Thanks Walter, I got it to work by using these commands in Terminal: cd /Applications
sudo chmod -R ug+x X32-Edit.app A little strange that I had to to this to make it work but at least I am running version 4.1 on Catalina.
Hi Yesterday Dec 9th. it was released a new version 4.1 of X32 Edit. I downloaded it today on macOS Catalina 10.15.1 to try it out. But it will not start at all on my computer. Luckily, its possible to download legacy versions so redownloaded and I tried the version 3.2 and there is no such problems. So, something is wrong with 4.1. The message I get is only: The application “X32-Edit” can’t be opened.
