Upgraded every old MacBook (2009pro, 2015 pro) I had with bigger harddrives and did small repairs with ifixit instructions. But you notice they get less repairable over time. The 2009 thing was built like a tank and you could upgrade ram, replace a broken GPU and this thing over all felt very repairable. I still works but isn’t that useful any more 16 years after release. 2015 was way less repairable.
