So, I have been editing on Final Cut Pro 7 for the past million years, and I do not want to upgrade to 10. I bought a new iMac last december (holy God is it good) and was able to install 7 once again via discs that I'd kept. I'm just wondering if in the future I will not be able to install via disc. I edit for fun/ sometimes for a project for someone for money, but mainly for fun, and I really don't want to change software or anything. So, if there is someone who understands the technology better than I do, will I be always able to install 7 on any Mac in the future, as long as I keep these discs? Thank you!
