Rhino 6: Fonts Unavailable

Struggling mainly with Helvetica Neue. This font on mac shows up in the text editor just fine right now. But when I install the font on windows, text editor won´t see it. If I, on the other hand, Install Helvetica NeueLT STD on windows, it partly work on windows (I can see 6 out of 8 fonts in the family), but not on mac. So I am a bit in a dead end. Don’t know if there is any bottle-neck when it comes to some fonts or…Do you have any ideas?

I was pointing it out here Font family / helvetica not supported?
