How to boot a Mac from USB media. Getting your Mac to load from a USB drive is fairly straightforward. Insert the USB boot media into an open USB slot. Press the Power button to turn on your Mac (or Restart your Mac if it’s already on). When you hear the startup chime, press and hold the Option key. Holding that key gives you access to OS X. Now, click on the “Erase” button and the Disk Utility will prepare the USB stick for the next steps you’re going to follow. Disk Utility will let you know when it’s completed the task; once it’s finished, close Disk Utility. Make a Bootable USB Stick. Next, you’re going to head on over to the Mac App Store on a Mac laptop or computer.
