Just downloaded the Charts package and installed on MacBook Pro running Big Sur 11.5 OS. Installed successfully but on trying to run it got a message along the lines of Apple can’t open this application as it can not check it for malware. Software may need updating. Contact provider.
Added the application to the permitted list in Preferences/Privacy/Accessibility but still same message.
Am I missing something here?
BTW, I also installed FMS Manager and that worked fine and even found my X-Plane 11 files.
