Hi, I've been dealing with this issue for quite some time now. The first time I had the issue it was something about the plist and plugins folder if I remember correctly. That was when I had my Apple support they solved it by deleting and moving some files, but can't remember exactly. What happens is when Final Cut Pro 4.5 HD is loading audio filters on startup it just freezes and never opens up. Does anyone know how I can resolve this issue? This is really wrecking my brains!!! Can any please help?
