You need to have java 6 or later installed on your mac for a minecraft server jar to open correctly. If this doesn't work you can use a terminal command to run the jar.
To run a Minecraft Server you will need to download the server software (See links below) and then enter the command... java -cp minecraft-server.jar com.mojang.minecraft.server.MinecraftServer ...into the Terminal. The Read Me file that comes with the Server download explains how to configure the server to your particular needs.
You should be able to go onto any bodys server thats hosted on a Mac or Windows, with any Mac or Windows machine. Minecraft is cross platform compatible. (Mac and Windows). You just need their "outside" IP address.
You can place blocks but not make them.
