Apple's full M4 Mac lineup just leaked including its 2024 and 2025 plans

Apple might have only started to sell some M3 Macs not all that long ago - October 2023, in fact - but we have already started to see more than a few leaks that suggest the new M4 chips are just around the corner. What's more, it now looks increasingly likely that Apple is getting ready to begin launching those M4 Macs sooner rather than later, with the entire lineup of laptop and desktop machines set to be refreshed.

If that is indeed the case, it would mark the first time that the entire Mac lineup has used the same generation of chips since the move to Apple silicon began. Previously, some Macs skipped entire generations - the iMac skipped the M3 and the Mac Pro skipped the M1, for example. But that's all going to change with the release of the M4 series of chips.

That's according to Bloomberg's Mark Gurman, writing in the weekly Power On newsletter this past weekend, at least. According to Gurman, Apple is getting ready to begin an entire lineup overhaul later this year and then continue that through 2025. In fact, Gurman has gone so far as to share the entire roadmap for all of this. However, it's important to remember that the plans could change before the rollout is complete depending on a variety of things, not least chip availability.

Assuming Gurman is on the money and Apple doesn't make changes, however, we can expect things to begin to change around the end of this year. Gurman says that a low-end M4 MacBook Pro and a new 24-inch M4 iMac will launch before the end of the year. Then, a new 14-inch MacBook Pro will be joined by a new 16-inch version, both powered by M4 Pro and M4 Max chips. In terms of timing, expect that to happen at the end of 2024 or early in 2025, Gurman says.

Gurman believes that the Mac mini will also be updated to sport M4 and M4 Pro chips on the same late 2024, or early 2025 timescale before the MacBook Airs receive their own M4 refresh in spring of next year. The Mac Studio is then expected to receive new high-end M4 chips in the middle of 2025 with things being rounded out by a new Mac Pro, powered by the M4 Ultra, arriving in the second half of 2025.

That could make for quite a lineup but it remains to be seen whether everything will stick to that timeline or if we should expect things to change between now and the end of that timeline.
