Mobility HD2400XT (94c8) working with OSX 10.6.3 on a Gateway M6824.
Took awhile, but here’s what worked for me:
1. Retail OSX Snow Leopard 10.6.3 restored to an 8GB usb key with disk utility.
2. Add nawcom modded MyHack Installer (http://blog.nawcom.com/?p=242) with the pkg installer, being sure to select your USB drive. Only options that should be deselected are Chocolate Kernel and Graphics Disabler.
3. Boot with USB key and install normally. You should be able to install to a MBR formatted drive (for windows/linux dual booting).
4. Install fails during post-install phase (after reboot, before registration, etc). Boot in single-user mode (hit tab a few times at the screen, pick the drive you installed to, and type “-s” then enter). mount -uw / as instructed, then cd to /System/Library/Extensions and rm -rf ATI* (all ATI files). reboot.
5. Boot of your new install should now succeed. Proceed through the regular post-installation. Install the boot loader to the install drive using the myHack pkg from the USB drive, using the same options you did before. Reboot.
6. sudo vim /Extra/com.apple.boot.plist, remove both the “GraphicsMode” and “GraphicsEnabler” entries (both the key name and values).
7. Download the latest RadeonHD driver (http://code.google.com/p/osx86-driver-radeonhd/downloads/list). Download KextUtility (http://www.google.com/search?q=kextutility). Install the RadeonHD kext by dragging it onto the KextUtility icon.
8. Reboot normally. You should now be at 1280x800. If you have an ‘color-block’ mouse cursor (I did), modify the /System/Library/Extensions/RadeonHD.kext/Contents/Info.plist and set the key “enableHWCursor” to false. Reboot.
Haven’t got QE/CI working yet, but not sure how much I care. The built-in wireless is not really supported either, but I purchased an Airlink Wireless-N usb dongle that is fairly small in size and has native OSX support for under $15.
Still seem to have a few overheating problems, but have been running the machine without a shutdown on a cool-pad for the last few hours, so it seems possible to mitigate these issues.
Hope this helps someone! I’ve been trying to get this working for over 2 years now.
