Here is the kext I made for 10.7.5, ATI6000Controller.kext.zip . I really don't have the time, and honestly, if you bothered to type two words in Google (installing kext) you will get what you need. So I wont help you here.

[FilipBielik]

I can install kext. I try it.

 

I install it, boot, but still resolution 1024x768 What to do. I m using 3mb spdisplays_display

(10.7.5 64bit)

 

EDIT: In Champlist I changed AtiConfig to Impomea (or what ) and changed resolution to 1600x900, now its resolution OK but I dont have display driver.

[Trucker MK]

IT work in OSX 10.8.2

Acer 7750G , Ati 6650m 2GB

[Trucker MK]

Yeah, 16 downloads, 1 reply after 10 days, I already know that. Thanks.

By the way, anyone have to share some kexts (experiance) for 10.8.x, I am a little outdated. I have my Lappy up and running again, huge thanks to nai22.

[Jason102]

Since you are apparently a magician, will you do the the ATI6000Controller.kext for 10.8.2 for the 6450M?

[Trucker MK]

Did it worked in previous versions of OS X?

 

I found this Pithecia modified Framebuffer personality for 6450M

 

00 08 00 00 04 03 00 00 00 00 00 00 21 03 03 02

04 00 00 00 14 02 00 00 00 00 00 00 00 00 04 04

10 00 00 00 10 00 00 00 00 00 00 00 01 00 00 01

 

If this is correct, i can make it.

 

Edit.

Have you tried this? http://www.osx86.net/view/3125-xfx-sapphire_ati_radeon_hd6450_full_qe-c_...html

[Jason102]

I haven't tried that link (somehow after all of my searching I missed it). I did do several things today to try and get it working. I dumped my video bios, used the radeon_bios_decoder and redsock decoder to modify the ATI6000.kext framebuffer personality (I used Hydrilla). I also tried to add my video card to Chimera's ati.c but apparently it doesn't compile with xcode 4.5. No real luck with anything.

 

I'll try that link and personality, maybe they'll do the trick. One question: does the framebuffer "personality" that you modify really matter as long as the numbers for the output profiles are the same? If I have 2 personalities that have 3 outputs each and I set them to the same 3 16-byte values, are they then the same? Or do they affect something else along the line?

I have come to a conclusion that the not working LVDS is caused by my EDID not being right. All the guides tell me to edit the DisplayProductID-717.

Currently I am running Pithecia with 00 08 00 00 04 03 00 00 00 00 00 00 21 03 03 07 for the LVDS, by using Pithecia I achieve getting 2 screens to show under the monitors settings.

But the problem is that both of those monitors use the same EDID, and are classified as the same monitor, so changing resolution on them both have an effect on the VGA.I would like to continue using the VGA screen, so I dont want to give up on it, but Id like to get the LVDS working also.

 

How big is the chance that a not working LVDS is caused by an invalid EDID? (It is completely black, no backlight, the backlight has never worked with all the hundreds of combos I have tried)

[Trucker MK]

You are using Connector Type 0x00000800, which is for HDMI, why
