  1. Hmm. I forgot to mention that I'm running a vanilla install. I'm used EmpireEFI to install, then replaced it with MyHack after installation. I used a GUID disk, but after that moved the OS X partition to a MBR disk via Linux (mv -p). Not too sure if these matter though. We have the exact same graphics card.
  2. For Snow Leopard: Note that kextcache -k is no longer supported. At least on my system, it shows: yjwong-macbookpro:~ yjwong$ kextcache -k -k is no longer used; ignoring. No work to do; check options and try again. Instead, do a: sudo touch /System/Library/Extensions And the system will regenerate the kextcache upon next bootup.
  3. My bad. I accidentally left out the RadeonHD.kext. Have you tried loading the kext manually? cd /System/Library/Extensions sudo kextload -v 6 RadeonHD.kext
  4. Hi Fuzzy_Logic, You can use plist editor to change the EDID (from Xcode Tools), it's safer since plist editor does the Base64 encoding for you. Anyway, I have changed it for you and attached in this post. Are the permissions for your RadeonHD.kext correct? You can check whether RadeonHD.kext is really loaded by going to System Profiler -> Extensions. Check if RadeonHD.kext is in the list. If it's not there, make sure RadeonHD.kext is owned by root, group wheel. Directories have permissions 0755 and files 0644. cd /System/Library/Extensions sudo chown -Rvf root:wheel RadeonHD.kext sudo chmod -Rvf 0775 RadeonHD.kext sudo chmod 0644 Contents/Info.plist sudo chmod 0644 Contents/MacOS/RadeonHD sudo chmod 0644 Contents/Resources/English.lproj/InfoPlist.strings You're supposed to remove ATIRadeonX2000.kext by the way. Regards, yjwong VAIO_plist.plist.zip
  5. I got my ATI Mobilty Radeon 4650 (1 GB GDDR3 VRAM) working with native resolution. No QE/CI though. Running under Snow Leopard, using an Asus n81Vp notebook. 1. Remove ATIRadeonX2000.kext (using something like another OSX installation or Linux). 2. Install RadeonHD.kext from start of this topic & repair permissions. Reboot. 3. (Got screen with screwed colors on reboot (but was in native resolution already) 4. Used plist editor to edit EDID to your own display's EDID in Info.plist of RadeonHD.kext 5. Install edited RadeonHD.kext 6. Repair permissions. 7. Enjoy native resolution! =D If you get black screen, try to attach external monitor via VGA.
  6. Mobility radeon 4670

    I'm using an ATI Mobility Radeon 4650 instead (both have same dies). But I've been able to get native resolution (1366x768) on the internal display panel via dong's Radeon HD framebuffer project. No QE/CI at the moment. Needed to remove ATIRadeonX2000.kext elsewhere for RadeonHD.kext to work.
