When I drag and drop the wrapper on the desktop, I found 5 folders ( Drive_C, Logs, RabbitHole, ROMs and WinUAE ) whit the small arrow of the alias elements and the folder Contents without arrow.
So I copied the files inside Contents>Resources>drive_c.
All the files are in the correct folders.
But no way to start app in OS X Catalina.
UPDATE: After some tests, now Wineskin opens when I launch Amikit, with 3 options: Install Software, Set Screen Options and Advanced. No idea if this is the right way (no mention in instructions) but now I don't know how to proceed.
Sorry, probably I'm doing wrong something.
