In addition to the new MacBook Pro, Mac mini, and iMac, Apple is also working on two new computers with M4 chips. Bloomberg journalist and insider Mark Gurman told about it in the latest Power On newsletter.
We're talking about the updated Mac Studio and Mac Pro. Mac Studio will be released sometime in mid-2025. Perhaps the release will take place in June at WWDC. While the Mac Pro will debut in the second half of 2025.
Both Mac Pro and Mac Studio will use the M4 Ultra chip, which hasn't been released yet.
By the way, Apple has so far released only the standard M4 processor. It appeared in the iPad Pro in May 2024.
