Apple iMac ALL-IN-ONE NEWEST MODEL 2021 M1 Chip 256GB SSD 8GB 24" 4.5K (4480×2520) RETINA MacOS Big Sur SILVER Keyboard Mouse

Only 11.5mm. Now that’s thin.
This extraordinary design is only possible thanks to M1, the first system on a chip for Mac. It makes iMac so thin and compact that it fits in more places than ever. M1 integrates the processor, graphics, memory and more onto a single chip. That let us put an entire computer into a space so small it practically disappears.

See the big picture. And all the details.
See it all in sharp, glorious detail on the immersive 24‑inch 4.5K Retina display. The P3 wide colour gamut brings what you’re watching to life in over a billion colours. Images shine with a brilliant 500 nits of brightness. Industry-leading anti-reflective coating delivers greater comfort and readability. And True Tone technology automatically adjusts the colour temperature of your display to the ambient light of your environment, for a more natural viewing experience. So whether you’re editing photos, working on presentations or watching your favourite shows and movies, everything looks incredible on iMac.
