With the introduction of the M4 series chips later this year, Apple will refresh its Mac lineup.

A detailed roadmap for the upcoming M4 Macs has been revealed by Bloomberg’s Mark Gurman in his latest Power On newsletter.  M4 Macs are expected to arrive around 2024, according to Gurman. MacBook Pro 14-inch and iMac 24-inch models will be targeted in the initial refresh.

Apple will introduce higher-end models throughout the rest of 2024 and early 2025 following the initial wave. It will include new MacBook Pros with the M4 Pro and M4 Max chips, including the 14-inch and 16-inch models.

Around the same time, the Mac mini will also receive an update with M4 and M4 Pro configurations. The MacBook Air lineup is expected to receive a refresh in spring 2025. During that time, Gurman mentions we can expect new 13-inch and 15-inch MacBook Air models with the M4 chip.

The professional desktop segment will also receive the M4 update later on in the cycle. In mid-2025, a high-end M4 chip will be added to the Mac Studio.

Last but not least, the mighty Mac Pro is slated to get an upgrade to the M4 Ultra chip by 2025, aimed at professionals with extreme processing needs. According to Gurman, Apple has internally tested a M3 Ultra chip, but its high-end desktops are likely to skip the M3 chip series altogether.

Gurman’s report reveals Apple prioritizes artificial intelligence (AI) with its M4 chip series. It is unclear what details will be covered in this focus.
