“GIMP-2.10.app” can’t be opened because Apple cannot check it for malicious software.
Tried installing the latest version on my iMac Catalina version 10.15.1 and I get the error message “GIMP-2.10.app” can’t be opened because Apple cannot check it for malicious software. I specifically wanted it because I was having problems opening and saving files since my iMac updated to Catalina.
