Kernel Panic on OS X Update

I recently read of someone’s attempt to update a ProBook 4530s from Mavericks 10.9.3 to 10.9.4. They wrote that the install went smoothly, but, on reboot, they got a kernel panic. Mixed in with the textsplosion that filled the screen was a reference to “AppleIntelCPUPowerManagement.” It looked something like this:

KernalPanic AppleIntelCPUPowerManagement

This screen could not be bypassed by booting into the installed OS from the person’s USB drive. They could only run the OS X installer and use a fix from Terminal. The person ended up finding this fix on the blog of Sanga Collins.

  1. Enter your boot menu via the BIOS.
  2. Start the OS X installer (using a DVD or USB drive) and then open Terminal.
  3. Select your language.
  4. Click “Continue” at the welcome message.
  5. Click “Agree” when asked.
  6. At the “Select Destination” screen, go to the Utilities menu and select Terminal.
  7. When the terminal window opens type:
    • cd /Volumes/[HardDisk–Or whatever your install is called.]/System/Library/Extensions
    • rm -rf AppleIntelCPUPowerManagement.kext
  8. Quit Terminal.
  9. Quit the installer and reboot.
