NO LONGER BEING UPDATED

I've unfortunately gotten rid of my trusty Mac Pro 1,1, and therefore this repo will no longer be updated.

Mac Pro 2006 1,1 El Capitan Upgrades

Upgrades I have completed on the Apple Mac Pro 1,1 in order to get it El Capitan (OS X 10.11) ready along with code, scripts and links to products and utilities.

Install El Capitan from Spare Mac

  • Attach the Mac Pro boot drive to a Mac.
  • Download El Capitan from the App Store on this Mac.
  • Run Disk Utility and wipe the destination drive, making sure to used GUID partition table.
  • Run the El Capitan installer and make sure to select the Mac Pro drive.

Prepare the New Drive

  • Boot from the new El Capitan drive in restore mode with cmd+R
  • Run terminal app
  • type csrutil disable; reboot (this reboots the Mac)
  • Once booted, download the post-install script
  • Run the script to fix permissions on boot.efi
  • The script will also Replace CoreServices and /User/boot/32 with the new Boot.efi

Install Nvidia Drivers (If Needed)

You can find the latest version of Nvidia drivers for your specific OS X version here

Migrate the Drive

  • Shut down the computer you are using to make the drive
  • Insert the El Capitan drive in your Mac Pro 1,1 (2006)
  • Boot the Mac
  • You will hear it chime twice, this means you've done your job!
  • If all goes well, you'll see it boot (if not, make sure you've used GUID partition type - this happened to me :) )
  • If you're using a PC graphics card, it might take 2 minutes to boot up to the login screen
