I have a First generation Mac Pro with 4 internal discs 1 with 10.5.8 one with 10.6.8 and one with 10.7.3 I have never been able to start Final Cut from the 10.7 disc even though I formatted the disc before installing 10.6 then upgraded to 10.7. But Final Cut did run on on my 10.5 and 10.6 disc. Now I am only able to run it on my 10.5 disc. as it crashes in start up process when running 10.6.8. The weird thing though is that when Starting final cut via spotlight in 10.5 it chooses the version of Final Cut that is in the application folder on my 10.6.8 startup disc and it starts with out a problem. Does any one have an idea why an application that will not start up in 10.6 will start up in 10.5?
