Apple today released QuickTime 7.5.5.
In typical Apple fashion, all they said about this release was: “QuickTime 7.5.5 includes changes that increase reliability, improve application compatibility and enhance security.
“This release is recommended for all QuickTime 7 users.”
My recommendation is to hold off updating to this version of QuickTime until we see if it causes any problems with Final Cut Studio.
