Not able to add or install NodePit

Hi,

I installed Knime 4.1 in my Mac and have followed all the instructions here: https://nodepit.com/nodepit-for-knime#faq4

First I was not able to install or either view it in the list of extensions or be able to mount it.

I even created an account with NodePit to see if that would resolve the issue, but nothing.

What am I missing?

Any recommendations would be greatly appreciated.

Thanks,

Roberta
