Make Time Machine Work

For non Broadcom Wifi Card users: This might break your wireless drivers.

First try if your Time Machine works without this hack!!!


  • Download the IONetworkingFamily kext found here (see this thread)
  • Make a copy the existing of /System/Library/Extensions/IONetworkingFamily.kext
  • Install it with kextHelper
  • Reboot
  • Configure your Time Machine settings

In case you get a "The backup volume could not be found" error, do the following (found here):

  • Open System Preferences.
  • Choose Time Machine
  • Click "Choose Backup Diskā€¦".
  • Select your backup location again


If this breaks your wifi, just reinstall the copy of IONetworkingFamily that you have made earlier (or from /Backup Extensions if not).
