Apple refreshes Mac family with 21.5-inch 4K iMac and new 5K models

Apple overnight refreshed its family of iMac all-in-one devices, introducing a new 21.5-inch iMac with a 4K display, and kitting out the remainder of the line-up with new internals.

A 21.5-inch iMac now starts at AUD$1,699, and features 1.6GHz fifth generation Intel Core i5 processor, 1080p display, 8GB of RAM, an integrated Intel HD Graphics 6000 GPU and a 1TB HDD.

The 4K 21.5-inch Ultra High Definition iMac starts at AUD$2,299, features a 3.1GHz Intel Core i5 processor, an Intel Iris Pro Graphics 6200 GPU, 8GB of RAM, and a 1TB HDD.

Users are able to upgrade the RAM and HDD of both models.

Apple's entire range of 27-inch iMacs now feature 5K displays, boasting a resolution of 5120×2880 pixels. An entry level model starts at AUD$2,799. This boasts a 3.2GHz sixth generation Intel Core i5 processor, 8GB of RAM, a 1TB HDD, and a AMD Radeon R9 M380 GPU with 2GB of VRAM.

At the high-end, users can request a built-to-order 27-inch iMac that retails for AUD$6,479. This model includes a 4GHz quad-core sixth generation Intel Core i7 processor, 32GB of RAM, a 1TB solid state drive, and a AMD Radeon R9 M395X GPU with 4GB of VRAM.

All models are available to order now.

Tying in with the launch of the refreshed iMacs, Apple unveiled a new keyboard, mouse and trackpad. Respectively named the Magic Keyboard, Magic Mouse 2, and Magic Trackpad 2, all three eschew AA batteries for integrated batteries that can be recharged using a Lightning cable. Apple says the new accessories should last at least a month before needing to be topped up.

Notably, the Magic Trackpad 2 utilises the same depth-sensing Force Touch technology found in the Apple Watch and Apple's latest MacBooks.
