I’ve just upgraded from an early 2011 Macbook Pro to a new iMac, running El Capitan. (10.11.2)
FCP 7.0.3 has been my workhorse for almost 8 years and whilst I have the Adobe Creative Suite as well – I still prefer FCP. I upgraded my MBP to El Capitan before I bought the iMac.
I used my Time machine backup from my MBP to install all my programs onto the new iMac and part from one niggle – it all works fine.
Only problem is the colour picker doesn’t seem to work. (Using it to set the white colour balance produces a weird colour). But I can just grade by eye anyway. Seems to work OK.
I take the points about using an old, outdated bit of software on a new system – but like some of those in teh forum, it’s what works for me. Hope this helps.
