How to define what version of SMB to use when connecting to a SMB share from a MacOS Client

The protocol defined in the URL of your share will tell the MacOS what version of SMB to use.

If you define your path as cifs://YourServerAddress it will use SMB1

if you define your path as smb://YourServerAddress it will use SMB2/3

You may want to use SMB1 if you are experiencing troubles connecting from your MacOS Client to a Cablecast Flex Server running Windows 10.
