    has anyone made a hackingtosh with one of the new motherboards that have efi rather then bios on them?

    i'm looking to make one out of my powermac g5 but i'm unsure what motherboard to get, i mean it the efi boards work i imagine they will work a lot better.

    didnt know where to post this, sorry

    I haven't heard of it being done. In any case, the EFI firmware is not the same in a PC motherboard.

    The CPUs aren't available yet so it's impossible to say. Your best bet is to follow Hackintosh forums such as InsanelyMac and TonyMacx86, here is one SB thread

    I used to have an EFI motherboard I ran OS X on. Still not compatible. Sorry. You'd still need to hack it.

    Apple wasn't that stupid. OS X is still locked to Apple specific EFI boards.

    what do you mean the cpus aren't available yet?

    Intel only gave permission to release reviews, the CPUs won't be out until Friday.

    It doesn't matter whether you use EFI or BIOS. It has no impact on loading Mac OS X. You still have to use the same hacks.

    Likely putting on OS X will kick the board into BIOS emulation anyway.

    So it really doesn't matter. Either way, you'll be running BIOS. Either inside EFI or alone.

    It's not really that big of a deal anyway. EFI on the Windows side looks exactly the same as BIOS anyway.

    agreed, but overclocking is really easy inside efi.

    As long as you buy an unlocked CPU (2xxxK). Otherwise your OCing will be limited to ~5%

    Not particularly easier than BIOS, actually... Overclocking on my EFI board was the same as overclocking on a BIOS board.

    Sandy Bridge hardware will be around the same price current processors and motherboards are, so you'd be better off waiting.

    I like the sound of that, also means I'll have more cash at the time.
    But I will have to wait until a Mac with sandy bridge is launched for the updated kernel right?

    So what hardware would you guys recommend?

    EFI has been on boards since the Pentium 4. It just depends on which board you buy. It's been on PC's for a long time.

    But again, it makes no difference for overclocking. If you are buying a Windows machine, it makes no difference if you use BIOS or EFI.

    If anything, my PC overclocked WORSE when I switched to an EFI board.

    i wouldnt try it until Apple releases Sandy Bridge processors in their Macs and so the vanilla kernel supports them. right now people have hacks working on Sandy Bridge, but they are using hacked kernels, so it isnt fully compatible.

    Indeed. Hopefully Apple releases SNB-based machines soon.

    I'm pretty sure MBPs will be updated between February and March, the CPUs will be available by then and it would follow Apple's normal update cycle.

    OP, beware the mobo price hike

    and what do you think the appropriate action would be? - i'm sure other mobo manufactures are going to increase prices too, if nothing else to gain extra profit.

    Well, if you want to save some money, get the mobo ASAP. On the other hand, 10% increase is most like 5-15$ on average mobo so not that huge deal but if you're getting high-end stuff, then 10-20% increase starts to hurt. I'm just warning, nothing more.

    Just finished building one myself with the following:
    Gigabyte GA-X58A-UD5
    i7 970
    EVGA GTX 460
    6GB Dominator 1600 RAM

    Boots without a problem & after a few tweaks it is stable.

    Nice machine Gman. I've got the EX58-UD5 - one of the best boards for using on a hackintosh, and it's great. I'm running with an i7-930, ATI 4890, and 6 GB of Patriot RAM.

    mulo: just the processor and motherboard would have cost him over $1,000. ;)
