Apple parts are unnecessarily expensive though. And they've already started rolling out new firmware in place to reject parts from third party sources. This will essentially force you to buy parts from them at high prices - I remember when I bought a Mac Mini, Apple RAM and SSD was nearly double the price of its competitors for similar or better specs. (I naturally chose to buy the non-Apple parts. Ofcourse, they've already made sure that your loyalty to them doesn't go astray by soldering the RAM and SSDs now!). And they will continue to make even more hard to repair devices. Nothing will change on their part here - Apple will not give you the ability to customise your hardware or software from non-Apple sources, as that will give you the freedom to leave their ecosystem.
