GA-Z77X-UD3H - ATI 6950

[gnarfy]

Hi everyone. got some free time this week, so I tested maverick on my computer.

 

specs:

i7 3770k ivy bridge (hd4000)

16Gb DDR3

Intel 335 SSD

ATI 6950 (flashed to 6970)

 

finally I was able to make everything working.

 

process:

 

1st. remove the ATI Video card

2nd. Create a USB Mavericks bootable key (many DIY on this)..

3rd. download FBrotate from Apple Store

4th. on prefs, users, add FBrotate at the startup (it will resolve the blank screen from the 6950/6970 bug)

5th. install latest chameleon, edit org.chameleon.boot.plist

add

        <key>AtiConfig</key>

        <string>Gibba</string>

        <key>Boot Banner</key>

        <string>No</string>

        <key>Graphics Mode</key>

        <string>1920x1080x32</string>

        <key>GraphicsEnabler</key>

 

        <string>Yes</string>

6th. reinstall the video card, boot your favorite OS, you should see the 6950 correctly on the system information (if it's ok, you will see Graphisme  AMD Radeon HD 6950 2048 Mo, if not you should see 6xxx)

 

congrats, you have a working ATI 69xx mavericks setup, no integrated video / switch things to do...

I already changed kext trying few diffrent ones and booting is stright without any problems but unable to watch a movie and launcher is laggy.
