I like risky sports (relative for some people it might be boring) but when I have to work or even play I want stuff that just works. I can’t imagine using a laptop and wondering every day if this is the last update to my OS I might get. Sure Apple laptops might be great hardware, you might love the design, etc but just the fact that this question exists make it impossible to consider such hardware. TL;DR: I don’t know and I don’t want to care. Please support OEMs who are not making money by selling locked hardware.
