Running more than one instance of the same PsychoPy on macOS

Trying to run two instances of PsychoPy on the same macOS computer (for ease of building a new version of a similar experiment).

The old trick of opening a terminal and typing:
open -a /Applications/ myold.psyexp

followed by:
open -n -a /Applications/ mynew.psyexp

didn’t work. Is there a workaround?

Do you mean two different versions?


No. The same version.

Cheers, Jon

You can copy and paste components and routines between the two instances.
