MSI GTX 570 TF III PE issue on 10.7.2

Hello to all.

i`m la long time reader of this forum but now decided to post my problem because i can`t fix it myself. And i`m not a computer newbie... So :

My system : core i5 2500k

gigabyte p67 ds3 b3 bios f3

videocard above

8 gb ram corsair dd3 1600 mhz


I installed iatkos l2 without any issues, on an existing partition where i had 10.7.1 running fine with another video card ( gtx 260 OC ). System is correctly set to dual boot win7 and lion.

I upgraded my system so i decided to upgrade to latest lion too, since old installation wasn`t working at all with new card. I use my system only for xcode development / graphic design.

No matter what i did, my card is not recognized, and my system always stay in 1024x768 resolution.

I have 2 monitors, both full hd, connected to dvi port ( using hdmi adaptor ) and mini hdmi port.

What i tried :

adding card id ( 1086, gf110 platform ) in nv100hal kext, system will show black screen after loading

installing nvidia gtx 5xx enabler from osx86 forum, card recognized by name, vram, etc, but still can`t change resolution, also system really slow.

installing/removing kexts for fermi based boards, from osx86, tonymac, this forum, no change...


If anyone have this video card working, please let me know what you did, i`ll be forever greatful.

Thank you very much,

hi there,


I had similar problem as you. Simple adding a card ID or install kexts did not work for me. I was stuck on 1024x768 for 2 days till i figured it out.


Here is what i did


Pure 10.7 (11A511) install using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]. http://www.tonymacx8...Beast-1.0.0.zip (10.7.2 11C74 did not work for my vga)

[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] 4.1 http://www.tonymacx8...Beast-4.1.0.zip (no vga drivers selected, just select PCI Configuration Fix, PCI Root ID Fix, Graphics Enabler and other stuff for your mobo like ethernet, audio etc.)

Using GFXutils http://rapidshare.co...fxutil.zip.html first get your PCI position "gfxutils -f display", then fill out the default nvidia.list with this PCI position, vga name, Vram size, outputs etc (use this article http://forum.netkas.org/index.php?topic=222.0) and using gfxutils make a hex file nvidia.hex from the nvidia.list (gfxutils -i xml -o hex nvidia.list nvidia.hex)

Open the hex file in text editor, copy the content, open /Extra/org.chameleon.boot.plist and add <key>device-properties</key><string>Your Hex content</string>

Next download and install GTX5XX Enabler http://www.osx86.net...xx_enabler.html from kexts site. Install only the driver (the top option) nothing else. ATY_init made my mac keep rebooting on boot.

Repair permissions using Kext utility. http://www.osx86.net...xt_utility.html

Reboot and cross your fingers :)


If it will work, then use this http://www.osx86.net/view/1738-applegraphicspowermanagement_gtx_580,570_10.7.2.html to unleash the full power of your gtx570.


Hope it will help

That sounded advanced! But, will it also enable GTX5XX fan control from OSX? I am worried about the temperature on my card and have to boot in W7 now and then just to cool it down.


Does anyone know more about the fermi cards and if it is possible to control the fan speed within Mac OSX?
