My friend has two logins on his iMac and one of them has some kind of corruption that prevents the finder from opening. I tried to access the desktop files he needs from that login from the working one but the all the folders under his login are marked with a red minus sign and I cannot open them. I checked permissions and did a get info that said that I don't have permissions access. What can I do to retrieve his files? Thanks in advance.
I recently had a similar problem with my iBook on OS 10.4
Many things I tried would work for a short time, but the ultimate solution ended up being to boot the iBook into FireWire Disk Mode (Holding gown 'T' at the startup chime, if I remember correctly), attaching it to another mac with a firewire cable, disabling permissions on the mounted HD (Get Info > Ignore Permissions on this Volume) and copying my files out before formatting and reinstalling.
Hopefully you won't have to resort to such a drastic move, but it ended up being the only thing that fixed mine.
