I run an intel-powered multiboot system (one HDD is Mavericks 10.9.2, the other one is Windows 7). HDD with OSX was the primary one to boot, all was fine for half a year, but today I was rebooting from Win to OSX and somewhy it was Win booting again (despite OSX HDD priority).
I rebooted again and got the "The data in EC or EC flash might be corrupted" error.
Extracted the battery of the motherboard for 5 minutes, the error's gone, but OSX just won't start - stuck on flashing "_".
If I disconnect the Win HDD, the system gives me "Reboot and Select proper Boot device or Instert Boot Media..." etc.
Windows boots just fine for some reason.
What could be the problem and how to fix it?
Main components of the system:
intel i5-2500 3.30ghz
Asus P8Z68-V LX
AMD Radeon HD 6800
Don't know how to delete the topic and if I need to at all. Maybe it would be useful to someone, maybe not.
- created a bootable usb-stick using Mavericks ##### (yeah yeah those guys) from my another mac - booted up from the stick choosing to boot from my HDD which contained installed OS X - found a problem with "Missing Bluetooth Controller Transport!" - booted up in safe mode with -x, added dart=0 to the chameleon's kext in /Extra
This fixed the problem. I guess, something went wrong after resetting the BIOS (VT-X appears disabled there).
Solution was inspired by themacmeister from reddit
i managed to install os x el capitan yesterday and since then almost everything worked except the AppleRTC patch so i get a cmos reset every time i sleep or wake the device .
back on Mountain lion , Maverick and Yosemite i used this patch
sudo perl -pi -e 's|\x75\x2e\x0f\xb6|\xeb\x2e\x0f\xb6|' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC
sudo touch /System/Library/Extensions
the patch isn't working anymore , anyone patched it yet ?
I am happy with my hackintosh since two years. I just recently upgraded to OSX Yosemite, starting with 10.10.3.
I did a complete reinstall on a new SSD and I have the problem that I have random CMOS setting resets since than.
It occurs about once a day and it never happened before.
In Clover.config, there is
which should prevent the reset with patching of AppleRTC.
Any help is appreciated.
