B2M not working on a Mac

[Sherri Law]

Hi,
I am a student learning rendering and in our class our teacher asked us to download B2M and create some texture maps.  I found that it didn't work properly for me - when I initially inputted my image it displayed fine on the cube, as soon as I tried to make any sort of changes it went really weird and when I outputted the maps they also displayed weirdly.
The others in my class didn't seem to have any issues and my tutor suggested it might be a graphics card problem.  Can anyone help me?  I am using a MacOS Mojave 10.14.4, Graphics card: Radeon Pro 555 2GB.
Would love a response asap cos I am working on a project which I need to finish the texturing on asap.
Thankyou very much
Sherri

Hello,

I think I may be having the same issue on my MAC as well. Hoping someone can answer this, I am trying to edit materials but on the 2nd one or after a few edits/adjustments make everything glitches and eventually goes black on the cube and stops working.

I hope someone can help answer this, but glad it is not just my computer.
