MacBooks aren't that unrepairable, you just have to go to someone who isn't Apple. Apple will tell you that you have to replace the entire logic board, and then you go to the independent repair shop and they can fix whatever it was for $100.

I've repaired my MacBooks multiple times before (although not one in the last seven years, so maybe they are totally unrepairable, but I doubt it).

The main issue is that Apple will want to replace everything to avoid you coming back and saying it didn't work, when it's actually a different issue.

The soldered on RAM and SSD, while technically replaceable, make it a much more difficult process than just swapping some DIMMS and an m.2.

I understood the technical need for soldered on memory (physical limitations of SODIMM got in the way of power and speed requirements), but the soldered on SSD is just inexcusable considering flash memory is very much a wear item.
