Apple does not make any Macs with ECC RAM any more. This was the reason I always used Mac Pro machines, and at the end, iMac Pro: those machines had ECC RAM, and incidentally always seemed more stable over months and years than the MacBook Pros I had, which didn’t. (Of course, there are a lot of reasons why a laptop might crash or malfunction an order of magnitude more than a desktop machine. The benefits of ECC RAM are really hard to catch definitively in the wild. We know they exist though, so I’m in the “it’s insane not to use ECC RAM for any use case that persisting data and then reading it back later” camp.)
