NiMate crash to black screen

Hello!
I have a permanent interactive installation using NiMate (2.14) + Isadora (3.02) that is consistently crashing to a black screen after running a day or so. It looks like Isadora is still running but NiMate is not.
The project is on a mac mini running High Sierra 10.13.6, 2.6G i5

I’ve had excellent experiences running a similar projejct w Isadora 2.0 + NiMate1 a few years back + I can’t figure out what the problem is here. I can send crash reports if that is helpful
Thanks!
Ruth

Could you submit a crash report?

The first thing to do is to disable GPU Texture Transfer in Preferences -> General and see if this causes the problem. If you’re using Syphon feeds with Isadora this will remove those as the same GPU features are used by Syphon.
