I bought the new MBP 2018 right after it came out and have enjoyed learning how to use it after a lifetime of Windows products. However, the one thing I can't figure out to save my life is how to set the network to Private or even how to create a home network. Used to be pretty straight-forward in Windows but not-so-much on this MBP. And yes, I've Googled it until I'm blue in the face. Surely it can't be that hard. This MB is showing WORKGROUP with no other options. Any help would be greatly appreciated.
