os x 10.6.8 software updates restart just freezes

First, I googled around and discovered I wasn’t alone, there’s a large thread on Apple Discussion Boards that has over 350 replies by MacBook Air 11″ owners complaining of the exact same problem. In the process of troubleshooting, I discovered a few things. Now I’ll talk about the problem a bit and how I arrived at this. 99% of the time it’s probably not necessary, and I can’t explain why it is here, but it solved the wake from sleep problem immediately. Now you might say my situation is unique because My MacBook Air dual boots between Lion and Snow Leopard, but upon looking at some friends Macs I discovered that even in a single boot setup, a startup disk is rarely selected.

Maybe it’s just an issue with things being loaded from RAM and Mac OS X knowing where to get the data from, I don’t know. Say what? The MacBook Air isn’t booting though, it’s waking from sleep, why would this matter?

Select the startup disk of the OS you are using (in my case, Mac OS X 10.6.7).

Launch “System Preferences” from the Apple menu.

If you don’t know how to do that, here it is: Select a Startup Disk in System Preferences!
