MacBook Air mid 2013 cannot update to OS X 10.10.4

I had the same problem - update couldn't be found for 10.10.4 and the update check kept spinning. I'm not sure the machine type matters as I'm using a late 2014 Mac Mini.

I did an update earlier on an early 2015 13" Retina MacBook Pro without any problems. However, it was previous to the bundling of the OS with iTunes. I updated the OS, and then later in the day iTunes 12.2 was available and I updated it.

The only suggested file I found to delete '/Library/Preferences/com.apple.SoftwareUpdate.plist' which I deleted and then restarted the machine. It found the 10.10.4 update (containing iTunes 12.2) in the Mac App Store which I was able to apply. The plist file I removed did contain the following which shows a reference to iTunes 12.2 which was not in the list of available apps to update:

Fixed!

The solution that worked for me was:

- Remove the Library/update content

- Remove /Library/Caches/com.apple.SoftwareUpdate/

- Remove /Library/Preferences/com.apple.SoftwareUpdate.plist

- Restart

- Update normally everything from the App Store

Hope it helps. Thank you everyone trying to help.

Thanks Rutolf, these steps fixed it for me!

Thank you Sir.

Hi Rutolf

My MacBook Pro is doing the ecsact same thing as Eva's Air, and I really want to fix it with your solution, but I just can't find the steps no matter how hard I try (I'm from Denmark, and my setup is danish as well). So if you could tell me, how to remove my Library/update content etc. I would be very grateful!

If you try the following it may get you going without any additional steps. From Terminal:

sudo softwareupdate --reset-state

You should probably quit App Store then try again.
