Hello I build an application in Xcode for MacOS. But the exported app I cannot open on different Mac systems. I get the message 'The application X can't be opened'. I can only run the application on the Mac where Xcode is installed.
I used different signing certificates: Apple Distribution, Developer ID application (this should be the one), Mac App Distribution.
I archive the application, then use Direct Distribution, then after complished the notary service, I export the app.
There are two ways to distribute Mac apps:
-
Via the App Store, including TestFlight
-
Via direct distribution, using Developer ID signing
It sounds like you want the latter. If so, you need to:
-
Use Product > Archive to create an Xcode archive of your app.
-
Use the Xcode organiser to notarise and export your app.
For general advice on this, see Notarizing macOS software before distribution.
However, a successfully notarisation doesn’t mean that your app will pass Gatekeeper. To see whether it does, I recommend the process described in Testing a Notarised Product.
If that fails, see Resolving Trusted Execution Problems for advice on how to debug it. Specifically, your first step should be the syspolicy_check tool.
Share and Enjoy
