Most stable OS for Aperture 3.6?
I'd like to get some opinions as to what people believe to be the version of Mac OS that is best suited to running Aperture. Though we know Aperture runs on High Sierra, I would not necessarily say that is is 100% stable, as certain features are pretty flakey. When I buy my next Mac I'll be locked in to High Sierra (or Mojave, depending on when I buy), without the option of going back to an earlier version of the OS. I plan on keeping my current iMac (27" late 2012, maxed out) as a machine dedicated to Aperture with an OS version I'll never update.
As an aside, I currently have my Mac setup to boot into any one of several versions of the OS depending on what I'm doing. I'm usually running High Sierra and do find Aperture mostly stable on that OS, though I switch over to Sierra when I need to do significant brushing.
Is there a nice matrix that maps OS to Aperture features?
Thoughts?
