Which version of OS X / macOS is best for Aperture support in a VM?
In addition to Aperture I've a few legacy apps that I'd like to hold on to. Aperture may more or less work on Mojave, but it's probably a bridge too far. The migration to Lightroom is too difficult to contemplate (esp. metadata and image edit loss) so I have to migrate to Photos.app -- but I'd like to give Apple a bit longer to fix Photos (yeah, probably futile hope).
So I'm considering running Aperture in a Parallels VM. Which version of macOS would be best?
I'm thinking one of:
OS X 10.8 Mountain Lion (Zinfandel) - 25 July 2012
OS X 10.9 Mavericks (Cabernet) - 22 October 2013
OS X 10.10: Yosemite (Syrah) - 16 October 2014
OS X 10.11: El Capitan (Gala) - 30 September 2015
Aperture 3.6, a final update adding compatibility with OS X Yosemite, was released on October 16, 2014. So I'm thinking either Yosemite or Mavericks. I thought Mountain Lion and El Capitan were pretty good, but I can't remember much about Mavericks or Yosemite.
Any opinions on the best choice for Aperture?
