MacOS – Fixing mac user file permissions, not the system


Usually those files get wrong permission when coming from the network, even when I copy them from it, but mostly through "file sharing". So, definitely not talking about Disk Utility repair here, please.

But regardless of how the file got wrong permission, I know of two bad ways to fix them. One is CMD+I and the other is chown / chmod. The command line isn't all bad but isn't practical either.

Some times it's just 1 file I need to repair, sometimes it's a bunch of them. By "repair" I mean 644 for files, 755 for folders, and current user:group for all of them.

Isn't there any app / script / automator out there to do that?

  • Here's a script for you. I haven't tested this, so I'm going to set this Answer as a community wiki so others can fix my errors and infelicities.

    # Description: Fix file permissions like Cawas likes.
    # TFILES is an array of target files.
    # TUSER is the target user you want the files to be owned by
    TUSER=$(id -u)
    # TGROUP is the target group you want set on the files
    TGROUP=$(id -g)
    # chown everything to user:group:
    sudo chown -R ${TUSER}:${TGROUP} "${TFILES[@]}"
    # chmod to 644 for files, 755 for directories
    sudo chmod -R u=rwX,go=rX "${TFILES[@]}"
