"Press and hold the Power button for 10 seconds, release, and then press it again. If your Mac got stuck in a sleeping state it shouldn't have been in, this will completely power down the Mac and start it up again. Sometimes this is all you'll need to do to fix a Mac that won't boot.\nIf you have any peripherals physically connected to your Mac, including USB hubs and drives, remove these first."
