2006/2007 Mac Pro (1,1/2,1) and OS X Yosemite
Tobyg's script works fine but follow the instructions in post 1584 (I think that's the right post).
The locking and unlocking steps have always been in the guide as it is the only way to replace the Core Services boot.efi (unless you are logged in as a root user. I added some steps about the quotes which might have changed the numbering of the steps.
First of thanks to Hennessie for the upgrade instructions. I'm not a IT person by any stretch of the imagination, but nonetheless I found them to be quite understandable and easy to follow. I am hoping for some help with a relatively minor but annoying problem:
Before upgrading I bought a Radeon 5770 video card that was supposed to be flashed for Mac. However, I get no apple logo when booting after upgrading to Yosemite. Perhaps associated with this when holding down the option (alt) key while booting I cannot see the screen listing the boot options. I got around this by trial and error, pressing the right arrow on successive reboot attempts until the machine booted from the thumb drive. All went smoothly after that. Is my video card not actually flashed for Mac as advertised or could something have gone wrong with the install?
Just to be sure:
After upgrading I noticed the addition of 2 steps, 14 & 15, to Hennessie's instructions under Creating the Yosemite thumb driver installer. These steps unlock and lock boot.efi. I'm assuming these weren't needed in my case since the upgrade worked. If that's a wrong assumption, please let me know.
Finally:
I would like to install tobyg's script make sure the correct boot.efi file is there for future upgrades. Will the fact that the boot.efi in the CoreServices directory is locked be a problem, and if so what's a safe work around?
Thanks!
