I'm sure if you're a Mac user you know Catalina has dropped but , you need to know that FG decided not to to upgrade classic FG to work on a 64 bit operating system. After upgrading to Catalina, I figured out Fantasy Grounds was no longer working and I reached out to the developers. They apologized but said that my choices would be to create a new partition with an older version of the operating system, run a dual boot with a windows machine or basically wait for and buy their new application FG Unity.
Unfortunately, their Kickstarter for their new platform has ended, so you can only guess what that means. :cry:
So... if you want to continue using the application DO NOT UPGRADE or it will cause mini-crashes on your computer and will no longer work.
