Great news the Mac version is imminent. I've used PTE for about 8 years on my 2012 27" iMac, High Sierra 10.13.6 with 8GB RAM, under Parallels. Running such a superb program under Windows7/Parallels is really cumbersome and stretches my computer. I can't wait for the Mac version to be up and running and would love to be involved in beta testing.
