have mistaken performed a
sudo chown myuser /
on my macbook...
now it claims it cannot load several kexts like:
i need to repair the default permissions....but disk utility already said i cannot repair the disk due to this error:
the underlying task reported failure on exit
already tried to repair using the install dvd too.
found on the web this procedure:
Boot off the OS X CD (reboot, hold C while booting).
The installer will load up, go to Utilities in the menu and run Terminal.
Type df and look for the drive that has your Mac system mounted---you'll have to unmount this. On my MacBook Pro, it was /dev/disk0s2.
Type umount /dev/disk0s2, replacing disk0s2 with whatever disk your OS lives on.
Type fsck_hfs -r /dev/disk0s2. If you umounted the wrong thing, it will complain that you can't repair a mounted drive. Go back and umount the right thing and repeat this step.
(they forgot to add the step to re-mount...but its ok..)
and this one:
Single user mode (boot with -s) and then type
fsck_hfs -r /dev/volumename
will any of those save me from a archive and install?
HELP!! Those warnings cannot be good... but the system is booting and working fine till now.
