And what have you do with this kext? Only install with kext drop and execute the terminal commands?
Click to expand...

First I found the Kext that i needed here: https://www.dropbox.com/sh/sblm1kdnd4ga941/AADwVhbNhzaMSaj3xqhTkBoEa?dl=0

Then followed these steps that Lem3ssie made:


  1. Delete IO80211Family.kext from /Systeme/Library/Extensions


  • Reboot, wifi is now dead.


  • Copy unzipped IO80211Family.kext to /System/Library/Extensions


  • Terminal this
Code: 
sudo nvram boot-args="kext-dev-mode=1"

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

What is the LMP-version of your bluetooth card? you can find it in "about this mac", the place you found your bluetooth-software version

Then you can't get handoff to work. If you had read the thread you would have known that you need to make a hardware upgrade first.
Click to expand...

I thought i have read, that a guy with this has handoff running. So no chance for the hardware?

Ok - thanks!

You can send SMS and make calls on your hardware, but Handoff will only work if you buy a new bluetooth/wifi card, to a card that has Bluetooth 4.0.

In my case the card I bought had the model number BCM94331PCIEBT4CAX, where the original card in my MBP 13" was BCM94331PCIEBT4AX (without the "C").

The "reboot - wifi now dead" step was essential for me, and is missed out of doktodok's instructions. I recommend adding it!

agreed. And, of course, Lem3ssie, for putting up with so many requests for kext edits and whatnot

----------

people will probably try the steps that the article lists out, **** it up, and end up on this forum asking for help fixing their missteps

Hi,

Thanks for this. So the new modul has a cost of about how much?
Where can i find a good reseller?
Is a change easy?

wifi and bluetooth crashed

dokterdok said:
Good news for 2011 MacBook Air and 2011 Mac mini owners, here's a refreshed tutorial that enables Continuity on those machines as well. No hardware upgrade is required on these Macs. Handoff, Instant Hotspot, and iOS↔OSX Airdrop now fully work. I've tested it with Yosemite GM (14A379a).

The tutorial is built on top of previous great tutorials made by forum members mikecwest and Lem3ssie (thanks guys!).
The new steps basically disable a blacklist in the Bluetooth drivers.

Update 20.10.2014: UncleSchnitty has posted a complete, up-to-date guide with a more detailed tutorial and extra troubleshooting steps. Good stuff. I recommend you head over his post instead of mine if you want to give the tutorial a shot. Tip: carefully read the whole thing first, don't rush, and stick *exactly* to what is written.

TUTORIAL

1. Download and install 0xED in your Applications folder, you can get it from here:
http://www.suavetech.com/0xed/

2. Download and install KextDrop in your Applications folder, you can get it from here:
http://www.cindori.org/software/kextdrop/

3. Open Terminal and type :
Code: 
sudo nvram boot-args="kext-dev-mode=1"

4. Restart your machine.

5. Open Finder, type CMD+Shift+G and go to /System/Library/Extensions/

6. Copy the files below to your desktop and then delete the originals. Make an extra backup copy of the 2 files in a separate folder just in case.
Code: 
IO80211Family.kext
IOBluetoothFamily.kext

Hello,

I've just done the first 6 steps. My wifi and bluetooth in the menu bar says "no hardware installed". I'm really freaking out. I don't want the handoff anymore please someone just help me get my wifi and bluetooth back. Thanks.

That second article is like a step by step for disaster. It also implies that 2011 machines are doing those steps to "upgrade" to 4.0LE. What uninformed garbage.

Also thank you for originally getting this going. I think because you and everyone on that list were open to helping each other we were able to get this down to a science very very quickly.

Wanted to also thank everyone who made this. You just saved a bunch of us quite a lot of money for something that should have been integrated in our computers.

So who's got the chops to write a script to do this (like Trim Enabler does for the SATA driver) so we can easily do this after each OS update without breaking out the Hex editor?

Thanks to those that have contributed thus far; I'm planning on tackling after my Yosemite upgrade.

I don't think "who's got the chops" Its more like "who would be nice enough to write a script for this because for a lot of people this is a difficult task" and to that I would be willing to wager it won't be long now, at all.

Tried twice...

I've tried the instructions twice, still no handoff option in System Preferences -> General. I did see this when I ran one of the commands, might this be an issue?

$ sudo kextcache -system-prelinked-kernel
Password:
kext file:///System/Library/Extensions/JMicronATA.kext/ is in hash exception list, allowing to load
kext-dev-mode allowing invalid signature -67061 0xFFFFFFFFFFFEFA0B for kext IOBluetoothFamily.kext
AirPortBrcm4360.kext is not valid; omitting.
