Answer to "My MacBook won't boot, no start chime, just the DVD spinning sound."It's now 2018, almost 3 years after the last comment here, and I just stumbled upon this thread while trying to rescue my 2010 MacBook Pro. I rebooted in recovery mode, wiped the drive, tried to reinstall the OS, and nothing would get me past the "black screen with no chime" phenomenon. Incredibly, when I booted while holding down eject, the display came alive again and the chime sounded and I'm now happily reinstalling High Sierra on this old machine. I haven't seen the "hold eject" solution anywhere before this, and it just saved me about $2k buying a new Mac. Thanks a ton, and for those wondering, this fix still works!
