RadeonHD 4850 and Leopard, finaly!

using 10.5.7 beta ati drivers (jsut five kexts) and new natit, i got my 4850 working in 10.5.6 Leopard :)

You need to have OSX 10.5.6 or higher

What’s working – qe/ci, resolution change

What Problems:

currently only second dvi port works for me, and only with dvi-vga adapter

also, Display is recognized as standart vga/svga display, so only 4:3 resolutions available

only usefull for VGA connections –  with switchresx(before using it, make sure u can change resolution) help i added 1680×1050 mode jsut fine :)

EDIT3(for4850): booted with dvi2vga(converter only, no monitor attached to it) in second port, and dvi connected to first port(closest to mobo), and voila,

display on first port properly recognized.

some vertical little screen jerkness sometimes

Pkg with drivers  you will find in #radeonhd room on

and now some screenshots

User with 4870 reported he has almost no problems with 4870, he just cant change resolution, results in black screen

Btw, 10.5.7 kernel also supports Nehalem i7 fully now.

P.S. I hope no other company than Apple/AMD will pretend they wrote drivers for 4850/4870 or nehalem i7

    Wow, that’s great, netkas. Do you know if the ati 4670 will also work with these kexts?

  8. February 26th, 2009 | 8:41 pm

    NO WAY!!!!

    Are there going to be download links anytime soon??

    February 26th, 2009 | 9:49 pm

    I knew when I saw the news for 10.5.7 “graphic updates” that there was hope. I go here and sure enough there it is. Great work!!! Now I can use my 4850 instead of my crappy gma950.

  10. Maik
    February 26th, 2009 | 10:07 pm

    yes, it works fine. I used switchresx to chage resolution, too. thank you so much!

    But I’m not entirely there yet, does it work for 4670 too?

  14. Simon
    February 27th, 2009 | 12:26 am

    i downloaded the drivers and installed it, (didn’t reboot) then used SwitchResX and added custom resolution of 1680×1050 because it still show 1024 x 7xx.. and when i restarted the comp and i try to boot it shows a split second of the os loading but then it doesn’t detect my display anymore, so can’t get into os. HOW CAN I FIX IT…?

  15. netkas
    February 27th, 2009 | 12:27 am

    if u booted and cant change resolution to any other – DONT USE swithcresx

  16. Simon
    February 27th, 2009 | 12:32 am

    well first after I installed the package I didn’t restart and wanted to change the resolution, but it only showed one, 1024×768 so I turned to SwitchResX and made a custom resolution.
    But now I can’t even get into the OS and change it back. Any ideas how to fix this?
    Thanks for the quick reply by the way, much appreciated

    Sorry for write here again.
    Is it possible to make a pcefi “usb version” to work like efi-x as a boot device?
    Could you release a version for this?
    We could have a poor version of efi-x (and sure more compatible) and this could be great.

    Thank you and sorry again for my english.

    Well done.
    I just wanna know one thing. How HD 4850 became supported with these new kexts, i was thinking if with HD 3200 would work too. I was thiking in reinstall OS X 10.5.6 and try to make it work modding these new kexts.

    Thank you.

  29. MacLover
    February 27th, 2009 | 6:37 pm

    Installed on 10.5.5 (Intel) with HD4870, no problem at all so far!
    It works! No errors, no jerkness, full QE/CI support.
    Used 1st DVI-Port with dvi-vga adapter, resolution 1600×1200.

    Thank you very much :-)

    February 27th, 2009 | 9:30 pm

    TRied on 10.5.6 with a 4870 512mb (Displayport, 2 dvi and hdmi) but neither of the dvi work… i mean i see the grey loading screen at os X boot but then the screen gets black. Any idea?

    February 28th, 2009 | 12:25 am

    just out of curiosity have you been able to hack into the EFI-X device to see if they are using other peoples work and passing it on as there own??

    Great Work by the way keep up the good work

  33. February 28th, 2009 | 12:39 am

    It work on a sapphire HD4670??

  34. rj

    February 28th, 2009 | 7:54 am

    Hi netkas !
    Can you try to do that OpenGLViewerBench with setting Musltisampling *4 ?
    I get at 1600×1200 with ATI 3850 not much less (about 15% less) – FSAA*4 will show more difference because GPU+VRAM Speed is much more relevant.

    Also i have an really good shader-bench, its an sceensaver (UB) that computes game of live algorithm on the gpu by shader coding. Shader speed of 48XX should be much better than older ATI 2XXX, ATI3XXX.

    You can download the GPU_Life_Saver “Bench” here:
    Set the GPU Lide Saver Options : deaktivate FPS Limit, zoom=1, let it run in fullscreen.
    I get around 500 FPS, 1600×1200, ATI 3850 GDDR3. My ATI 2600XT friends much less, also NV 8XXX much less, because less shaders. Intel GMA works but ist like slide show – CPU must compute all 😉
    The Test is really CPU independend, doesnt matter if lowend C2D or Quad so much for the fps results.

    February 28th, 2009 | 3:22 pm

    HD 4850

    1 install
    2 reboot
    3 monitor was black so moved cable (vga + dvi2vga adapter) to other dvi (furthest from mobo)
    4 reboot
    5 works as advertized!!!

    I don’t have wide screen so didn’t need switchresx
    getting the screen jerks also but happy for now

    this solved my need for quartz extreme – vmware fusion virtual machines would not run without it

    netkas u da man!!!

  41. March 1st, 2009 | 12:57 am


    After trying many bioses I found the problem is on the clock settings, the memory must be the same speed in all settings, I found this using RBE and looking at the sapphire BIOS and the 4870 stock, so I put the same speed (993 MHz for memory clock) and it works!, this fix the kernel panic with the sapphire bios, and fixes sleep and resolution change. You still need to use the DVIVGA adapter.

    EDITed by netkas: Thank you very much for finding, but it’s dangerous a bit to flash bios, i have found software solution, so , dont flash your bioses guys /EDITends

    Be careful when flashing your card, I’m not responsible for any damage to your card.

    Hi, I have a visiontek radeon 4870 with DVI, HDMI, and VGA ports. No luck on getting it to work, either blank screen after loadup or lightblue screen depending on what I have connected.

    Yes… My dual DVI output is working…

    I had read all the comments about DVI output not working in 4850 (only with DVI-VGA adapter), but I rebooted the machine after package installation without removing the DVI cables to give me a try… And it works! =D

    Can you send me an email message at my email??? (the which one I used here) I’ll reply your message with ioreg dump.

    Thanks again by the package…

    Awesome! thanks for the kext.

    I can confirm that it works with a Visiontek HD4850
    with Kalyway 10.5.2 ( After some tweaks, had to remove several ATI kext after booting -x) and it runs with QE/CI 4:3 max res

    now I can finally run virtual machines : )

    hey…after posting here the other day and finding out that the 4830 didnt work yet…i decided to go pick up a 4850 to try…i got a visiontek.
    downloaded and installed your package and it works great!

    I decided to try connecting both using 2 benq fp93gx monitors..both connected via DVI.
    i reset the computer and booted into osx..and they both work!!!
    all of the modes work, i can move them around..etc.
    I have the desktop extended right now, and im running a screenshare from my laptop and doing a diskcopy (both on the right screen)…main desktop and this safari window on the left screen…no problems yet..runs perfect!
    let me know if you need any info about my setup or a IO dump

    i have screenshots too of the profiler with the display info for both displays..
    let me know if you need anything

    So, any one got some idea’s to get this working? I’ve tried everything I could find on the web.

    I am having problem with DL DVI too. Everything work except that. If I use 30CD as the only screen, I get all rubbish on the screen when login window tries to start. If I use 30CD as secondary display, I either get it working but only have max 1280 X 800 resolution on 30CD or sometimes if the option of 2560 X 1600 appears in System Preferences for 30CD then I get black screen on 30CD.

    Works well with a small problem: After going to sleep mode and starting again, it seems that the card will not be initialized correctly – the picture is broken. Any idea how to solve this issue?

    With this amazing work, have you by chance taken a look at adapting this to suit the ATI Radeon 4830 graphics card.
    I have a fully functional 10.5.6 system in place and would be glad to test out anything you have related to this card.
    Thanks for all your efforts.

    also netkas: can you tell us how you get the videobios info so we can make our own binary codes to add into the natit… maybe this can increase the amount of tests… esp for different 4000 series…

    netkas: ok rbe can extract hex, after that, do we need to alter/modify anything in the settings of voltage/fan/memory/gpu clocks? and what will be those aterations based on? thanx

    Works AWESOME.

    Netkas is simply the greatest.

    Works great with Dual HD4850 volt modded to 780Mhz.
    It’s in CrossfireX, but I don’t need to remove the bridge for 10.5.6 to see two separate cards in Leopard.
    My E8400 is running at 4.2Ghz, but Leopard on sees 3.8Ghz.

    Hi, i had the blue screen flash problem on the dvi ports on my gainward 512mb 4850.
    i solved it by typing in “-f -v” at boot and it changed to native resolution (1440×900) automatically and works fine.

    Is there any word on the ATI 4670 problem yet? I have an actual Mac Pro 1.1 OS X 10.5.7. If I need to go an earlier version of OS X to make this work I can do that or if it looks like there will not a solution I guess I have to go full windows 7 then.

    My system: AMD Phenom 9950 @ 2.6, MSI K9A2 mainboard, ATI Radeon 4850 (also MSI).

    I was running iDeneb 10.5.6 @ 1024×768…downloaded your drivers, installed, them and now have 1280×1024 on reboot without even touching the Linux shell.

    The only little catch is every so often the screen will look like it just shakes a hair, down then back up.

    But I’m really glad I have the res. Thanks a lot for your work in this area!

    ////u dlaoded some old natit prolly, use latest one and no screen shakes then.

    I really don’t get my hd 4850 working in 10.5.7. I’ve already tried everything, any natit.pkg or driver packages. I’ve tried several combinations of kexts, for example natit and ATY_Motmot i found anywhere. I followed several guides but nothing worked for me. Can you help? Maybe I’m out of date but i really searched.

    ////am I looking like telepatic ?
    ///if u use vga display, then there is almost no hope.

    Downloaded from here and installed but nothing happened. Nothing shows in display settings other than 1400×1050 which I already had. Am I missing something here? Was I supposed to do something else with the .pkg file?

    I was having a gray/funky screen when installing all the texts, so I decided to install them one by one. I have a Sapphire ATI Radeon 4830 HD. I’m not entirely sure if the order matters, but here’s the order I did them in anyways.

    1) Natit
    2) ATY_Init
    3) ATINDRV

    And that’s it. Hope this helps!
