'NSInternalInconsistencyException', reason: 'NSWindow drag regions should only be invalidated on the Main Thread!'

[TimmermanV]

I have built PCem according to the instructions, on macOS Catalina. While the application does start and I can create a configuration using the PCem Configuration Manager, it crashes when I try to start the config. Just before it crashes it's opening a new window which I guess is for the video output of the emulated machine.

Here is the output when I manually try to launch the executable:

Menu item not found: 1403

I commented out the code that updates the window title in runpc. Now it seems to be working fine. (I just tested 1 machine configuration so far and I didn't get any further than "DISK BOOT FAILURE" for now ;-) but that is a good sign)

Hi Tim :)
the boot disk failure probably is because there is no floppy disk/cdrom mounted :) (right click, select image to mount for boot)
btw I'd suggest to use our most recent code branch V17 :)

Yes, I know. :-D (about the disk boot failure) Thanks for telling me about the more recent branch! I wasn't aware of that. Op ma 26 apr. 2021 10:02 schreef Aron Homberg ***@***.***>:
