I was waiting for a MacBook Pro M6 Max and now I don’t know what to do, especially with the price increase I feel like I really screwed up not just getting an MBP M5 Max a month ago
Just buy now. DRAM prices are not coming down any time soon, and Apple may be forced to raise prices again.
The question is what will you be using if you don't.
Are you upgrading from a perfectly good machine? Then wait.
