Eh, for some reason MacOS issues most often (in my experience) stem from plist preference files going corrupt in one way or the other. Nine times out of 10, if your Mac is doing something weird, or not doing something it should be doing, find the relevant plist and trash it, and suddenly it returns to full operational beauty.
As to what makes various random plist files go corrupt, I really don't know. It happens rarely enough to make it not very relevant, so I just do the plist dump, reboot, and say "here ya go!" The problems that this action fixes has never (as of yet) recurred on me, so there hasn't really been good reason to investigte further when there is lotsa lotsa work to be done elsewhere.
If I had massive loads of free time, or a recurring plist corruption issue, then I would certainly dig further. |
