How to start up your Mac from an external USB storage device Step 1: Turn on your Mac by pressing the power button by choosing Restart in the Apple menu, or restart it if it's already on. Step 2: Press and hold the Option (⌥) key immediately upon hearing the startup chime. Release the key after Startup Manager appears. Startup Manager will scan and list connected drives and volumes that can be booted from. Select your USB installer. Step 3: Highlight the volume you want to use by using your mouse or trackpad, or left and right arrow keys on the keyboard. Step 4: Double-click or press the Return key to boot your Mac from the selected volume. Tip: If there are several USB storage devices connected to your Mac, Startup Manager will only list the ones containing bootable volumes. Tip: If you would like to perform a clean install and erase all date. Select Disk Utility to Format and erase your hard drive before installing again. After formatting your hard drive, exit the Disk utility app and install the OS. Tip: If you have any questions or concerns feel free to reach out to me. Tip: If you receive this message, "This copy of the install OS X El Capitan application can't be verified" your date and time are incorrect. You can set your date and time by connecting to the Wifi and/or going into terminal utility and typing the following command if you are connected to the internet ntpdate -u time.apple.com If you are not connected to the internet use this command to update manually date 0712122318 For that example it would set the date as "July 12 2018 at 12:23" date is in the format [mm][dd]HH]MM[yy]
