I have a late 2006 iMac running lion. I also have Final Cut Express loaded in 2006. After 8 years I've had to wipe the hard drive and reinstall the OS. The result is that FCE 3.5 will not reinstall. I've made the decision to finally upgrade the hardware and purchase FC Pro X. What I'm worried about is whether this version will run my FCE projects. One is ongoing with several hours of interviews in the scratch and half an hour edited. Don't really want to have to upload all the video again (I still use tape) and start over. Any information/ideas would be most welcome.
