As stated on docs.microsoft.com, in order to distribute apps to macOS, they need to be in .pkg format and converted to the .intunemac format. Furthermore the .pkg file needs to be signed with a Apple Developer certificate.
Quote from docs:
The .pkg file must be signed using “Developer ID Installer” certificate, obtained from an Apple Developer account. Only .pkg files may be used to upload macOS LOB apps to Microsoft Intune. Conversion of other formats, such as .dmg to .pkg is not supported.
But what if we need to distribute an app there’s is not in the AppStore or is not in a signed .pkg file? Then we’ll have to repackage it with a packaging tool. I’m using an app called packages. Let me show it and explain.
