Finally got this to work for ME this week. I have an early 2011 13" MBP (A1278) running on the latest updates of OSX High Sierra. I used the the Continuity activation tool because I couldn't delete the IO80211Family kext extension. I copied and modified the IO80211 file on my desktop, deleted the extension from the library and ran Kext Drop, I reset my Mac and it worked flawlessly with my iPhone 7 plus and iPad Air 2.

Update (15 Dec 2017) - MacOS 10.13.2 update disables Handoff, but I was able get Handoff/continuity working again by repeating the steps. So far this guide still works on the latest updates to MacOS.

Update (09 Jan 2018) - MacOS 10.13.2 Supplemental Update - I just installed this latest security update and good news the update did not disable continuity on my machine.

Download latest beta of Continuity Activation Tool
When the trigger was started activation tool, a message ran outafter, then must be disabled SIP.
Reboot the Mac and hold down Command + R keys simultaneously after you hear the startup chime, this will boot OS X into Recovery Mode. OS X Utilities -> terminal and following command into the terminal - csrutil disable
After I disabled SIP running activation tool correctly. Everything works as it does with tablet and iPhone.

Following the instructions here I installed the updated card (see pic) in my Early 2011 MacBook Pro 17".


Initially on reboot it asked me to reset the clock which I did

WiFi works OK

However Bluetooth does not. I get Bluetooth: Not Available when clicking on the Bluetooth icon on the top bar. The Continuity Activation Tool confirms this


I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from the Library/Preferences folder and rebooting after complete shutdown and have done an SMC reset all to no avail

Specs as follows:

Model Name: MacBook Pro

Model Identifier: MacBookPro8,3

Processor Name: Intel Core i7

Processor Speed: 2.3 GHz

Number of Processors: 1

Total Number of Cores: 4

L2 Cache (per Core): 256 KB

L3 Cache: 8 MB

Memory: 16 GB

Boot ROM Version:

SMC Version (system): 1.70f3

Serial Number (system): XXXXXXXXXXXXXXX


OS: HighSierra (10.13.6)

Any suggestions

Guys, I need your help because nobody within a few hundred miles understands anything in Mac.

I replaced the bluetooth / wifi module on my macbook pro early 2011 and now it doesn’t work properly.

When trying to connect to wifi, an error "wrong password" occurs: and if a wifi network without a password - it simply cannot connect to it

when connected via Personal Hotspot on iPhone mode it works!

Same issues with BT: it finds bluetooth devices but cannot connect to it

What should I check first?

Thanks guys, finally I know how to do it right. Below is my steps:-

1) open Terminal type sudo nvram boot-args="kext-dev-mode=1"
2) reboot your MBP
3) your wifi will not be working at this moment, replace the file IO80211Family.kext in Go>Computer>System>Library>Extension
4) open Terminal type as below:-
sudo chown -R root:wheel /System/Library/Extensions/IO80211Family.kext
sudo chmod -R 644 /System/Library/Extensions/IO80211Family.kext
sudo kextcache -system-prelinked-kernel
sudo kextcache -system-caches
5) now reboot your MBP again.
6) now you will see System Preferences>General> will have handoff enable option
7) open Terminal type kextstat | grep AirPort

Now you will see
kextstat | grep AirPort
130 0 0xffffff7f82c62000 0x5df000 0x5df000 com.apple.driver.AirPort.Brcm4360 (900.14.2) <129 47 46 12 7 6 5 4 3 1>
133 0 0xffffff7f83241000 0x1f3000 0x1f3000 com.apple.driver.AirPort.Brcm4331 (800.20.24) <129 46 12 7 5 4 3 1>

You're DONE :) Cheers.

Once I realized that I needed to disable the System Integrity Protection it worked!
Thank you!!
