I've tried updating my software to 10.9.2 and 10.9.3, but it won't go. After trying to install it and restarting my laptop, I am still stuck on version 10.9.1. My app store says I should check my purchases again because updates failed. Apps such as iTunes, Pages and others also do not work anymore.

How can I fix this?

  • Which model of MacBook Pro do you have?

The possible solution in your case can be doing a combo update, but this may erase all the data from your drive.

  • I have done a combo update, but it still doesn't work. When I restart my laptop again, it says "updates aren't installed"

  • I check for software updates and then click install whenever there is one in the app store. It starts installing and then when it restarts, it says updates were not installed

    That is a Delta update, Download the Combo Update from here support.apple.com/kb/dl1746 and see if this works.

  1. Sign out of the App Store under Store > Sign out (in it's menu bar)
  2. Sign back into it with your Apple ID and Password
  3. Attempt the update again following re-authenitication
