Macos – Can’t install updates after upgrading to Mac OS X Snow Leopard

macmacososx-snow-leopardtroubleshootingupgrade

I have just upgraded to Snow Leopard over a Leopard install.

After the reboot I get a notification that new updates are available. I click "Install and restart", I get a license text, I click "Agree" but nothing happens. Nothing gets installed.

If I open the Console, the messages I see right after I click "Agree" are below, but I think the problem is related to the first message.

Any ideas?

Thanks.

Just found the solution on this forum thread.

  1. In Finder, go to your home folder (the one with the house icon next to it in the sidebar)
  2. Select navigate to Library > Preferences > byHost
  3. Delete all files inside
  4. Restart your computer.

Or, from Terminal, run

rm ~/Library/Preferences/byHost/*
