@Don Richmond, you are successfully using Catalina with your GSR34M?
I have just got me a GsR24M and I have purchased a Mac mini with Catalina OS.
Did you run Sierra before and then installed the A&H latest software before upgrading to Catalina?
I am concerned my GS + Mac mini will not work with Catalina, since I cannot go back to High Sierra to install the A&H software…
Thanks
