I've been running SN Pro 8 on a 2013 MacPro with zero issues, everything works including telescope control.
Today I installed SN Pro 8 on my Mac Laptop, a mid 2010 13" MacBook Pro and the installation went fine and the program loads fine but I'm unable to connect to my telescope. It doesn't show up in the "Connection" pulldown menu. See photos below...
The MacPro is running OS 10.15.7 and the MacBook Pro is running OS 10.13.6 (the most current version of Mac OS it can run). Both are maxed out with memory.
Using the same cable for both
Here's the working MacPro Control setup window
