Hello,
I wonder anyone experiences the same problem. I tried to run the documentation example but not working. Basic Example
It is as if MeshConnectivityGraph command does not exist, telling from the way it is highlighted.
(autocomplete works)
I am running Mathematica 12.1 on OS X 10.15.4
Best,

It works fine on my computer, although I am using Windows 10. Try restarting the kernel and re-evaluate. Otherwise it might be an OS X based Mathematica issue
IGraph/M has had IGMeshCellAdjacencyGraph long before MeshConnectivityGraph was introduced. It works in Mathematica 10.0 or later.
Cool. I am already using IGraph/M for one of my side projects. Works like a charm 
A wonderful package! It works great, I will keep playing with it.
If the builtin does not work I would suggest send a bug report to support@wolfram.com. this way they can fix if it is an OS related issue
@Ali Hashmi, thanks for the advice. Maybe it’s an OS X issue, restarting the kernel does not help. MeshConnectivityGraph
remains blue as if it is not a built-in command.
Thanks!
But if you are using 12.1, then it should be a builtin command? It was introduced in 12.1. Please contact support.
@SY Yoon:
Can you post the output of evaluating $Version?
Also, can you try disabling the suggestions bar (it’s in Preferences → Interface) and restarting Mathematica? In older versions there was a bug where the suggestions bar somehow caused some symbols to become undefined. I assume it’s much more robust in recent versions, but it’s worth a try.
BTW it’s not a macOS issue. It works perfectly fine for me on macOS.
@Szabolcs Horvat Bingo! yep, I didn’t realize the kernel was set on WolframEngine(Jupyter)
until checking $Version to produce 12.0. Now it works after switching to Local, thanks!
