fixed : OSX 10.8.4 update doesn’t install repeatedly

Question :

Each time I try to update my Mac’s OSX 10.8.3 to OSX 10.8.4 using the Mac App Store, I can see the updater is already downloaded, but when I get a message to restart my Mac to complete the install, and I click on it… my Mac restarts and finally turns out to still be at OSX 10.8.3…

Is there a solution for this ?

Answer :


It’s simple, but not obvious : do a manual install of the OSX 10.8.4 Combo Update which you can download here :

That’s it.
