iMac is a range of all-in-one Macintosh desktop computers designed and built by Apple Inc. It has been the primary part of Apple's consumer desktop offerings since its debut in August 1998, and has evolved through seven distinct forms.

In its original form, iMac G3 had a gumdrop or egg-shaped look, with a CRT monitor, mainly enclosed by a colored, translucent plastic case, which was refreshed early on with a sleeker design. The second major revision, iMac G4, moved the design to a hemispherical base containing all the main components and an LCD monitor on a freely moving arm attached to it.

In October 2014, the seventh major revision of the iMac was announced, whose main feature is a "Retina 5K" display at a resolution of 5120 × 2880 pixels. The new model also includes a new processor, graphics chip, and IO, along with several new storage options. The seventh major revision of the iMac was announced in October 2015. Its main feature is a "Retina 4K" display at a resolution of 4096 × 2304 pixels. It has the same new processor, graphics chip, and IO as the 27-inch iMac, along with several new storage options.

On 5 June 2017, Apple announced a workstation-class version of the iMac, called the "iMac Pro". The iMac Pro shares the design and screen of the 5K iMac, but is colored in Space Gray rather than silver. It comes with Intel Xeon processors and standard SSD storage. The iMac Pro will ship sometime in December 2017.


The announcement of iMac in 1998 was a source of controversy and anticipation among commentators, Mac fans, and detractors. Opinions were divided over Apple's drastic changes to the Macintosh hardware. At the time, Apple had suffered a series of setbacks as consumers increasingly opted for Wintel (Windows PCs) machines instead of Apple's Performa models.

The designer behind iMac's case was Jonathan Ive. Ken Segall was an employee at an L.A. ad agency handling Apple's account who came up with the name "iMac" and pitched it to Steve Jobs. Jobs wanted the product to be called "MacMan", but eventually warmed to Segall's suggestion. Segall says that the "i" stands for "Internet", but also represents the product as a personal and revolutionary device ('i' for "individuality" and "innovation").

Apple later adopted the 'i' prefix across its consumer hardware and software lines, such as iPod, iBook (later MacBook), iPhone, iPad and various pieces of software such as the iLife suite and iWork and the company's media player/store, iTunes.

Attention was given to the out-of-box experience: the user needed to go through only two steps to set up and connect to the Internet. "There's no step 3!" was the catch-phrase in a popular iMac commercial narrated by actor Jeff Goldblum.
