So when Mavericks came out I waited a few days and made sure all the major video editing programs that I use worked in the new OS. They did so I went ahead and upgraded. What I failed to check on was whether my Sonnet Express34 to eSata card would work. And of course it doesn't. (why would it... that would be way to convenient) I contacted Sonnet and they said the issue was only on mid 2010 models. (which is exactly what I have... perfect...) So they said I have two options, either live without the card and use firewire 800 or downgrade back to ML. I'd gladly go back to ML but I have a ton of small video editing related programs and plug-ins (most pre or non-app store) that would be a massive pain to have to find all the key codes and reinstall all of them again. Here's my question, I couldn't simply make a backup either using Time Machine or cloning the drive itself, reinstall OS X and update to ML and then drag and drop all my programs back? Or would I have to reinstall every program and plug-in? I've never had to do something like this so not sure what exactly is possible.
