I set permissions on my drive as no access for everyone. To make it worse I applied to all sub folders. Now mac will not boot. Also cd drive does not work so that is not an option for booting. Any suggestions please - need help
Hello Angel,
See this User Tip by Niel: I accidentally set a disk's permissions to No Access ...
If the disk in question is your Mac OS X startup disk and your computer stops starting up at the blue screen, restart with the Command and S keys held down, and enter the following commands:
mount -uw /
chown root /
chmod 1775 /
exit
The first response from BDAqua worked for me. I was a little iffy about typing commands, but it worked and wasn't as scary as I thought it'd be. Thanks for posting!
Start up holding Command+S
Let the code finish loading on it's own. It might hang for a second on certain lines before it completely stops loading so you can type.
mount -uw / (Press 'return')
chown root / (Press 'return')
chmod 1775 / (Press 'return')
exit (Press 'return')
System will reboot on it's own. If this was done correctly you should come to the login screen and your system will function like normal again. Another post mentioned to copy and paste these commands onto a doc so you can see where to add necessary spaces between characters. That was a good suggestion also.
Drive permissions to no access for everyone
