  • Run the following instructions:
  • Disable the Apple SIP Protection as follows:
    • Click the Apple menu.
    • Select Restart…
    • Hold down Command key and R key to boot
    • into the Recovery System.
    • Click the Utilities menu and select Terminal.
    • Type csrutil disable and press return.
    • Close the Terminal app.
    • Click the Apple menu and select Restart…
  • Open the bear Extender APP installer in BearExtender-5.4.dmg
  • Read and follow the instructions in Instructions.pdf (content of the opened .DMG file)
    Note: At the end of the instructions it says that the BearExtender should reconnect within 7 sec when the USB cable is pulled out, BUT my experience is thet it doesn’t :-(.
    You either need Restart the Mac.
  • Since the application doesn’t install the Kernel Extension at_all/properly we need to do some under-the-cab work.
  • Start the terminal APP from Applications/Accessories
  • Prepare and copy the BearExtender driver to the Extensions directory
    cd ~/BearExtender
  • Open Terminal and type ( or copy and paste) those 3 commands:
    sudo chmod -R 755 RT2870USBWirelessDriver.kext (enter)
    sudo chown -R 0:0 RT2870USBWirelessDriver.kext (enter)
    sudo cp RT2870USBWirelessDriver.kext /System/Library/Extensions (enter)
    cd /System/Library/Extensions ( enter)
  • Clear the kext cache by typing the following 3 commands in Terminal:
    sudo chown root:admin / (enter)
    sudo kextcache -system-prelinked-kernel (enter)
    sudo kextcache -system-caches (enter)
  • Plug the BearExtender to USB and reboot
  • Follow the last paragraph of the instructions on hoe to use the Connection Manager of the Bear Extender
    (Contained in the opened BearExtender-5.4.dmg)
  • Happy surfing
