The iMac
is a series of Macintosh
desktop computers offered by Apple Inc. The current Apple iMac features either an Intel Core i5, or Intel Core i7 processor, ATI

graphics or an ATI Radeon HD 6770M with options to upgrade to the ATI
Radeon
HD 6970M
(27" model only), and a choice of glossy 21.5" or 27" LCD screens.
While previous iMac models had a white polycarbonate enclosure as the iMac G5, the iMac had an enclosure shaped like Apple's Cinema Displays and styling reminiscent of the iPhone
, made using the same unibody assembly as the MacBook Pro
. Previous aluminum iMac models had a black plastic back, but later models have an aluminum back continuous with the front aluminum plate.
announced that the new iMac would be the second Macintosh
to use an Intel CPU, the Core Duo
. The introduction of the new iMac along with the Intel-based MacBook Pro
signaled the start of a six month transition from PowerPC
to Intel processors. The features, price, and case design remained unchanged from the iMac G5
. The processor speed, however, according to tests run by Apple using SPEC, was declared to be two to three times faster than the iMac G5.
Alongside the MacBook Pro
, the iMac Core Duo represents Apple's first computers to feature Intel processors instead of PowerPC
processors, a transition that completed in November 2006. Since the introduction of the iMac Core Duo, other lines have followed, including the introduction of the Intel Core powered Mac mini
on 28 February 2006, the MacBook
consumer line of laptop computers on May 16, 2006, the Mac Pro
on August 7, 2006, and the Xserve in November 2006, completing the Macintosh family transition to Intel processors.
In early February 2006, Apple confirmed reports of video display problems on the new Intel-based iMacs. When playing video on Apple's 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.
In late 2006, Apple introduced a new version of the iMac which included a Core 2 Duo chip and a lower price. Apple added a new 24" model with a resolution of 1920 x 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
. Except for the 17-inch 1.83 GHz processor model, this version also included an 802.11n draft card.
In March 2009, Apple released a minor refresh of the iMac line. Changes included a fourth USB port, one FireWire 800 port, removal of the FireWire 400 ports, and a slightly redesigned base. The exterior design was almost identical to the older Intel-based iMacs. The models were one 20-inch configuration and three 24-inch configurations (instead of two at each screen size as before). Apple doubled the default RAM and hard-disk size on all models, moving the RAM to the DDR3 specification. This revision also introduced a new smaller and more compact Apple Keyboard
that excluded the numeric keypad and forward delete key
in favor of the fn + Delete keys shortcut.
screen was introduced in 21.5" and 27" models, replacing the 20" and 24" 16:10 aspect ratio screens of the previous generation. Video card options entirely switched to ATI
, save for the standard onboard nVidia
card in the base model. The iMac's processor selection saw a significant increase. 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 16GB). On May 3, 2011, Intel's new Core i5 and Core i7 chips, based on the Sandy Bridge
microarchitecture
, became available standard, and for the first time in the iMac's history the complete lineup is now running on quad-core processors. The current iMac ships with the wireless Apple Magic Mouse
, or Apple Magic Trackpad and a wireless Apple Keyboard
, Bluetooth
and AirPort
cards, an internal FaceTime HD
camera, and a power cord.

Aluminum iMac
In August 2007, Apple introduced a complete redesign of the iMac, featuring an aluminum, glass and plastic enclosure. There is only one visible screw on the entire computer, located at the base of the iMac for accessing the memory slots. The back is no longer removable and is now a continuation of the aluminum body from the front and sides. The 17-inch model was completely removed from the lineup.In March 2009, Apple released a minor refresh of the iMac line. Changes included a fourth USB port, one FireWire 800 port, removal of the FireWire 400 ports, and a slightly redesigned base. The exterior design was almost identical to the older Intel-based iMacs.
