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: Other tutorials describe using DropBox and symbolic links, but that is not applicable for use on a guest computer you don't own.

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 . 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.
you can actuely save a World in a diffrent place (cloud, USB, etc) by going into your minecraft "Saves" map and Copy the folder which is the world you wanna save but to use it you need to set it back into the "Saves" map of your minecraft or else it wont work
1on the finder(or you can check on the search bar) you go to library than go to application support than navigate to .minecraft folder and find the save folder saves and the world should be there and you can either copy it or move it to the usb.
