Update to 10.11.3 causing problems #9

Open mtroute opened 8 years ago

mtroute commented 8 years ago

Used the boot.efi with prepackaged 10.11 installer, worked fine on MacPro 1,1. System updated to 10.11.3 and as expected boot failed. tried fresh install with 10.11 and now hangs just after boot, never finishing completely. Any thoughts or expirences?

That happened to me as well. I have a Mac Pro 2,1. I found that in my case, the 2nd of these 3 was the one that needed to be cahnged.

Basically here is what to look for.

  1. Type into Terminal defaults write com.apple.finder AppleShowAllFiles YES to reveal the hidden .dot files among others. Type killall Finder to implement the reveal in Finder.
  2. Inspect these 3 "boot.efi"s

/.IABootFiles/boot.efi /usr/standalone/i386/boot.efi /System /Library/CoreServices/boot.efi

  1. If you want to, hide the .dot files with defaults write com.apple.finder AppleShowAllFiles NO and killall Finder.

Excellent, I will try that when I get back home. I was unaware of the 3rd boot.efi in IABootFiles. Thanks for the information. I will update if it works

There are two methods:

  1. Create a bootable USB OS X El Capitan installer. On this USB stick, replace boot.efi in 3 places and include board ID in PlatformSupport.plist. Although this method makes the USB stick bootable on the MacPro 1,1 and the installatiion process can start, I ran into the same problem as reported by @mtroute. The compulsory reboot failed during installation.
  2. Find or create a bootable OS X El Capitan system hard disk drive. On this HDD, replace boot.efi and modify PlatformSupport.plist to include board ID of the MacPro 1,1. Transfer this HDD to the target MacPro 1,1 and boot from this device straight into OS X El Capitan. This method is successful for me.

Readers may use this article Installing Mac OS-X El Capitan 10.11.1 in a 2006 MacPro 1,1 for general reference of my method. Beware that the MacPro 1,1 needs a compatible graphics card. The one that I used is GeForce 8800 GT/S. I now have a MacPro 1,1 running OS X El Capitan. Special thanks to Pike who undertook the work creating his boot.efi. Gratitude is also towards Pike sharing this piece of work with us.
