Hallo and Good Afternoon, 

I have a problem with my chitubox software. I had sliced my Objekt and when I want to save it on my Mac a window with the Text "The suffix is not supported. Please ask the device vendor for the relevant suffixplugin" appears and I don't know what to do can you please help me? 

Sorry for my bad English I hope you get it.

Greetings from Germany
