Generally reliable technology leaker Dylandkt has claimed in a Twitter post that Apple's much-anticipated M2 processor - the sequel to the popular M1 in much of the current Mac range - will make its debut in a new model of MacBook Air that will be released in the first half of 2022.

It had previously been rumoured that the new chip would appear in this autumn's new MacBook Pro models, but sources now suggest that Apple will settle for a souped-up version of the M1 chip in that device - provisionally known as the M1X - rather than the full-version M2 update.

The M1X will be faster than the M1 (which is already quick enough to impress in our review of the late-2020 MacBook Air, among other devices) but it won't incorporate the more fundamental upgrades expected from the M2. The biggest change is that the M2 will be based on 4-nanometre (nm) technology, whereas the M1 and M1X are based on 5nm.

Given that the earliest of these aren't expected to launch until autumn, however, you may be looking to buy before then.
