Remove applications from Software Update I have two applications showing up in Software Update that I didn't install, don't exist anywhere on any volume attached to my computer (and never have), and I would like to remove them. When I click on the "Update" button an Apple ID I've never heard of shows up (a different ID for each application). I'd install the apps just so I can delete them, but both cost money that I'd rather not spend.

This question never really got a useful answer, and I couldn't find anything else relevant on Ask Different. I rebuilt the Launch Services database but no dice.

My only guess is that some applications I have, which were obtained through a friend ;), were originally installed using these Apple IDs or are otherwise associated with them, and that info is being read by Software Update. Is there some centralized place I could edit to remove these entries? I would rather not grep -r "random_letters@mail.ru" /Applications if I don't have to, as it's over 32GB, but if that's the only way I'll bite the bullet and do it. I was rather hoping there'd be a .plist somewhere I could edit real quick...
Somebody asked about it on Apple Discussion Groups here. The answer is:

For the software update you would like to hide - make sure the full description of the update is shown - click "More..." if needed to show the full description

Right click on the update window.  Select "Hide update"

This will hide the update and it will not show in the App Store Updates Window or counted on the dock icon.

To restore - select "Show all software updates.." which is now shown in the App store "Store" menu.  Then "Reload Page" from the Store menu.
