Is this in all documents? What are you doing at the time of the crash? More details would help.

Hey Mike. Thanks for the reply.

I worked on two documents today and had no issues with the first. In the second document, the crash occurred when I was trying to drag a measure to copy it to another measure. Oddly, I was doing the same action with the first document but without any issues.

What happens if you use OPT-click to paste the measure?

When I do a right click copy/paste there is no issue but as soon as I attempt to drag copy the program crashes.

This has been a recent issue and started to occur with my previous version of Finale which is what prompted me to upgrade to the latest version. Is there a compatibility issue with Mac Sonoma?

Also, thanks for getting on to my question so quickly.

If this is only happening in the one document, but not in others, I would suspect file corruption. You might try exporting that one doc as XML, and then importing it back in. This often clears a corrupted file. Or, try copying the bad doc, and pasting it into a new one.

Certain builds of Sonoma have problems that affect plug-ins in ways that can cause apps to crash—even if you are not using them in Finale.

If you have not updated to macOS 14.5, you should do so.
