Hi Bernhard --

Thanks for reporting. I opened an issue here:

I have downloaded the latest Squeak6.0alpha-21736-64bit for 64bit MacOS:
http://files.squeak.org/6.0alpha/Squeak6.0alpha-21736-64bit/Squeak6.0alpha-21736-64bit-202204190959-macOS.dmg [http://files.squeak.org/6.0alpha/Squeak6.0alpha-21736-64bit/Squeak6.0alpha-21736-64bit-202204190959-macOS.dmg]

I extracted it to a folder and copied the image, changes, and sources files from inside the package to that same folder. I dragged the image onto the app. Squeak opened. I opened a Transcript and saved and quit the image.

I start the image from the command line with a startup script file which just prints something to the command line:
./Squeak6.0alpha-21736-64bit.app/Contents/MacOS/Squeak Squeak6.0alpha-21736-64bit.image latest.st [http://latest.st]

The file latest.st [http://latest.st] is in the same folder and just contains this:
Transcript cr; show: 'execute latest.st [http://latest.st]‘

Instead of printing to the Transcript a notifier with the following error message opens:
Cannot start a second instance of Squeak\with the image „latest.st [http://latest.st]“ because the VM is configured as singleton application.

Any idea why?
