Now back to the subject (1. (see above))
The download page on rhino3d.com now works in German and no longer produces a server error.
However, I did not receive a license code for Rhino6WIPMac.
As I learned from this post, I am supposed to obtain a license key in an email.
Here is a screenshot of the email I received from @brian.
I guess you guys might not be able to read German but should agree with me that there is no license key in this email.
When I compare this to an email from @Brian for a Rhino6Test for Windows (expired) earlier this year, I get the feeling that something is missing in the Rhino6Mac email.
Is it me? Am I overlooking something?
I know you guys are dealing with a complex setup where things might go wrong from time to time and try to be helpful.
At the same time, I’d love to get my hands on Rhino6WIP for Mac 
Best, Frank
