...but I see very few posts offering this very simple piece of advice to people who find the USB they made isnt working.


the program itself is VERY simple to use, you simply select the USB key you want to use (must be 8GB or bigger) and then point the program to the installer .app you want it to use, then just click 'create'

simple enough, but if the installer .app you point it to isn't in the applications folder often the USB key you make wont work as it should.


I tried making an installer key with the .app on a network drive and on the desktop, and on both occasions it wouldn't work when I tried to boot from it.
