Line MAT doesn't Render

I am trying to simply render a circle with Line Mat but it basically goes dark and it doesn’t show anything. I have a MacBook Pro 2014, 2.2 GHz Intel Core i7, Intel Iris Pro 1536 MB.
Touch Designer version 2019.3703030 Jan,
Please help!

Line MAT.toe (3.8 KB)

I use macOS High Sierra version 10.13.6

Hmm. Opening your file on my 10.14.5 Mac Pro, this seems to render just fine for me. It looks like you’re doing it right. Anybody have other ideas?

There are some reported issues with macOS Intel GPUs affecting the Line MAT. Can you post a screenshot of your ‘About the Mac’ so we can see the full GPU specs?

Thanks Ben,

Oh, I was expecting a model number but they just call it ‘Iris Pro’ :confused:

This is what I can read from system report
