Pendant support on MacOSX does not work out of the box

[michael-ring]

Just realized that hidapi needs to be installed on MacOSX so thet the pendant works.
I have created a PR in docs to fix this

Did you use the .dmg install package?

If you are running it via a local dev environment, yes you need hidapi installed. But for regular users we embedd hidapi into the install binaries

As I was using the devel branch I did not use the DMG, let me adjust the PR...

Done, feel free to either completely drop the PR or to accept it with the additional explanations
