MacOS release with GDNative throws validation error. #592

Open SnailBones opened 3 years ago

SnailBones commented 3 years ago

I've released windows and Linux builds for this game, but I'm encountering a unique issue on Mac. The game works fine in the editor, but after export it appears as a blank screen and complains that my .dylib is not valid for use in process using Library Validation: mapped file has no Team ID and is not a platform binary (signed with custom identity or adhoc?)

Here's the start of the log file:

This issue with godot-git-plugin may be related.

Select "disable library validation" entitlement in the export settings, it is required to load libraries with the different signature or no/ad-hoc signature.

Thanks @bruvzg, that worked like a charm! Having this in the documentation would've been helpful.
