I was wandering because I thought you used a different script than what I sent. If you only changed the palette it should not make a difference. I am on Linux. Maybe there is a problem with screenshot saving on MacOS. Maybe someone else with a mac could try this. If not, I am in the process of getting a mac laptop, I'll try to remember to try this out when I get my new laptop.
