I absolutely cannot figure out what to do in order to fix an Apple computer when it’s bugging out. Is it a part? The OS? Something external? How am I supposed to diagnose this fucker with so little information? Windows is rapidly heading down the same road. Linux will remain the final bastion of those who fix their electronics themselves
Or do the same basic troubleshooting you would for any other computer. It sounds like the person you're replying to doesn't know how to do that. They should learn. It's not that hard.
macOS is Unix. Everything can be logged and reported through the terminal if you want more debugging information. There are also power tools you can download that give you better GUI-based control over a myriad of things.
Though it’s worse now than it was ten years ago. Apple’s software has been suffering under Tim Cook and it’s probably not going to get better until he’s gone.
Mac is Linux? You debug it the exact same way, except unlike Linux, you don’t have to worry about 50 different distros, so it’s a lot easier to find solutions. Debugging a hardware issue is just as hard as any other platform… what are you even trying?
The one thing I'd agree is that it tends to be harder to fix hardware issues. Well, on the new one's you just don't because it's soldered, but a friend's late 2015 27 inch imac has a borked SSD, and to replace it, we'd need to take off the glued on screen.
Softwarewise, I prefer the issue-finding experience to the windows one, though.
