Unhandled Exception

Hello, I have someone who was using one of my scripts on an Intel based MAC and it hard crashed Siril on a particular line which was running a Pixelmath command. He said that he could execute the problem line on the command line with no problem and also no one else has reported this.

The line in question is: pm "($result_Ha$*0.4)+($result_OIII$*0.6)"

Is there any sort of syntax error in it?

Hello. First are you sure he’s using last Siril version?

1.2.1 and Intel Mac running MacOS Sonoma 14.4

Without more details, it’s difficult to answer.
We have written a documentation page explaining how to send us details. Maybe this will help.
