Ignore process serial number argument passed by macOS Gatekeeper.

Ignore process serial number (-psn_...) command line argument passed by macOS Gatekeeper.

PSN is only passed on the first start of the downloaded app (.app bundle with com.apple.quarantine extended file attribute), confuses Godot, causing it to load non-existent project instead of project manager.

Fixes #37713
Probably fixes #37446, fixes #35383 and fixes #36616?

There should be a comment so we know why this was added in the future 🙂

It's really a weird design for macOS to arbitrarily pass arguments to thirdparty processes that are not designed to handle them... I'm sure we're not the only ones to have issues with that (though our argument parsing is particularly bad right now, but we'll get to properly fixing #20000 eventually :)).

Anyway, this is hacky but seems like a good solution for now.

Thanks!

This was the normal way to pass PSN to the Carbon apps (API deprecated in 10.8 and removed in 10.15), probably some of the old code accidentally get into the Gatekeeper.

I'm sure we're not the only ones to have issues with that...

For the reference, it's definitely known issue: Chromium, Qt, Firefox

Cherry-picked for 3.2.2.
