Help with kala
Parrallels, or virtualbox.org or VMware are best but require you install windows on that. virtualbox.org is free.
I have a Macbook Pro (2017) and just updated to Catalina. They've worked out the initial bugs and it seems that many other software companies have scrambled appropriately to adjust. However, a few applications, including Kala wouldn't open. I was using Wineskin, which was free, but no longer worked. However, Codeweavers, the Wineskin creators, have a paid for version that works with Catalina. Its called Crossover 19. And, it worked without a hitch for Kala. I was literally up and running within minutes. Crossover 19 has 3 options: a $39.95 1 year license, a $59.95 1 year license and a lifetime license for $499.95. I went with the $59.95, which comes with tech support, as I wasn't sure what type of support I might have needed, but probably could have gone with the $39.95 license. For me, the ease was worth the $40. Posting to share another option that works for Mac users upgrading to Catalina.
