App works only if dmg is mounted

[bartek-galazka]

Recap:

• Downloaded the DMG release
• Mounted DMG
• Installed it on macOS 12.6 by putting .app in Application folder
• Unmounted DMG
• Tried to open - nothing happened just tray icon seen for "0.00001 s" and disapeared
• Nothing works in background
• The ~/Library/Application Support/Syncthing/syncthing.log syncthing daemon logfile is NOT created

Works only if dmg is mounted

Hi @bartek-galazka, thanks for the report. Could you check the following:

• Which version are you using?
• Execute defaults read com.github.xor-gate.syncthing-macosx Executable from Terminal.app (console)

My iMac is running still on macOS 12.7.6 so I have a similair setup.

Check for Quarantine Flag

macOS sometimes adds a quarantine flag when downloading apps from the internet, preventing the app from launching properly.

To check for the quarantine flag, run the following command in Terminal:
xattr -lr /Applications/<YourApp>.app

If you see com.apple.quarantine in the output, remove the quarantine flag using:
sudo xattr -dr com.apple.quarantine /Applications/<YourApp>.app

Gatekeeper and App Verification

Sometimes macOS Gatekeeper blocks apps from unknown developers.
Try opening the app by right-clicking the app in /Applications and selecting Open. This often forces Gatekeeper to bypass the security warning.
You can also check System Preferences → Security & Privacy → General to allow the app to be opened if a warning is listed

I did this. Still doesn't work. But I still see many other things in the output like this:

Maybe this is the reason?

Not the case, that was the first thing I have checked :)
