The evolution of the imac 

In this post, we will review The Evolution Of The Imac, imac models by year and evolution of mac os. iMac is a family 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. Inspired by the iPod, Apple unveiled its polycarbonate white iMac G5 at the Apple Expo in Paris. Just two inches thick, Apple dubbed it the world’s thinnest desktop computer. It included a built-in SuperDrive, a PowerPC G5 processor, an NVIDIA GeForce FX 5200 Ultra graphics processor, iLife 2004 and OS X Panther.

The evolution of the imac 

iMac is a family 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, the 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 notable for its slot-loaded optical drive. The second major revision, the 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. The third and fourth major revisions, the iMac G5 and the Intel iMacrespectively, placed all the components immediately behind the display, creating a slim unified design that tilts only up and down on a simple metal base. The fifth major revision (mid-2007) shared the same form as the previous model, but was thinner and used anodized aluminum and a glass panel over the entire front. The sixth major revision (late 2012) uses a different display unit, omits the SuperDrive, and uses different production techniques from the older unibody versions. This allows it to be thinner at the edge than older models, with an edge thickness of 5.9 mm (but the same maximum depth). It also includes a dual microphone setup, and includes solid-state drive (SSD) or hard disk storage, or an Apple Fusion Drive, a hybrid of solid state and hard disk drives. This version of the iMac was announced in October 2012, with the 21.5-inch (55 cm) version released in November and the 27-inch (69 cm) version in December; these were refreshed in September 2013, with new Haswell processors, faster graphics, faster and larger SSD options and 802.11ac Wi-Fi cards.

In October 2014, the seventh major revision of the 27-inch (69 cm) iMac was announced, whose main feature is a “Retina5K” 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.[3] The seventh major revision of the 21.5-inch (55 cm) 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 I/O as the 27-inch iMac, along with several new storage options.[4]

On June 5, 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. Apple began shipping the iMac Pro in December 2017.

On July 27, 2010, Apple updated its line of iMacs to feature the new Intel Core “i-series” processors across the line. The 21.5″ models now feature the Core i3 processor, but these are upgradable to the Core i5. The high end 27″ features a Quad-Core i5 processor, which is upgradable to a Quad-Core i7. On this date Apple also announced its new “Apple Magic Trackpad” peripheral, a trackpad similar to that of MacBook Pro for use with iMac or any other Apple computer. Apple also introduced a AA NiMH battery charger intended to simplify the use of batteries in these peripherals. Apple offers an option to use a solid state drive instead of a large mechanical drive.

On May 3, 2011, Apple updated its iMac line with the introduction of Intel Thunderbolt technology and Intel Core i5 and i7 Sandy Bridge processors as well as a 1 mega pixel high definition FaceTime camera, features which were first introduced in the MacBook Pro line in February 2011.

On October 23, 2012, a new iMac was announced (for a November/December release) with a substantially thinner edge, new Apple Fusion Drive, faster processors (Intel Core i5 and i7 Ivy Bridge) and graphics along with updates to the ports, but with the same overall depth (stand depth: 8 inches (20.3 cm)). To reduce the edge, the SuperDrive was removed on these iMacs.

On October 16, 2014, a new version of the 27-inch (69 cm) 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 I/O, along with several new storage options. This computer was designed with professional photographers and video editors in mind, with the 5K resolution allowing 4K video to be played at its native resolution in Final Cut Pro, with room for toolbars on the side.

On June 6, 2017, Apple’s 21.5-inch iMac, which has a “Retina 4K” display at a resolution of 4096 × 2304 pixels, and the latest Intel 7th generation i5 processor, was announced. The iMac has Turbo Boost up to 3.6GHz supported, and 1 TB hard drive. Apple’s iMac with 4K display has Intel Core i5 quad-core processor with 3GHz or 3.4GHz clock speed. The RAM on board is 8GB, and it will support Turbo boost of up to 3.8GHz. This iMac has options of 1TB hard drive or 1TB Fusion Drive. This 21.5-inch iMac also has the option of Radeon Pro 555 with 2GB of video RAM for graphics or a Radeon Pro 560 with 4GB of video RAM. Apple’s 27-inch iMac with the 5K display comes with the quad-core Intel Core i5 processor, which is clocked at 3.4GHz, 3.5GHz or 3.8GHz. This iMac supports Turbo boost of up to 4.2Ghz, and comes with 8GB RAM option.[

In March of 2019, Apple updated the iMac to feature 9th-generation Intel Core i9 processors and Radeon Vega graphics. Unlike most other Apple releases, Apple opted not to announce the iMac at an event, rather to update the specs and release a press statement. For the first time, the iMac can support 6-core or 8-core Intel processors. Apple claims the 21.5-inch model is up to 60% faster than the previous model, and the 27-inch is up to 2.4 times faster. The exterior of the machine remained the same as the previous model.
