TheiMac is a series ofall-in-one computers fromApple Inc., sold as part of the company'sMac family of computers. First introduced in 1998, it has remained a primary part of Apple's consumer desktop offerings since and evolved through seven distinct forms. The iMac natively runs themacOS operating system.
In its original form, theiMac G3 had agumdrop,ADM-3 oregg-shaped look, with aCRT monitor, mainly enclosed by a colored,translucent plastic case. The computer was, at the time, an inexpensive, consumer-oriented computer that would easily connect to theInternet. The second major revision, theiMac G4, moved a design with a hemispherical base containing all the main components and anLCD monitor on a freely moving arm attached to it. The third and fourth revisions, theiMac G5 and theIntel iMac, placed all the components immediately behind the display in a plastic casing, creating a slim unified design that tilts only up and down on a simple metal base. The fifth, sixth and seventh revisions swapped the plastic enclosure for metal and became progressively thinner over each revision.
The design of the iMac has been seen as both controversial and trendsetting. From its introduction, the computer has eschewed many entrenched legacy technologies, notably becoming an early adopter of theUSB port, and removingfloppy disk and lateroptical disc drives. The most recent revision, theApple Silicon iMac, uses Apple's own processors (silicon) and is 11.5 millimeters (0.45 in) thick. Between 2017 and 2021, Apple also sold a workstation-class version of the computer called theiMac Pro.
Apple was facing bankruptcy in the mid-1990s, with its market share cannibalized by Windows-based PCs and Macintosh clones. The company had tried and failed to ship a modern operating system for its hardware. Looking instead for an outside product to acquire, Apple announced its purchase ofNexT, Inc. in 1996. Alongside Next's products and software cameSteve Jobs, Apple's co-founder who had been ousted from the company years earlier. Jobs initially was brought on at Apple as an adviser, but Jobs replacedGil Amelio as interim CEO in 1997 and began a reorganization of the company. He reduced Apple's multitude of confusing computer options to just four: one laptop and one desktop model for consumers, and another laptop and desktop model for professionals. What became the iMac began as Apple's effort to develop the consumer desktop to fill that product gap.[citation needed]
Apple's head of designJony Ive and the rest of the design team developed sketches for a distinctive,all-in-one computer that was to be alegacy-free PC focused on ease of use and internet connectivity. The design team made the new computer colorful and translucent, built around a cathode-ray tube display wrapped in a curved plastic case. Ad agency directorKen Segall suggested the "iMac" name: it was short, had "Mac" in it, and the "i" prefix suggested the internet. Jobs initially hated it, but the name ultimately stuck.[1]: 109–110 Apple lateradopted the 'i' prefix across its consumer hardware and software lines, such asiPod,iBook (later MacBook),iPhone,iPad and various pieces of software such as theiLife,iCloud suite andiWork and the company's media player/store,iTunes.[citation needed]
Despite mixed reviews from the tech press, the iMac was a major commercial success at a time when Apple desperately needed a hit product.[2] The iMac ultimately sold more than six million units, being revised multiple times and appearing in 13 different colors and patterns.[citation needed] The iMac was "designed to make it easy for home users to connect to the Internet."[3] A commercial, dubbed "Simplicity Shootout", pitted seven-year-old Johann Thomas and hisborder collie Brodie, with an iMac, against Adam Taggart, aStanford UniversityMBA student, with anHP Pavilion 8250, in a race to set up their computers. Johann and Brodie finished in 8 minutes and 15 seconds,[4] whereas Adam was still working on it by the end of the commercial.
As the prices of flat screenliquid-crystal displays (LCDs) began to fall, Apple conceived of an update to the iMac. Inspired by a sunflower, theiMac G4 put the computer in a semi-hemispherical base, with the display sitting above it on a stainless steel arm. The arm allowed the display to be easily tilted, rotated, and raised and lowered by a touch. The exuberant colors of the old iMac were replaced by stark white.[citation needed]
Ever-increasing screen sizes led Apple to make theiMac G5 a more conservative design, with the components of the computer attached to the back of the display and raised above the resting surface with an aluminum foot.[citation needed]
By 2005, it had become more and more apparent that IBM's development for the desktop implementation of PowerPC was grinding to a halt. Apple announced at theWorldwide Developers Conference that it would beswitching the Macintosh to the x86 architecture and Intel's line of Core processors. The first Intel-equipped Macs were unveiled on January 10, 2006: the MacBook Pro and a new iMac, which outwardly looked identical to the iMac G5. Within nine months, Apple had smoothly transitioned the entire Macintosh line to Intel. The Intel-based iMac was redesigned in 2007 with an aluminum enclosure, which was gradually refined and slimmed down in the following years. In 2014, the iMac added high-resolution "Retina" 4K and 5K displays, and a more powerful, professional-oriented model, theiMac Pro, was introduced in 2017.
Apple announced a shiftfrom Intel processors to its own Apple silicon in June 2020. Apple announced redesigned iMacs with a 24-inch display andApple M1 chip in April 2021. These new models harkened back to the colorful iMac G3s, coming in seven colors. The iMac was updated in 2023 to use theApple M3 chip.[5] To date the company has stated there will not be a 27-inch M-series iMac.[6]
Theoriginal iMac was the firstlegacy-free PC.[7] It was the first Macintosh computer to have aUSB port but nofloppy disk drive. Subsequently, all Macs have included USB. Via the USB port, hardware makers could make products compatible with both x86 PCs and Macs. Previously, Macintosh users had to seek out certain hardware, such as keyboards and mice specifically tailored for the "old world" Mac's uniqueADB interface and printers and modems withMiniDIN-8 serial ports. Only a limited number of models from certain manufacturers were made with these interfaces and often came at a premium price. USB, being cross-platform, has allowed Macintosh users to select from a large selection of devices marketed for theWintel PC platform, such ashubs,scanners,storage devices,USB flash drives, andmice. After the iMac, Apple continued to remove older peripheral interfaces and floppy drives from the rest of its product line.
Borrowing from the 1997Twentieth Anniversary Macintosh, the various LCD-based iMac designs continued theall-in-one concept first envisioned in Apple's original Macintosh computer. The successful iMac allowed Apple to continue targeting thePower Macintosh line at the high-end of the market. This foreshadowed a similar strategy in the notebook market when the iMac-likeiBook was released in 1999. Since then, the company has continued this strategy of differentiating the consumer versus professional product lines. Apple's focus on design has allowed each of its subsequent products to create a distinctive identity. Apple avoided using the beige colors that were then common in the PC industry. The company would later drift from the multicolored designs of the late 1990s and early 2000s. The latter part of the decade saw Apple usinganodized aluminum; glass; and white, black, and clearpolycarbonate plastics among its build materials. Today many PCs are more design-conscious than before the iMac's introduction, with multi-shaded design schemes being common, and some desktops and laptops available in colorful, decorative patterns.[8]
Apple's use of translucent, candy-colored plastics inspired similarindustrial designs in other consumer products.[9] Apple's later introduction of the iPod, iBook G3 (Dual USB), and iMac G4 (all featuring snowy-white plastic), inspired similar designs in other companies' consumer electronics products. The color rollout also featured two distinctive ads: one called 'Life Savers' featured theRolling Stones song, "She's a Rainbow" and an advertisement for the white version had the introduction ofCream's "White Room" as its backing track[citation needed].
The iMac won several design competitions and awards, including Gold at the 1999D&AD Design Awards in the UK,[10] and "Object of the Year" byThe Face.[11] Various iMac models are held in the collections of museums including theHenry Ford, theVictoria and Albert Museum, thePowerhouse Museum, and theMuseum of Modern Art.[12]
iMac has received considerable critical acclaim, including praise from technology columnistWalt Mossberg as the "Gold Standard of desktop computing";[13]Forbes magazine described the original candy-colored line of iMac computers as being an "industry-altering success".[14] The first 24"Core 2 Duo iMac receivedCNET's "Must-have desktop" in its 2006Top 10 Holiday Gift Picks.[15]
Apple faced a class-action lawsuit filed in 2008 for allegedly deceiving the public by promising millions of colors from the LCD screens of all Mac models while its 20-inch model only held 262,144 colors.[16] This issue arose due to the use of 6-bit per pixelTwisted nematic LCD screens. The case was dismissed on January 21, 2009.[17]
While not a criticism of iMacper se, the integrated design has some inherent tradeoffs that have garnered criticism. InThe Mythical Midrange Mac Minitower, Dan Frakes ofMacworld suggests that with the iMac occupying the midrange of Apple's product line, Apple has little to offer consumers who want some ability to expand or upgrade their computers, but do not need (or cannot afford) theMac Pro.[18] For example, iMac's integration of monitor and computer, while convenient, commits the owner to replace both at the same time. For a time before theMac mini's introduction, there were rumors of a "headless iMac"[19] but the G4 Mac mini as introduced had lower performance compared to the iMac, which at the time featured a G5 processor.[20] Some third party suppliers such asOther World Computing provide upgrade kits that include specialized tools for working on iMacs.
Similarly, though the graphics chipset in some Intel models is on a removableMXM, neither Apple nor third parties have offered retail iMacGPU upgrades, with the exception of those for the original iMac G3's "mezzanine" PCI slot. Models after iMac G5 (excluding the August 7, 2007, iMac update[according to whom?]) made it difficult for the end-user to replace the hard disk or optical drive, and Apple's warranty explicitly forbids upgrading the socketed CPU. While conceding the possibility of amini-tower cannibalizing sales from the Mac Pro, Frakes argues there is enough frustration with iMac's limitations to make such a proposition worthwhile. This disparity has become more pronounced after the G4 era since the bottom-end Power Mac G5 (with one brief exception) and Mac Pro models have all been priced in the US$1999–$2499 range, while base model Power Macs G4s and earlier were US$1299–1799. The current generation iMac has Intel 5th generation i5 and i7 processors, ranging from quad-core 2.7 GHz i5 to a quad-core 3.4 GHz i7 processor,[21] however it is possible to upgrade the 2010 edition of the iMac quite easily.[22]
