I confess i'm having lots of difficulties to enable my HD 5450 Silent (device 0x68F91002) under Mavericks. The procedures i took for granted until now - editing the ATI5000 and the AMDx3000 kexts, adding Toleda's patch to my DSDT so i have HDMI audio and booting with GraphicsEnabler=No - aren't working for me this time: the stock AMD5000Controler.kext (formerly ATI5000) doesn't appear to have either an Info.plist or a Version.plist (it's not simply invisible, since ShowAllFiles doesn't make them to show up) and adding them by pasting Lion's both files didn't help at all. The result is i don't have either QE/Ci or proper resolution for my 40'' screen (connected via HDMI) or audio when I boot with GraphicsEnabler=No, and with GE=Yes i'd be stuck indefinitely with the spinning boot wheel. I'm yet to perform these troubleshooting steps:
- Boot without my current DSDT (thus using GE=Yes): i don't know if something changed from ML to Mavericks in this regard;
- Boot with PCIRootUID=1, both with and without my current DSDT;
- Copy the plists from ML's kext instead of Lion's and apply all above steps.
If this doesn't take me anywhere, i'll really need help and will report here.
All the best!
