Q: HD Privilege change now Mac Mail won't open
Couple of issues, self-inflicted:
I changed the HD Read-only Privilege for Everyone to No Access and then hit "apply to enclosed items". I bailed after a few minutes, changing my mind with a restart. On re-boot, I am now getting the pop-up "Library needs to be rebuilt to open applications". I keep having to enter my PW for this.
Also, Mac Mail now will not open. This is a big problem and I don't know where to start.
I did repair permissions. Is there an easy way to revert back to previous default permissions and privilege defaults to get things working like they were before?
MacBook Pro, OS X Yosemite (10.10.4)

I hope you have a recent backup because I think the answer is “erase and restore from backup”. Obviously not every file and directory is supposed to be “no access” - in most cases everyone should be read only. But I’m not sure that every file should be read only for everyone. You can try - I don’t think you can do more damage than has already been done. If you don’t have a backup you’ll want to save your data before you experiment any further.
