Trying to open & work with a file in one of my folders I get a message sayign that I don't have "permission to write to the folder that the file ... is in." I have no idea how this "lock" could ahve been set or how to undo it so I can work with my files. A week ago I migrated from my old McBook Pro to a new iMac, but have not had any other such permissions problems.

iMac, Mac OS X (10.7.4), Just migrated from MacBook Pro

    Select it in the Finder, choose Get Info from the File menu, and change the settings under Sharing & Permissions.

    Select the folder in question. Press COMMAND-I to open the Get Info window. In the bottom panel, Sharing & Permissions, take a snapshot of what is displayed - COMMAND-SHIFT-4 and select area with crosshairs. Pic is saved on your Desktop. Use the camera icon in the toolbar above here to upload the image to your reply message.

    Thanks, this worked. Just noticed that a whole number of my folders have been locked in this way (i.e. without my doing anything, switched from 'read & write" to "read" only). Anyway of changing them all back in one fell swoop?

    Open the Terminal inn the /Applications/Utilities/ folder, type or paste in:


    chmod u+rwX


    followed by a space, drag all the folders into the Terminal window, and press Enter. To apply this to subfolders, use:


    chmod -R u+rwX
