Apple unveils new thin and colourful iMac with M1 chip


But the integration of the Apple M1 chip also means a new design… and no more bulging backs. It’s thin, at just 11.5mm thick for an all-in-one that displays on a Retina 4.5K (4480 x 2520 pixels) screen with 500cd/m² brightness and True Tone technology (automatic color temperature adjustment). The cooling system requires only two small fans with a noise level of 10 dB.
