Mountain Lion using myhack tool, runs perfect in my another Pc... fast, stable, clean myHack | Taking the iFail out of iHack In the notebook y have this problems: Normal boot with USB myhack: pci configuration begin. Patching the USB with your kexts solves the problem, but appears: waiting for root device. This same issue i will have in my another Pc, and solved making a 8 GB partition in my HDD, and using again myhack tool to create there another boot installation like the USB. When MyHack finish, rename this partition adding HDD to the finish, for not confusing with USB partition who have the same name. Now boot Pc with USB stick, and select the HDD partition to start installation. All by defect (MyHack ask you a few times during installation) and reboot. You must boot from USB, until you update your chameleon versión in your normal boot partition with MyHack tool too. In the notebook with Lion, i was not able to create this partition with MyHack, due the program does not recognize root partition ¿?, and the option to create 10.8 installation does not appear. In my Pc, i create a image of this partition with partition tool, save it in another USB and restore it to the notebook. Booting notebook with the USB, i have again waiting for root device. Updating chameleon with MyHack in the notebook for not need to use USB for booting, i have the same issue. (waiting for root device) Can you probe it?
