how do i delete app updates

One of the key things to check is where these apps may be. If you have a copy lurking in your system (backed up, perhaps) it will continue to show as requiring an update.

Check them out via Spotlight or the free Easy Find App. Then delete all you find once you are sure.

Fortunately, the purchase records will always stay on your account so if you change your mind and want to reinstall, you can.

I, too, came here looking for a solution, but accidentally found the solution on my own.

I have an old HP4MV that still works reliably, so I naturally don't want to delete my HP printer driver software, just to prevent those annoying update reminders.

Here's what I've found:

When the update pops up, go to the Mac App Store (MAS), and Right-Click on the update **Name** - then choose "Hide Update".

If the update is grouped with another update (or other updates), you must first click on the small "More…" button/link to expand the list. Then Right-Click on the **Name** of the specific update you want to hide.
