Updated version

Over the last few weeks there's been a lot of advances in getting X4500 support in osX86. At the moment only framebuffer works, which means getting native resolution, no QE or CI yet, but hey, it's already great to have native resolution.

Coldequation has modded a patcher script provided by Trauma, with wich you can patch the stock AppleIntelGMAX3100.kext's to give support for X4500 graphics cards.

All you need atm is your device ID (you can find it in system profiler (/Applications/Utilities/System Profiler or about this mac --> more info) under graphics section. The device ID starts with 0x and then 4 numbers, probably 0x2A42 (for X4500MHD)

Once you know your device ID, download the script attached to this post, then follow these steps:
  • Start a terminal
  • type sudo -s and enter your user password
  • drag the script from the location you downloaded it from to the terminal
  • at the end of the line, add following options: -rf *your device ID* (it should look something like /Users/username/Downloads/patchX4500.bash -rf 2A42
  • Press enter. The command will give you some output for feedback.
  • Once you executed the script, repair permissions using disk utility (in Applications/Utilities, click on your primary harddrive, and on the first aid tab click on repair permissions.) This might take a while, but will make sure that your driver can be loaded.
  • Reboot and (hopefully) enjoy native resolution
Make sure you have the vanilla version of the kernel extensions (being AppleIntelGMAX3100.kext and AppleIntelGMAX3100FB.kext in /System/Library/Extensions). This only applies to people previously running kernel extensions provided by me in the other thread.

Please post your results in this thread, be it good results or bad results, we'll try to help you ;) . In your post please include hardware info (both laptop type/brand and video card device ID) and software info (osX version and distro)

If you don't get response here, you can (most of the time) find me or other guys willing to help you on the IRC channel #GMA_X4500 at irc.voodooprojects.org

I'll update this thread every time a (more or less) stable breakthrough has been made, and everytime a new patcher script comes out.
known issues
  • Cursor vanishes
    --> workaround: change the cursor size in system preferences -- mouse (till it's really huge, not so handy, but at least it works :P)
  • vertical stripes
    --> No workaround yet, looking into it atm
Last update: July 15, 2009 at 23:17 CET: New patcher script

I hope you get QE/CI - that will open up a lot of boards for use...

keep up the good work,

It's maybe interesting for everybody who got it working to write down the hardware they use in their post, so other people using the same hardware can find the procedure and if it works or not :)

I've got a Toshiba L300-19F (Model PSLB8E-01200DBT) and it's working (as said before, no qe/ci, but I get native resolution without having to use a complex hack, and can switch resolution.

Hello there,

I've tried the kexts with latitude e6400 but i've faced all the time same problem of blue screen before my desktop comes to alive.

i've tested it with 10.5.6 and 10.5.7 but with no luck.

We really need of some help here from all OSX 86 gurus....

Please listen to the public.

Very interesting..

I was involved with getting the GMA950 driver hack to work a few years ago using the same hack method that you guys are describing. Can I ask what does system profiler report?

Does it report as a X3100 type Graphics card? if so has anyone tried EFI strings to get QE/CI working?

Just a thought??

We tried using a custom DSDT to get the same effect.. System profiler did report X3100 before trauma made me a custom DSDT, now it reports X4500.. But we're stuck, any help of people knowing more is welcome! Look at the originating thread I posted in my first post, at page 11 there is an analysis of what seems possible to do..

If you get a blue screen and nothing else, remove the AppleIntelGMAX3100.kext, we're still looking for a way to be able to use the AppleIngelGMAX3100.kext properly :)

Unfortunately this isn't working for me. I have a new SX2800 system. Specs here:
http://www.gateway.c...1.php?tab=specs

After reboot, I do see the two AppleIntel files mentioned in the right directory but when I go to system preferences -> Displays, it still only shows me the single option of 1024 x 768

I'm new to MACs and any help you can provide would be appreciated

Thanks

Have you used correct device id?
The desktop version is different from mobile version.
Please read post #1 carefully.

Can' get it to work... I'm sure I'm getting the right Device Number, and is the same as yours, and Im sure it's mobile 'cause I'm on a Notebook (Dell inspiron 1545), and still I can't get it to work.

The System Profiler tells me that no kext were loaded to the Graphics... Any ideas?

PS.: I already tried to boot on -x...

[UPDATE]
I booted on -x and done the same thing, now my screen is black and I can't get past the login screen...

[UPDATE 2X]
Got it to 1024x768 by deleting via command Line (-s) the 2A42AppleIntelGMAX3100 | AppleIntelGMAX3100 | AppleIntelGMAX3100FB

This is specifically for GMA X4500, don't think this method works for X3500.. Can't help you straight away (although, if you look for your device ID and follow this tutorial, it might be possible to get it working.. Though I don't know about it.. Otherwise, look in the forums, it's got a search function, we all had to do it.. I know there's a mass of information to go through, but there's no other way..)

I did the whole tutorial:
-terminal...sudo -s...run the bash script with -vrf 2a42 options (my hardware id is 2a42)
-after that i repair the permissions
-then reboot the mashine (Toshiba Satellite L300-19J, the most hardwares works fine, except the graphic card ;) and the wifi (intel 5100 agn), the wifi hasn't 3rd party support)
-after the reboot, I don't have native resolution, so don't wokr the patch correctly

The mashine is Toshiba Satellite L300-19J, I installed iAtkos v7 10.5.7.

P.S.: I'm a beginner in this OSX thing.

I have a Toshiba L350-20G and the patch fails too, for some reason the device ID is not injected into the kext at all, it's just left with >8086<.
When using pre-patched kext's I get the native resolution, but with white horizontal lines every other pixel, making the display hard to read.
I did notice that without the patch System Info shows that I have a Inbuilt Display attached, however when using the patched kext's it shows no display attached.

I've removed OS X for now, needed the extra space, but will install it again later today.

If you want me to provide and further details just ask.

Haven't had the problem with the script. Technically the end result of the script and the pre-patched kexts should be identical. 8086 is actually the Vendor (Intel) so it should stay as this. It is OK that it says it does not have a display attached. Going by others results it does not affect anything (at the moment :().

Interesting though about the lines. I also get them but when you connect to an external display the lines are not there on external display (they stay on the built-in). At the moment I'm trying with tienneke to address the no cursor issue which seems to be only affecting Lenovo users. Anyways hope to find a solution for this too. Its kind of hard to use with no mouse and white lines everywhere :(
