After over a year and a half, Apple is updating the Mac Studio with a curious new quirk: it straddles two generations, with an M4 Max for the base model and an M3 Ultra for the upgraded model. You can preorder both versions at Apple’s site for $1,999 (M4 Max) and $3,999 (M3 Ultra), and they’ll be available to buy on March 12.

Apple explains why the M4 Ultra isn’t available with the new Mac Studio. Still, it doesn’t mean it won’t be released.

However, Apple’s comments indicate the Cupertino firm may skip the M4 Ultra, as it may opt to update its most powerful chips on a lengthier schedule than previous M-series processors.
