Anyone know how to fix it? When I go to the MAS, and go to the Update tab, it shows me the updates available, but, I can't see what updates have already been applied. This started happening right after the keynote, when there was an issue with updates to Pages, Numbers, Keynotes not showing as available to update -- even though there was a number on the update tab. Ever since then, it's been b0rked. I've heard that deleting ~/Library/Caches can help things -- but, I'm just worried that I'll break something. Thoughts?
