When using Minecraft 1.9 or later on any version of Mac OSX, Open to LAN yields no results when Scanning for games on local network.

This happens ONLY on WIFI, when all Mac computers wired on ethernet, LAN servers can be found.

Works on all versions 1.8.9 and earlier.

Direct Connect works

I have tried:

• quitting and restarting Minecraft
• restarting computer
• power cycling modem and router
• re-installing Minecraft on all computers.
• Confirmed Firewall is OFF
• turned firewall ON on all computers and then turned OFF
• restarted all computers again
• all this, no love

I have spent hours searching the internet for a solution and have only found the Direct Connect option. This is not practical as each time the user opens the single player game to LAN, the Port changes. So even if the IPv4 address is static, new information has to be provided to every other player each time the fame is restarted.
