We have an installer which installs various things - a kext, a deamon, some libraries, and a mac app into /Applications.
When I run on Catalina, I get: "This package is incompatible with thie version of macOS. The package is trying to install content to the system volume".
If I customize the install to omit the mac app, it installs everything else fine.
Installer is notarized and works fine on 10.14.
Is there some limitation in 10.15 on installing apps into /Applications? I'm not sure why it's talking about the system volume, I'm definitely not trying to install anything into /System.
Thanks,
