It came down to right-to-repair/upgrade. I’ve been a mac user my whole life. The 2012 MacBook pro was the last model that users could upgrade themselves. I got a decade plus out of those machines because I could upgrade them. They actually still run quite well, but Mac no longer includes those models in their software updates and no longer allows users to easily upgrade any of their laptops manufactured since. That was it for me. Got a System76 laptop and made the move. Couldn’t be happier.
