What OS X do you use?
I can’t open it on Yosemite :frowning:

In this video it’s 10.6.8 (Snow Leopard), on my other system I use Mavericks and I’ll stay away from Yosemite as long as I can, there is nothing audio-wise in there which improves audio work, so on computers dedicated to sound design and music I’d rather stay on stable and working systems as long as possible.
