When I purchased my Early 2009 iMac, it came with 10.8 installed. I made use of the free upgrade to 10.9 via Apple’s website, and then increased it to 10.9.2, however since then I could not convince the Mac App Store to upgrade to 10.9.5. I would continually face a permission error - 513 - which would not give up the ghost no matter what I tried. (Repaired permissions, new user, root user, some shit in terminal that reset settings…)
Finally tonight I tried the only other option that someone suggested either on MacTalk or Apple Discussions - putting the iMac into Target Disk Mode and using another Mac to perform an upgrade using a Combo installer. So, I did that… watched with baited breath… restarted… and after about 5 minutes of grey screen/Apple logo/spinning circle, it finally came up with the login screen.
Check the About This Mac, and yay - it says I’m now running 10.9.5.
Except… When I log into Mac App Store to check for other updates, in particular iTunes, it first was suggesting the 10.9.3 update (!), then tells me that I have already installed iTunes 12 - however I am only running version 11.
I tried deleting the software update preference file, and a storeagent plist as well (as per some website’s suggestion), but it didn’t make any difference.
Is there some way to convince Mac App Store to recheck my system, and provide correct information and updates???
Even more annoying - I can’t simply go into Mac App Store and download iTunes manually… Doesn’t appear when you do a search…
