In Snow Leopard if you try to install a program while another is installing you get an error message saying “Waiting for other installations to complete.” But what do you do if the message stays there after the program has finished installing?

Today I was stuck with this message even though there was no installation in progress. The computer won’t’ restart as it wants’ to wait for the update to finish first!

The first option around this is to ‘force quit’ the installer. Press Apple-option-esc then select ‘Software Update’ and ‘Force Quit’.

If that doesn’t work try deleting the following 2 files from your Library/LaunchDaemons.

    I tried “sudo killall installd” and the first time it asked for my password but stopped responding, and after that it never prompted me for my password.

    i did force quite it and update then again open the installer, and now they stuck on waiting for other installation to complete.
    any ideas?

    THANKS SOOOO MUCH!!! “sudo killall installd” worked great. After almost paying the exorbitant fee apple charges for their terrible customer support and lugging a 24″ iMac into the genius bar where they were too incredibly stupid to fix it, not to mention they thought the only solution would be to wipe the entire computer and then MAYBE it would work after we reinstalled everything, I was glad to find this.

    sudo killall installd worked for me too!

    Restart of my iMac solved the problem. Did not try ‘sudo killall installd’ first though.
