website=MacRumors |date=March 20, 2021 |language=en |archive-date=March 27, 2021 |archive-url=https://web.archive.org/web/20210327145108/https://www.macrumors.com/2021/03/20/512gb-1tb-ssd-imac-21-discontinued |url-status=live}}</ref>

The 21.5 inch iMac with 4K Retina Display was discontinued on April 20, 2021, after the announcement of the first Apple silicon-based iMac. The 27-inch model was discontinued on March 8, 2022, after the announcement of the [[Mac Studio]] and 27-inch [[Apple Studio Display]], and marked the end of Intel-based iMac models, and the return of the iMac to a single sized model since the introduction of 17" inch [[iMac G4]] in 2002.
