Cannot open .dmg install package on macOS Catalina
I just downloaded the installer package on macOS Catalina (10.15.6). Then I double click on the Justinmind_Prototyper_MacOS.dmg file that was downloaded. The OS returns an error that it cannot open the disk image because there is a Resouce busy.
Perhaps the disk image is not compatible with Catalina.
Please advise how to install the application.
