Q: How do I put 10.6 Snow Leopard on thumb drive

Hi CowsInTrees,

I'm a bit unclear on what you are looking to do with this external installation. If you are having issues selecting your USB thumb drive as a destination when booted to your 10.6 install disks, you may find the this article helpful:

You may also find the following article useful, which explains the process for more recent versions of OS X, using Recovery (introduced in 10.7) and the Mac App Store:
