Final Cut Pro project compatibility after MacBook Air macOS update

I have a MacBook Air [M2] and an iMac Pro 2017.


At the moment, both machines are running Sequoia, and I can edit the same FCP 12.3 project on each.


Convenient for small screen stuff on the laptop and more advanced, dual display, stuff on the iMac.


If I update the MacBook Air to either macOS 26 or 27, will I run into compatibility issues when trying to edit FCP 12.3 projects on both machines?


I did a web search to check this out and got completely befuddled by the AI results that always seem to come up near the top these days.


I realise the iMac is Intel, and MacBook Silicon, and that there may be compatibility issues for apps with Intel code going forward [i.e. they won't work at all once Rosetta is deprecated], but this is a separate issue I think?


I love my iMac, [and yes I know it's almost 10 years old!] even though Sequoia is the last compatible macOS it can run. It has a gorgeous screen and is lovely paired with my Apple Studio display.

The iMac Pro was a great machine. I have one, still. But once it hits the wall on macOS updates, that's it. It will limit what you can update the MBA to. Simple as that. Don't let the MBA get FCP versions beyond what the iMac Pro is able to update to safely.

Thanks @BenB
Great suggestion :)
Just wondering how I prevent FCP from updating automatically on the MBA before I've checked the iMac Pro can handle the same update?


Just open the App Store settings and make sure that this is UNchecked:
