Through a series of unfortunate events I managed to run:
sudo chown -R `whoami`:admin /usr
on my 10.10.5 machine. This has left it in an awkward state. I can no longer sudo
commands as sudo
is no longer owned by root on the machine.
I tried booting in to single user mode and chown
'ing /usr
back to root:wheel
but /usr
is a read-only file system in single user mode.
Apart from a total reinstall of OS X on the machine, is there anything else I can do to get the permissions on /usr
back to root:wheel
?
