Since updating to 10.7.3 from 10.7.2, Preview has been complaining that documents can't be saved because the file is locked. If I choose "Save Anyway" then Preview complains that I don't have permission to save the file. My user has Read & Write permission when I Get Info for the file.


I can workaround the problem by using File > Duplicate; however, it's sort of a pain. Also, Preview will always complain that the file is locked at least once when auto-save fails.


Thanks in advance for any help!

    Boot from your recovery partition by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.


    When the recovery desktop appears, select Utilities ▹ Terminal from the menu bar.


    In the Terminal window, enter “resetpassword” (without the quotes) and press return. A Reset Password window opens.


    Select your boot volume if not already selected.


    Select your username from the menu labeled Select the user account if not already selected.


    Under Reset Home Directory Permissions and ACLs, click the Reset button.


    Select ▹ Restart from the menu bar.

    Thanks Linc, that did the trick!


    P.S. I guess I should use a firmware password now that Lion makes it super easy to reset one's password!

    Unfortunately, this problem is still happening for new files created since using Linc's solution.


    Any ideas for a permanent fix?

    Launch the Terminal application by entering the first few letters of its name into a Spotlight search. Drag or copy -- do not type -- the following line into the window, then press return:


    chmod -R -N ~



    If you get an error message about permissions, enter this:


    sudo !!

    You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.


    Then repeat the steps in my last message.

    Hi Linc,


    Your answer was useful again after I had a kernel panic, and then PowerPoint refused to save files, and Word kept crashing trying to open files due to permissions issues. One tip for people who don't run as admin is that the user running the commands has to be a sudoer. Also, there's one chmod that always fails to clear for me, but it doesn't seem to prevent everything else from working again:


    chmod: Failed to clear ACL on file ubiquity.socket: Invalid argument

    Thanks Linc. After having repetead weird problems (like Preview displaying old stuff all the time), tried the Cmd-R reset password solution that didn't work.

    But the

    chmod -R -N ~

    (as root) did work.


    Would the problem be linked to a Leopard to Lion upgrade? ACLs being different in Lion?
