I’ll just chime in here with my recent experiences re: FCP2 upgrade. After performing an upgrade on three nearly identical systems (Dual 2.7GHz G5, 4GB DDR SDRAM, Nvidia 5200 or ATI? card, Kona2) we have begun to experience random crashing of FCP to desktop with the error message “FCP unexpectedly quit…” No hardware changes were made during the upgrades.
Calls to my local support engineer indicate there may be general stability issues – expect patches in Septemeber for IBC. I’ve also done a “Send Feedback” to Apple regarding our issues and recommend anyone else experiencing different behavior after the upgrade to do the same. FCP v 6.0.1, OSX v.10.4.10, QT v.7.2
