Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
Can you tell me the exact name brand and model of the Switch you want to use with your mac.
Hi there and welcome
u can bypass the software and setup the switch directly via Safari.
Make sure your connected to the switch and your network is in a range of 192.168.0.239.
you can check this via the Apple System Preference, Network, and ur IP address will be visible to the right (click on wifi or ethernet depending on how your connected)
You can also see how to do this page 15 of the manual here
Let me know how you go please.
