Content Cache (baking) Component not working on Mac

Grasshopper
1

Hi guys,

Last week, I tried to use the Content Cache component in Grasshopper on a Mac, but it didn’t work.

I am running Rhino 8.26.25 (2025-12-03).

I get this “instance error”:

So please upload what your file(s) so we can check if it is in the context.

Hi @Eef_Weenink ! Thanks for taking the time.

Here is a test file. I notice that the Content Cache component shows the same warning even if nothing is connected to it.

No issue here. Let’s isolate from other GH plugins by starting grasshopper via the command line GrasshopperLoadOneByOne, saying no to suspect 3rd party plugins (or move out of the gh folder for testing)

No errors here. When I push the button “Push” I get an nice Baked cylinder.

Issue found!!

One of my custom display mode names had a space at the front: “ __Material”. I removed the custom display entirely from Rhino, and the baking component works now!

I had dismissed this other warning I was getting when starting Rhino:

I ran the warning via Claude, and it explained this strange error!
