Sadly, this is a real mod, which every player needs if it wants to play on your server. There is a possibility that a plugin has been made for customizable human NPC with a skin changer. But I have no idea if it exists or not.
No. You will need to switch to 1.9 in order to join. Itâs really easy, just hit Edit Profile on the main window and you should see the option to downgrade.
The map or the server? I dunno if the map will work for Macs, since it was built on PCs. The server will be run on PCs, I dunno if it is cross-compatible with Mac.
I think both works on both devices as most servers and maps work for me, owning the Mac version of Minecraft. I guess weâll have to wait until the game night to see.
