Hello, forum I recently killed my father's mid-2012 15" rMBP running Mountain Lion (10.8.2) by unwittingly installing the Thunderbolt Update 1.2. <this issue> I have since backed up the data using an HFS+ formatted HDD and the cp -R command in the terminal (using the recovery), and done a fresh install of Mavericks. Now, the 1.2 update is still available in the App Store. Should I risk installing it just for the heck of getting rid of the persistent notification (the thunderbolt port isn't being used at all) or should I play it safe and live with the notification? Thank you. Raptor TL;DR: Installing the thunderbolt update 1.2 on 10.8.2 screwed up the OS. Should I attempt installing it on a fresh install of Mavericks?
