Latest = fully working - if a feature doesn't work and actually requires you to upgrade OS I wouldn't count it as "latest"

 

I'm keeping mine at 10.5 either way.

 

10.5.1 is the last Mojave-compatible version.
10.6.x all require Catalina, and 10.7.x all require Big Sur.

 

I've heard there was a way to patch the Catalina versions and make them run on Mojave, that's why I'm asking

 

Nope. Logic links against system frameworks, you can't just tweak a plist and expect it to run.

Perhaps you're confusing this with patching *Mojave*, to let Mojave run on older, non-Metal machines only capable of running Catalina.

Which is possible - I did it. However, certain areas of Logic *require* Metal, and will crash without it, so even if you patch Mojave and get it running on an old machine, 10.5.x is not stable on it.

10.7 has required Monterey since I think 10.7.4 (which wasn't released at the time I posted the above info - a year ago - which was correct at the time). So yes, from (iirc) 10.7.4, you need Monterey 12.3+ as a minimum.

But it wasn't 10.7.8 where the system requirements changed, it was earlier.
