I'm thinking of purchasing VM 11.5 to run on my Mac Book Pro with OS High Sierra- don't plan to do the Catalina upgrade. I want to be able to run Storyline 2 ... am familiar with parallels but last I used it on a Mac it was super clunky and created a lot of drag. I'd be interested in others experiences.. I've read it works great for some on Mac if using VM Fusion ... would like to hear experience from the trenches before taking the plunge.. thank you in advance!!
