Hello, I've used pribambase on other computers successfully. On my Mac when I try to create a new sprite texture or edit a sprite through blender the addon produces an error. 

The error is related to errno 13 and seems like the addon doesn't have privileges to launch aseprite. 

I will update this post in a few hours with the exact error when I have access to the computer, but thought it might be common enough to just ask.

heyo. i’ve no idea, it works there as far as i am told.

for one, privileges are part of the user running the program, and not anyhow related to the addon. for other, in practice that error usually means trying to execute a wrong file. you can try providing own path to aseprite’s .app file in settings.

anyway you can just launch aseprite normally, press “file > sync” there, and “connect” in blender. same results.
