OK… I have been having some huge problems with FCP 7 and Mavericks. We have a TV series we have been editing perfectly for the past 2 years. I (for some stupid reason) decided to upgrade from my Snow Leopard which was just fine to Mavericks. Since I did that one of our files which is large, gives us the “out of memory” error, and crashes always when rendering. I have sent the hard drive and the computer to some local people here in Reno that know Macs and FCP with no answers. At this point I am ready to downgrade back to Snow Leopard. Does anyone else have this issue?
