Can I run iMovie 10 and iMovie '11 at the same time?
I have a MacBook Pro (see info in screen shot below) on which I'm currently running iMovie 10. When I upgraded to Yosemite I also upgraded iMovie, but I really prefer the older version, iMovie '11. I have the iLife 11 installation disk and would like to reinstall that version of iMovie so I can use it for the movies I'd created in that version. I know I can update my previous projects to iMovie 10, but I'd like to keep them separate, if possible. I haven't tried to install the older version yet as I wanted to know if I'm going to experience issues trying to run both on one computer. I'd appreciate some advise. Thank you so much.
