Only the lite version works in Aseprite v1.2.16.3, for some reason the normal version doesn't seem to draw any boxes in that version...
Can you check the Color Mode of your document? It should be in RGBA mode(I've tested both scripts in 1.2.16.3 and seems like everything works on macOS)
I just recheck again and both the lite and normal version of the script works as intended now. I am not sure why it didn't work the first time when I tried to run the script though.
Anyway, thank you for such an amazing plugin. :)
Glad to hear :)
Hope you'll find this script useful!
