Q: Changed Macintosh HD permissions. Can't boot into Mac OS X.
Hey.
I changed the permissions of the Macintosh HD disk for everyone from Read Only to None to prevent other users on the network from reading the entire disk. Since then, applications wouldn't launch, and now after rebooting, the progress bar stops at just under half way. I'm running the latest version of OS X Yosemite.
I've spent some time trying to fix this issue using different methods online.
I have attempted:
- Booting into Disk Utility, repairing the permissions and the disk.
- Resetting Home Directory Permissions and ACLs using Terminal and the resetpassword command as explained in this article.
- Restarting with the Command and S keys held down, and entering the following commands from this discussions post:
mount -uw /
chown root /
chmod 1775 /
exit
Currently, the progress bar is stuck, however this time, a cursor is displayed, and I'm able to access the Mac remotely using TeamViewer. I guess this shows that something is running in the background.
My latest Time Machine backup isn't so recent and may not be complete due to lack of space on the backup drive, therefore I'd hate to have to restore the system using Time Machine.
I'm looking for a fix to revert my idiotic mistake. Does anybody have a solution?
Mac mini, OS X Yosemite (10.10.4), mid 2011
