The all-in-one Mac: a 24-inch 4.5K display, camera, speakers and keyboard with an M4 inside, 8-core CPU and GPU in the two-port base model and 10-core in the four-port models. 16GB (up to 32GB) at 120GB/s runs 7-8B language models but is no AI workstation, and the chip is two years old - Bloomberg reports an M6 iMac is close, so wait unless you need one now.

Wait iMac 724days since update

Past the usual gap between updates: one is due. Last updated October 28, 2024, iMac 24-inch (M4); the last 4 updates came every 512 days on average. Next: An iMac with the M6 chip, expected to be announced around 27-28 October and released Friday, 6 November 2026. (MacRumors, citing Bloomberg's Mark Gurman, 2026-10-18)
