Get the Dark Mode Boot Screen on Your Pre-2011 Mac Running Yosemite

When Yosemite was released, a more detailed boot screen came to your Mac. So now, just like on Apple's mobile devices, you will see a loading bar telling you how far into the startup process you are. Apple also decided to add a black version of this boot screen to newer Macs, leaving those of us who purchased a computer before 2011 out of the loop.

I have always been a fan of "more" in terms of aesthetic changes, so when I came across the work of Manic Harmonic and his method of enabling the black boot screen on any Mac, I knew I had to have it on all of my devices.

Originally this process required you to modify some system files using a hex editor, but thanks to w0lfschild and some Apple script magic, we now have an automated way to get this dark boot screen with minimal effort.

Know that this hack has the potential to really screw with your machine if you aren't careful, so use your preferred backup software to make a fail-safe, and follow the instructions carefully.

Step 1: Download & Unzip Script

Since this mod would never be hosted on the Mac App Store, you will need to download the DarkBoot archive and unzip it to your Mac's desktop. You should also move the DarkBoot.command file within the unzipped folder to your desktop to make the next few commands easier.

Step 2: Make the Script Executable

Before the script can function properly, it will need to be made executable. To do this, open up Terminal and type the following commands:

  • cd Desktop
  • chmod 755 DarkBoot.command

Now close Terminal and your script will be all set.

Step 3: Run Command

You can run the script by double-clicking the Darkboot.command file. It will ask for your password in Terminal before it proceeds, so input it when prompted.

Step 4: Reboot Your Mac

That's pretty much all there is to it. To see the change take effect, you will need to reboot your device two times—not just once.

Step 5: Going Back to Normal (Optional)

Note that this will not work with devices running anything other than Yosemite, so if you ever downgrade back to Mavericks, you will need to revert back to the original boot screen.

The script made a backup of your original boot.efi file before tweaking it and placed it in /System/Library/CoreServices/efi_backups/. Find your original file, place it on your desktop, then rename it to "boot.efi" (without quotes) and run the following five commands in Terminal:

  • sudo chflags nouchg /System/Library/CoreServices/boot.efi
  • copy the original backup to /System/Library/CoreServices/boot.efi
  • sudo chmod 644 /System/Library/CoreServices/boot.efi
  • sudo chown root:wheel /System/Library/CoreServices/boot.efi
  • sudo chflags uchg /System/Library/CoreServices/boot.efi

Future Updates

It is possible that a future update to Yosemite will revert you back to the normal boot screen, but as of right now, it is compatible on 10.10 and 10.10.1 versions. I will also be sure to update this guide with the newest version of the script to avoid incompatibility issues.

Until then, enjoy your new dark boot screen, and let us know what you think of it in the comment section below.


it does not work for 10.10.3 when i try it brings up disk utility on boot

Yes, don't try this with 10.10.3, it will make your system unbootable. ...would be nice if the the developer of this hack could check this.
