<<<OS X disk quit half-way through indicating an error,>>>
And, of course, we'd give anything to know what that error was.......
<<< is the reason that Quicktime and FCP are not recognizing the Sony DSR-20?>>>
That's what's so darn much fun about this. You don't kow. Once the Operating System install fails, everything oddball that happens after that could be a result.
Everything in the machine is standing on the OSX kernel. If it's damaged, that's a big problem.
You do own the OSX license, right? Borrow somebody elses and see if that installs. I don't think the licenses are serialized.
