At first, sorry for my bad english!
I installed Mavericks downloaded from the app store
It all works great, my only problem is that 4 minutes after my pc goes in stop mode, it reboots automatically, ONLY IN STOP MODE
OSX boots great -----> after some time it goes in STOP ------> after 4 minutes it automatically reboots ...
the only kext that i installed were:
-ElliotForceLegacyRTC : delete this kext
-NullCPUPowermanagement use a pached AICPM and delete this kext
-appleacpiplatform rollback 10,8,1
-AppleRTC Patch for CMOS Reset, use the original kext from 10.9, if have problem with Bios CMS Reset, patch the kext
