Im on macOS Sierra 10.12.5. I have customized a few things (finder window's toolbar, how to keep directories ordered by name etc) but sometimes (I think on restart, not sure) all this goes back to factory settings and I have to do it all over again. It is really annoying.
It seems people had this problem on older versions too but I prefer to ask again since it was like 4 years ago.
What can I do to prevent this? Thanks
