You need to patch the AppleRTC.kext. Open your Terminal and follow these easy steps:
1. First backup the original kext:
mkdir ~/Desktop/BackupRTC
sudo cp -r /System/Library/Extensions/AppleRTC.kext ~/Desktop/BackupRTC/
2. Copy the original kext to your desktop for patching:
sudo cp -r /System/Library/Extensions/AppleRTC.kext ~/Desktop/
3. Patch it:
sudo perl -pi -e 's|\x75\x30\x89\xd8|\xeb\x30\x89\xd8|' ~/Desktop/AppleRTC.kext/Contents/MacOS/AppleRTC
4. Delete the original version:
sudo rm -rf /System/Library/Extensions/AppleRTC.kext
5. Copy the patched version in the place using Kext Wizard, rebuild the permissions and the system cache.
6. Reboot.
