When you do a clean system restore on a Mac (or really any computer, though the Mac system restore is fairly good already), the first screen that comes up after the clean restart should be the machine specs – “About This Mac” would work, but I’d prefer it all on one screen, including serial number, model name and year, memory and drive size, battery cycles – and access to the “System Information” app, as well as some sort of hardware test app. I’m sure they could make it pretty enough that it would run with brand-new Macs, too.
