1lum3 Posted November 25, 2014 Share Posted November 25, 2014 I had my Mac Pro 1,1 running 10.10 and on the system attempted an update install to (I believe 10.10.2). When it rebooted I got the blinking ? folder. So to diagnose I booted back into 10.7.5 and discovered the boot.efi had been created and modified in the update in both /System/Library/CoreServices/ and in /usr/standalone/i386/. I tired copying over Tiamo's boot.efi again (and repairing permissions etc.) but receive what looks like a kernel panic on boot. Any Thoughts would be appreciated. I really need the system back.

aww Posted November 29, 2014 Share Posted November 29, 2014 Your HW may be too old. minimum: Graphiccard must be QE/CI able i have success with these old cards: Nvidia 8600GTS and ATI 5450 also memory may need 2G+ Try: Chameleon or Clover loader (try different versions) Newer version may not be the best option.

jamiethemorris Posted November 30, 2014 Share Posted November 30, 2014 Post the KP message. Pike may need to update it for the latest version of Yosemite or something. As an alternative for now, Clover will work but it takes more configuration. Basically you just set everything to be identical to your hardware.
