Apple hefur gefið út uppfærslu á Mountain Lion, sem er nú komin í útgáfu 10.8.4. Þetta verður að öllum líkindum síðasta uppfærslan fyrir stýrikerfið í ljósi þess að Apple heldur hina árlegu WWDC ráðstefnu í næstu viku þar sem Mac OS X 10.9 verður væntanlega kynnt.
Með uppfærslunni lagaði Apple ýmsar litlar villuar varðandi Microsoft Exchange, Wi-Fi tengingar og iMessage. Hægt er að sækja uppfærsluna með því að fara í App Store í tölvunni þinni eða sækja uppfærsluna héðan.
