I made a report for this but it was flagged as not a bug but a technical issue, this is about the game not working as intended for mac computers. Mac players are unable to connect to a LAN world hosted by a PC, but the PC is able to connect to the Mac world and other PC worlds. Mac is also able to connect to other Mac worlds but not PC. This is all java. This has been tested over about 3 different windows computers and 2 Mac computers. I have tested this over 3 networks and it is still an issue.
