How can you ignore a software update in Mountain Lion?

I had a similar issue after having my hard disk replaced. Apparently the image used by the mac shop had newer versions of GarageBand and iMovie than I had. So the update always wanted me to enter a different AppleID. Frustrating. There have been other threads about this issue. One of the posts helped me.

Since I don't use these apps, I moved them from the Applications folder to a save folder. I then told Spotlight to ignore that folder. Apparently the updater uses the files maintained by Spotlight. Annoying problem solved.

I finally got sick of that bright-red icon alert, and removed "App Store" from my Dock.

LOL, probably saves me time and money, because I'm less likely to go shopping there now. (hint)

I am so over this. I've put up with it for 14 months now, I really want it to stop. I'll send $30 paypal to anyone who can tell me how to fix this. I've always updated to the latest OSX but they still have not fixed this bug.

And no, right-clicking does not bring up a contextual menu.

This workaround doesn't work in 10.8.5 any longer.

Which workaround, I missed it...

Can you just turn off automatic update notifications? I just did that and I think it solved the problem. We will see in a day or so if the message reappears.

The workaround of righ clicking it and selecting to hide it. Its also gone in Mavericks although you can turn off auto updates but ypull see them in the App Store when they're available. No way to really hide or ignore a soecific update.

I right clicked and selected 'hide' in order to hide the java update on my wife's machine, did not want her updating that for various reasons, but wanted the other updates in that bundle to still display. Now they're all hidden. So I'm trying to unhide them but the advice above doesn't work. In her App Store/Store menu there is no menu item to show all updates. She's on the latest version of Mountain Lion.

So, how do we unhide what we just hid?

This doesn't work anymore on macOS Sierra, is there a new trick now?

Try moving your cursor to the top left corner of the update to see if you get an option there.
