I recently upgraded to the lastest iWork '09, but the App Store keeps asking me to downgrade to iWork '13, and there's seemingly no way to "hide update" in Mavericks. Does anyone know how to take care of this? I've completely deleted the new Keynote, Pages, etc, but I can't figure out how to stop the App Store from bugging me with a reminder every day. I would rm the entire App Store itself, which I've never used, but I see that future OS updates will be delivered via this mechanism. I guess I could chmod 000 it until I want to check for OS X updates, but I was wondering if there was a better, more specific solution to stopping unwanted updates. Seriously it's as annoying as the Windows XP auto-updates were. At least there's no danger (yet??) that it will restart my computer at inopportune, random times, like XP did.
