I'm trying to take a cloned installation of 10.8.5 from a Macbook Pro Unibody 2008 to a Mac Pro 1,1. Mac Pro 1,1 Details: Currently running OSX 10.6.8 on an SSD Firmware upgraded to 2,1 Boot ROM Version: MP21.007F.B06 SMC Version (system): 1.7f10 CPU upgraded to 2 x Quad-Core Xeon 12 GB RAM Stock Nvidia 7300 GT Also have a Gigabyte GT730 2GB to try use once Mountain Lion is up and running. Process thus far: 1. Used Carbon Copy Cloner to clone the 10.8.5 installation onto a Crucial 240GB SSD. Selected the option to also create a recovery volume on the drive. 2. Replaced Boot.efi with Tiamo's verbose version at System/Library/CoreServices/boot.efi and usr/standalone/i386/boot.efi 3. Added both 1,1 and 2,1 Board ID's and model names to System/Library/CoreServices/PlatformSupport.plist 4. Placed SSD into Mac Pro. It is the only drive in the system. 7300 GT is only graphics card in system. 5. Reset PRAM on bootup 6. Get a boot loop after some verbose messages, both with normal boot and safe boot mode. I can't get into recovery mode using Command-R or Command-Option-R. It just goes through with normal verbose boot and then loops again. Can someone help identify the problem by looking over the attached startup messages please?
