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