I looked around the internet without any luck. Does anyone know where I can find which versions of OS X support SMBV3? We are migrating our domain to Server 2016 and need this info to know which computers need to be upgraded if need be. Thanks!

"Server Message Block 3 (SMB3) is the default protocol for sharing files in OS X 10.10 or later." https://help.apple.com/deployment/macos/#/ior96b240d12

When you are connected to a share, smbutil statshares -a will show you the smb settings being used including smb version.
