I was going to buy an M4 Mini to free up my M1 for work stuff only, and use the M4 for music making, but after a lousy trade-in offer, and atrocious support experience I’ve decided to keep and use my Intel MacBook Pro for music instead.
Despite its age and non-silicon processor, the old MBP handles Ableton and a bunch of plugins no sweat, and the M1 Mini is a reliable workhorse.
If I decide on an upgrade in the new year I’ll go for a second hand M2, I’m done with chasing the latest new shiny thing.
