How to get Siril log after Siril hangs or crashes?

How can I get a log if Siril hangs (Siril spinning ball) or crashes?

The terminal command

/Applications/Siril.app/Contents/MacOS/siril > ~/Desktop/output.log 2>&1

opens a new instance of Siril and gives the startup log.

I cannot find a log to print out as text in /Applications/Siril.app/Contents/MacOS/siril

Siril-1.4.1
macOS Tahoe 26.2
