USB 3.0 on 17″ MacBook Pro under El Capitan

I had added USB 3.0 functionality (via a GMYLE BC628) to my Late 2011 17″ MBP as per my earlier post. Mac OS X 10.11 El Capitan introduced a new layer of security that prevented my previous configuration from working.

Fortunately, others have figured out a road back.

Here are the steps:

  1. Backup everything and assume you’re about to trash your system. I am not responsible for what happens here.
  2. Boot in to your recovery partition, or on to a USB installer
  3. Execute:sudo csrutil disable kext. This disables kext signing. Boot back to your native system. (Note USB-booted environments probably don’t need the sudo component.)
  4. Download GenericUSBXHCI.kext to your Desktop
  5. Run KextBeast, install to /Library/Extensions
  6. Reboot
  7. Profit!

Here’s a visual of my final result:



So come along with me on my tale of computery enhancement.
