In the last couple of days, as many have found out, there is an update out for Apple OS X Lion’s Thunderbolt application. Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices through a single, compact port. It sets new standards for speed, flexibility, and simplicity. And it’s on MacBook Air, MacBook Pro, iMac, and Mac mini.
This is great and all, but with this new update, your computer will most likely crash and burn (like mine did). There is a solution though…so be hopeful! BEFORE YOU UPDATE your computer, always make sure you back up your data…I cannot stress this enough. If you have already updated and not backed up, there is hope.
When you get the gibberish (also called the kernel <panic>) your screen will tell you to simply restart your computer. You can do this, but it won’t fix a thing. What you can do is take the following steps to repair your computer, safely.
The reinstall will take about an hour and half then put you into 10.7.3. It will retain all your files and prefs so nothing will be lost. Then go to your software update (top left apple dropdown) and you will be offered 10.7.4 and a few other updates; go ahead and do those. You will then be back where you were, and with a brand spanking new system. Going to software update again will offer you Thunderbolt and iPhoto. DON’T UPGRADE THOSE! Simply wait for Apple to come out with a fix.
