This problem started happening right after running EasyBeast. I didn't install ANY other kexts or make any other modifications. It won't boot all the way up, but if I type -v at the Chameleon screen, I get to see this: kxld[com.apple.driver.AppleRTC]: The Mach-0 file is malformed: Invalid magic number: 0xbebafeca Can't load kext com.apple.driver.AppleRTC - link failed. Failed to load executable for kext com.apple.driver.AppleRTC (error 0xdc008016) I've already tried copying the vanilla AppleRTC.kext file from the installation USB over to the hard drive, thinking maybe the installed version got corrupted somehow. That didn't help. Is there something else that needs to be done after copying the vanilla kext into the system to make it re-scan for changed kexts? I'm running an ASUS P8P67-M Pro board with the hacked BIOS that keeps it from having a KP during the initial install.
