That is so crazy! As stated before, I am not new at this. Have been editing FCP since version 1 with my Mac G4! I uninstalled, reinstalled, had Apple send me a new machine. Nothing works! Same footage on an older Mac Pro works beautifully with same internal hardware, 3rd party plugins! Does anyone have these same issues? It is NOT the video card as I swapped with my 2009 generation video card 4870. Apple is stumped. I am stumped. The arrogant FCP guys tell me the same thing every time. Uninstall your 3rd party software. Did that too. Nada. What is up with this new machine. Apple – now that your stock is at over 300, shift your focus from the ipad slightly to Pro Apps! We need you OR we are going to flock to AVID. Please does anybody have any thoughts besides uninstalling, cache, preferences?
