News Apple M2 May Release in Fall 2022 as Part of 18-Month Mac Up Cycle

With the exception of Air and Mac Mini devices Macs are significantly more expensive for lowest configurations versus iPhones. So having a longer cycle isn’t rare. Plus they don’t sell in nearly the volumes that iPhone or even iPads do.

People must have forgotten the 18+ month refresh cycles for a lot of Intel Macs. The Mini I think got to almost 4 years at one point 2014 ->2018 models. People tend to hold onto computers a lot longer than phones. Be it Macs or even PCs.

Once they completely cut over to their own silicon across the board. They won’t really have any dependencies on hardware refreshes based on new Intel chips or graphics hardware. So those cycles could stretch out even longer.
