White MacBook running Leopard gets stuck at grey start up screen with spinning wheel after the Sharing & Permissions for everyone on the "Macintosh HD" was changed to "no access". I booted off of system disk and ran Verify Permissions and that gave me the message " Disk Utility stopped repairing permissions on "Macintosh HD" because the following error was encountered: The underlying task reported failure on exit" Archive and Install failed as well. Tried booting off of Disk Warrior CD but MacBook kept restarting while holding down the C-key. Luckily I did a back-up last week using Time Machine. But I would still like to refrain from a clean install if I can help it. There were a few new files and installs that occurred after the last back-up. Albeit not a major problem. So now I'm trying to change Permissions for the HD using Terminal. Current settings listed below. total 12 d-wx-wx-wt@ 2 root admin 1024 May 18 06:50 .Trashes --w--w--w- 1 root admin 4096 May 18 06:50 ._.Trashes drwxrwx---@ 47 root admin 1666 May 18 06:57 Macintosh HD lrwxr-xr-x 1 root admin May 18 06:32 Mac OS X Install DVD But when I use the "chmod 755 Macintosh\ HD/" command in the Volumes Directory I get "chmod: Macintosh HD/: No such file or directory. Are their 3 spaces in that command? Or am I missing something else? Thanks to all who reply.
