Sittin’ on the dock of the… Hey!

Sometimes when my MacBook Pro is at home, my family go onto the guest account. However, someone was on it recently but weren’t able to use it because the dock was filled with question marks. How do I fix this? Chris Emerson Those question marks appear when the Dock shortcut can’t find the app it points towards. This can be because the original has been deleted or moved, but in your case I think it’s more likely to be a permissions fault. If you log back into your own user account (which presumably has administrator access) and bring up the Get Info panel for the Applications folder, you’ll probably find that it doesn’t show any sharing permissions for the ‘Everyone’ group. This needs to be ‘Read only’ at least, in order to be able to see the apps. You can correct this yourself manually or run Repair Permissions in Disk Utility.
