Macos V15 Beta Crash upon Start #99232

https://thebrain.zendesk.com/agent/tickets/99232

Hello,

Thank you for reporting this, and for including your Mac details.

Since TheBrain 15 is crashing immediately on launch, the next step is to gather a bit more information so we can see whether it is a startup state issue, a compatibility issue, or something else.

Could you please send the following:

1. The exact TheBrain 15 version you installed (for example, 15.0.xx.0) and whether you installed it from the .dmg on our website.
2. What happens right before it crashes, for example does the window appear briefly, does it stay on the splash screen, or does it close instantly. A screenshot is fine.
3. A fresh Output.log captured right after a launch attempt:
   • Quit TheBrain
   • In Finder, click Go → Go to Folder…
   • Paste:
   • ~/.TheBrain/v9/Logs
   • Attach Output.log

If macOS also generates a crash report prompt, please include that report as well.

Once I have those, I can advise the safest next step.

Best regards,

John
