If you’re thinking of installing the 10.8.5 supplemental update, I would wait till 10.8.6 or even just wait till 10.9 Mavericks is released.
Well… if you’re like me and you have installed the 10.8.5 supplemental update. Good luck getting anything to work. I had installed some applications primarily used for backup. Now when I go to use these application I get the following message saying these applications were created TextEdit and did I want to continue?
I’m like WTF are you on about? Then I started a little Google search and discovered I wasn’t the only poor sod, who was having issues. Seriously APPLE you need to pick up your game, you just dropped it the iPhone 5C & now a dodgy system update.
