How can I load/save minecraft worlds to a USB drive, on a Mac?
There are a number of answers about running all of Minecraft and MineOS from a USB drive. Here I'm asking about only loading/saving worlds from the USB stick. Running all of Minecraft from USB is too slow. I can copy the worlds from USB to the computer, play, then copy the files back to USB, but this is error prone.
So: can I insert a USB stick into an OSX Computer running Minecraft, and play worlds directly from that device?
A tutorial that does not answer the question is: http://minecraft.gamepedia.com/Tutorials/Playing_and_saving_Minecraft_on_a_thumb_drive#Mac Other tutorials describe using DropBox and symbolic links, but that is not applicable for use on a guest computer you don't own.
Best Answer
You should create a symbolic link between the two folders (saves and the saves folder on your USB drive). Instructions on doing this with your Minecraft worlds are shown at http://minecraft.gamepedia.com/Tutorials/Saved_data_Dropbox_guide_saves_only. Instead of using dropbox as your destination folder however, you can use a folder on your USB drive. The quote below from the Minecraft Wiki (link above) shows you how to do this on Mac OS using the terminal.
ln -s ~/Dropbox/Minecraft/saves ~/Library/Application\ Support/minecraft/saves
Replace ~/Dropbox/Minecraft/saves with the destination folder.
