I have a Mac mini 2014, running macOS Sierra from a SSD drive, and using an Apple Keyboard M9034 D/A.

Since I replaced the rotational hard drive (HDD) with an SSD, I do not see the Apple logo on the screen to show it's loading.

The start up shortcuts below do not work:

⇧ Shift Start up in Safe Mode;

⌥ Option (alt) Start up to Startup Manager;

⌘ CommandS Start up in single-user mode;

⌘ Command R - Start up from macOS Recvery

⌥ Option (alt)⌘ Command R Start up from macOS Recovery over the Internet.

The only combination that works is the PRAM reset:


  • Already tried with 3 different keyboards.

  • Installed a complete fresh copy of the Operating System.

  • macOS Recovery only works if the system has some kind of issue, meaning if the boot does not work.

C Start up from a bootable USB only works if there is not an operating system on the hard drive.

Anyone have suggestions to try?

  • You should edit that information into your question, don't just post a comment with it.

  • What kind of display and cable are you using? What exactly happens if you press and hold option/alt after pressing the power button? Commented Apr 20, 2017 at 23:45
  • @Kevin Grabher, I have two monitors connected to the Mac mini, one using Hdmi and the other APPLE MB572Z/B Mini DisplayPort VGA adapter, pressing option doesn't do anything, both display don't receive any signal, the same happens with cmd+option R, only black screen... I managed to boot on recovery mode with success rate of 1 in many tries. At the moment I am trying to install El Capitan in another disk, to see if it works, but didn't manage yet to boot from USB installation disc. Commented Apr 21, 2017 at 17:59

Thanks Kevin Grabher,

You gave me the solution....

I tried booting the system using only the HDMI monitor, removed the Mini DisplayPort VGA adaprter.

Using only the HDMI cable and monitor, everything works.
