They did that. But when the AI craze hit turned that all the 8GB base model Macs didn’t have enough space for even basic models (in addition to the 1-2 electron apps you can run simultaneously).
Of course seems like local AI is more or less a flop in the consumer market at least?
But still IMHO even for general use macos with 8GB is almost unusable unless you use it like an Ipad.
