Steam version doesn't detect Godot being open past the launcher

[yukonmakesgames]

Tested versions

• Reproducible in Godot v4.5.stable.official [876b290].
• I cannot test at the moment, but my memory serves that this was not present in v4.4.

System information

Godot v4.5.stable - macOS Tahoe (26.0.1) - Multi-window, 1 monitor - OpenGL 3 (Compatibility) - Apple M3 Pro - Apple M3 Pro (11 threads) - 18.00 GiB memory

Issue description

After launching into a project, Steam loses connection to Godot, preventing hours being tracked.

Steps to reproduce

1. Launch Godot v4.5.stable.official [876b290] through the Steam client.
2. Open a project.

Minimal reproduction project (MRP)

N/A, can be recreated with any project. Will provide this if needed.

I haven't double checked but a priori it should be the expected Steam-enabled build for 4.5.

At least at some point it was working. Might need the same extra code as we use on Window (it should support all platforms, but was only used on Windows), I'll check it.

I can confirm the issue, and enabling #79126 seems to work:

• build with steamapi=yes
• copy libsteam_api.dylib to the Frameworks subfolder of the .app bundle.
• add steam_appid.txt in the same folder as .app bundle.
