This approach does make some sense though. You may really want a larger amount of RAM and didn't realize at first that the CPU you chose didn't allow for that. If they didn't show the larger RAM option you may think you are just out of luck on getting more RAM when in fact you can have it IF you change your CPU choice. There are other ways they could have handled this but none are "perfectly simple".This first attempt was done sloppily. After you've selected your CPU, it still offers you RAM options that are incompatible with the CPU you've selected, then asks you to go back and change your earlier choice if you don't want to change your selected RAM. Shouldn't this process be able to use enough Apple Intelligence to avoid offering an impossible choice?
