Hi Vasily,
I've got a new Catalina mac, and managed to get Ambience reverb installed and running fine. It doesn't have the fancy GUI though. I did it using some quarantine
Terminal commands I found (maybe on this forum).
First put the plugin file (
Ambience.component) into a new folder on the Desktop. Then open Terminal.
Type:
and drag your folder onto the Terminal window (there must be a space after "cd").
Then:
Code:
sudo xattr com.apple.quarantine *
It will ask you to type your password (which you won't see on the screen).
When done, drag the plugin file to the
Plug-Ins/Components folder. After that, for some reason, you have to log out of your mac before the plugin gets picked up by the system.
Hope you get it to work. :-)
