I don’t believe that there would be a cost associated with retool for a different RAM baseline either. Each new model year requires a board spin to accommodate a new processor and other updated chips anyways. And retooling the assembly of electronics is more about software and instruction updates than actual mechanical changes anyways.
The issue with 8GB is not on the manufacturing side. It is all about sales and greed. And the huge profit Apple can rack in by overcharging for upgraded RAM. As long as 8GB will work
well enough, Apple will keep it as a baseline. Apple is already making noises like
“Apple AI only requires 8GB to run”, not that it runs well just that it’s
sufficient. The only things will make Apple upgrade the baseline are:
- Basic software won’t run.
- People stop buying new 8GB hardware.
So I would predict the lowest cost iMac, Mini, MacBook Air and MacBook Pro that come with the lowest end M4 chips (possibly binned M4) will still be offered with 8GB. This is so Apple can make huge margins on selling other configurations with more RAM.
