MacRhino 8 crashes with properties command

Rhino Rhino for Mac
1

After trying many things with no luck, I reset Rhino to factory settings and now get this at start-up

Error occurred loading plug-in

Details:

panelType must be derived from MonoMac.AppKit.NSView or Eto.Forms.Controls (Parameter ‘type’)

Now Rhinoforum thinks I am a new user, so cannot upload sysingo file. What is up with that?

have you tried disabling 3rd party plugins?

3

Disabling plugins that “did not ship with Rhino” stops the crash (so far). Then added back in the McNeal plugins that did not ship - still working fine. But, still have an annoying plugin loading error at startup: (Maybe artifact of my obsolete Intel MacBook Pro???)

Error occurred loading plug-in

Details:

panelType must be derived from MonoMac.AppKit.NSView or Eto.Forms.Controls (Parameter ‘type’)

Are you running this plugin? GH_CMD / Monkey on Food4Rhino (Monkey | Food4Rhino)

5

No. Should I be?

6

I noticed a “grasshoppercmd v6.0” package installed, which apparently provides a similar capability as “monkey”. I uninstalled that package and the local error went away.

Does that make sense?

… “load error”
