    • Upgrade Sierra 10.12.6 - GT 710 Hi!! I have make a upgrade 10.12.6 Sierra and have a black Screen. Solution: Change SMBios for IMAC Retina. I hve a Core I7 3770 Ivy bridge.   
    • It did not work for me. In my case, I found that the installed Volume was renamed to "--" and the installation script stopped. After that the Volume was damaged and I had to erase it with Disk Utility.   I suspect that the error does not come from the script itself but happened prior to run the script. Some process was messing with the installed Volume.  
    • How Do I Get iCloud Working in Yosemite Zone? Hello! I recently installed Yosemite Zone and iCloud, FaceTime, iMessage, and Google Chrome and none of them work, each saying my computer isn't validated. I have tried many things including the one with EFI Studio and deleting stuff to messing around in Chameleon and none of it seems to work. The App Store and it's sister apps work just fine, though. Does anyone know how to get all this working, as they are things I'd like to use. Specs: AMD Phenom II x4 B55 3.3 GHz 8 GB DDR3 NVidia GeForce GTX 750 MSI 890GXM-G65 Yosemite Zone 10.10.1
