Plug-in not installed error message

After launching Rhino I’m getting this error message
3 times in regard to RhinoDLR_Python plug-in
1 time in regard to MaideRhinoPlugin plug-in (Maide Connect has been uninstalled)

How to get rid of this messages?

I should have mentioned that I tried removing and reinstalling Rhino (both just deleting from Applications and using AppZapper, which helps to remove related files) but it didn’t help.

Plug-ins are installed in

~/Library/Application Support/McNeel/Rhinoceros/MacPlugIns
directory. If you delete the subdirectories, everything should work again.

I can’t find both McNeel and Rhinoceros folder under ~/Library/Application Support/ or anywhere else.
Is it possible it is installed differently under Yosemite?

you’re (i assume) not in the ~User library…

the user library is hidden by default since 10.7 iirc…

one way to get to it is:
• click the finder icon in the dock
• at the top of the screen, click the ‘Go’ menu
• press&hold the option key
• notice the item ‘Library’ appears under the go menu.
that’s your user library.

That’s it, thank you!
I seldom use Mac OS and don’t know such secrets… In fact I thought the idea was not to make UI secretes but that was long time ago.

well, i think the idea was apple trying to encourage developers to keep the users out of the folder structures (i.e.- anything associated with an application should be accessible from within the application itself)… in many instances, i’ve seen this working out… it’s not so much keeping UI secrets as it is simplifying the user experience by not expecting them to navigate thousands of folders/paths…

anyway, if you want to unhide the user library, do this:
• in finder, go to your user folder Macintosh HD-> Users-> your user name (it’s the folder with the house icon)
• View menu -> Show View Options (cmmd-J)
• tick the box ‘show library folder’
