macOS 10.14.5 requires apps to be signed and notarized in order to run

OS: macOS 10.14.5
Version: all

Running a release version on macOS 10.14.5 results in an error:
“OpenRCT2.app” can’t be opened because it is from an unidentified developer.

The recent Versions of macOS require apps to be signed and notarized.
This should be included in the release versions.

You can still right-click an app bundle in Finder and select 'Open' to work around this — macOS will remember the setting.

However, you're right, and this will be more tightly enforced as of macOS 10.15. It is something we will have to solve.

Oh, i did not know that workaround. Nifty, thanks.
Building it oneself also bypasses the issue.

Is it even possible to get a program notarised if you don't have an apple id.

No, it is not, but I think the free developer ID suffices.
