Are you talking desktops or laptops? I’ve had no issues with my Air from 2011 and 2017. Multiple iMacs have had no issues other than a failed hard drive in the first Intel iMac, but I changed that out myself. But I suppose the days that this level of user serviceability are over, so you probably have a good point!It’s definitely worth it on macs. They break a lot out of warranty. Usually there ends up being a repair program, but I always seem to have to get my repairs before Apple realizes they have a design flaw.
