OK, so I managed to get Mavericks installed via the "Old School" Route - Burning an iBoot-Haswell CD then installing 10.6.3 then upgrading that to 10.6.8 which allowed me to create a Unibeast boot USB flash disk with 10.9.3 after downloading it free from the App store. Believe it or not, THAT WAS ALL THE EASY PART!
Took me about 4-5 hours with all the trial & error. I installed 10.9.3 with no problem from the bootable Unibeast USB flash disk. Then came the hard part. I rebooted into the install & used MultiBeast 6.3 to install FakeSMC, an iMac 14.2 SMBIOS, etc. - all the typical bare essentials needed to boot a Hack.
Upon reboot (& everytime thereafter) I keep getting stuck at this damn message:
"DRMStatus: iTunes/Apple Store Content Access Problem. Content playback may be disabled on this computer. You can Continue to use the machine, but you should contact an Apple support representative. ErrorCode: 8877652"
Right before that, I'm also seeing some messages about Bluetooth, where it sits for about a minute, then goes on to the DRMStatus message. I've tried everything I know of between BIOS settings (optimized defaults included) different switches at boot, and different kexts and nothing seems to work. I've even tried using the built-in video in my i5-4670K and a Radeon HD5450 Vid card, with USB Bluetooth transmitter that has built-in support in OS X, and with/without my Broadcom-based PCI-E Wireless 802.11N card. Makes no difference.
The only way I can get into the system is with -x boot flag.
I've built quite a few Gigabyte-based Hacks, & this has easily been the most problematic. Maybe it's the new Z97 chipset? Anyone have any suggestions?
Please save me from having to use Win 8.1 or Linux on my new PC.
Thanks!
PS: As a last shot, I'm going to try to install the latest version of Clover boot loader but I'm not holding out much hope.
