I have been driven mad by the recent changes in iMessage registration which have resulted in the dreaded 'Contact Apple Support' error. For those with an Asus Series 6 or 7 Chipset mobo (sandy / ivy bridge) then here is the fix that finally worked for me: Go here to download the excellent FD44Editor and FTKToolkit (all credit to the developer CodeRush for this great piece of software): http://hardforum.com...d.php?t=1726429 Please read this page carefully before you proceed so you understand what you are doing. The usual warnings about flashing your bios apply here as always. Use the dos toolkit to dump a backup of your bios as per instructions on the webpage. Keep a copy of this safe just in case... Use the FD44Editor to change your System UUID and MAC address of your Intel GbE onboard ethernet Flash the fixed bios back using instructions on the webpage Clear CMOS and restore your original bios settings Use your bootloader of choice (Revoboot/Clover) to provide necessar...

This quick dsdt edit seems to work. You can inject this via efi device properties too. Insert the device code wherever you have USB3 in your DSDT (find this using ioreg), naming each device XHC1, XHC2 etc... Device (XHC1) { Name (_ADR, Zero) Alias (PW94, _PRW) Method (_DSM, 4, NotSerialized) { Store (Package (0x0A) { "device-id", Buffer (0x04) { 0x31, 0x1e, 0x00, 0x00 }, "vendor-id", Buffer (0x04) { 0x86, 0x80, 0x00, 0x00 }, "name", Buffer (0x0D) { "pci8086,1e31" }, "subsystem-id", Buffer (0x04) { 0x70, 0x72, 0x00, 0x00 }, "subsystem-vendor-id", Buffer (0x04) { 0x86, 0x80, 0x00, 0x00 } }, Local0) DTGP (Arg2, RefOf (Local0)) Return (Local0) } }  usb3.tiff 59.73K 244 downloads...

sea_man, on , said:In my bios ( Asus rampage IV gene ) X79 there is not module called "PowerManagement" ... :( Seems like i will wait for another solution to have Speed step . Anyway thanks for the tutorial ! Buoo is correct, you use the old method but speedstepping will not work and AICPUPM.kext will kp on boot. Our only hope there is that Apple decide to use Sandy Bridge-E Xeon CPU's in an updated version of the MacPro, which is anybody's guess :worried_anim:

First of all I'd like to say credit where credit's due. This has been a joint work, the crucial link being provided by Revogirl. Read and learn how it's done so you can unlock your own bios, google to find the tools you need. Remember that this tutorial is using my bios as an example. The byte strings in yours may be different. This is a risky procedure, do not attempt unless you are confident with modifying and flashing your bios. A mistake could easily brick your board Use Phoenixtool in a Windows VM to dump all the EFI modules in your bios (a folder called DUMP will appear on the desktop when Phoenix tool runs). Then look at your bios in Aptio MMtool to get the GUID of the powermanagement EFI module. Now look through your DUMP directory until you find the ROM module with the same GUID. In my bios it's called 8C783970-F02A-4A4D-AF09-8797A51EEC8D_1_393.ROM. There will be two files with the same GUID, choose the larger one. This is your powermanagement modul...

I've had a number of PM's about this so here goes. This board makes for a great hack, mine is currently running Lion with a geekbench score of 15500, solid as a rock. First of all I'd like to acknowledge/credit DHP, blackosx, flAked and THe KiNG without whose hard work this wouldn't have been possible. Make sure you have the attached bios installed. This is hacked to allow CPU Power Management to work. REMEMBER: IF YOU'RE NOT FAMILIAR WITH FLASHING A BIOS THEN DON'T DO IT. I cannot stress this enough, making a mistake could trash your board Bios Settings: Extreme Tweaker AI Overclock Tuner = Manual Turbo ratio = By number of active cores mode For i7 2600K (you'll need to get the correct settings for your CPU): 1-Core Ratio Limit = 38 2-Core Ratio Limit = 37 3-Core Ratio Limit = 36 4-Core Ratio Limit = 35 Internal PLL Overvoltage = Disabled Advanced\CPU Configuration CPU Ratio = Auto CPU C1E=Enabled C3 Report=Enabled C6 Report=Enabled Package...
