When reading something like this I can’t help but wonder what the big PC makers do, but figuring that out seems like it would be pretty daunting given the large number of models even a single vendor makes.
Having so few models, plus firmware updates in the OS, probably made figuring this out so much easier than it would be in PC land.
Also: poor 2019 iMac. It’s a nice model but came out right before the Apple Silicon transition. It’s lifetime was never going to be what it could have been.
