What to do if Hackintosh Reboots Constantly After OSX86 Install.


Installing the OS X on your PC is difficult till first install. Successful OSX86 installation is depends on various combinations like right Distro, BIOS Settings, Hardware, Patch Selection etc. Most common problem for first time installer is my hackintosh reboots after installation finishes. For first time peoples make sure to read and understand the post given below and our OSX86 Basics section. We always recommend to install on a clean hard disk. If you are suffering from endless reboot after leopard hackintosh install, then follow these steps to solve it.


1. Check your BIOS setup and use the following setting if available :

  • Set Core Mutil-Proccessing disable (if all goes well set enabled)
  • Set ACPI 2.0 Support to yes
  • Set ACPI APIC Support to enable
  • Set CPU Internal Thermal Control to Disabled or Auto
  • Set the Max CPUID Value Limit to Disabled
  • Set the “Execute Disable Function” to Enabled
  • XD (eXecution Disabled) Disabled

Set ATA/IDE Mode Settings:

  • Set Configure SATA as: AHCI
  • Set S.M.A.R.T: Enabled

IDE Settings:

  • Set ATA/IDE Mode: Legacy
  • Set Configure SATA as: IDE
  • Set S.M.A.R.T: Disabled


2. Try to Boot using some Darwin Bootloader Switches (or combinations of them):
rd=diskXsY (where X is the number of the leopard drive starting from 0 and Y is the number
of Leopard partition starting from 1 example: rd=disk0s1)
see “Darwin Boot Options” for more details

3. if you are using kalyway 10.5.1 then try “TOHKERNEL” at the darwin boot prompt it will boot TOH kernel instead of the vanilla one (this solution is mostly for when the DVD reboots befor getting to the graphical install screen).

4. Make sure you have at least SSE2 Processor.

5. Reinstall OSX86 with minimum options in customization.
6. Remove hardware parts you don’t need for the install process (like PCI cards, 1.44, USB deices etc.) 

7. Try to install OSX86 on a blank Hard Disk.

    hi guys,

    I installed the latest XXX_x86_10.5.6_Install_Disc_.. and had problems with constant reboot.

    I installed this thing 20 times. the last thing I did was choosing to install the alternative Kernels. that worked.

    If you have a Core i7 board (X58) and using a distro, I found through a bit of searching that you must choose Voodoo kernel, as Vanilla kernel reboots after Starting Darwin/x86.
