I followed all the directions and the dongle (IOGear one) is recognized and is working (paired with a Magic Mouse no problem and the Broadcom shows up in the Bluetooth hardware section on the system). The only hitch is that when I option-click on the Bluetooth icon, it still says version 2.4 (as its does in the system profiler), not version 4.0. I don’t have any 4.0 devices handy to check, since I want to make sure this fix works before I drop the money on the fitness sensors that I’m going to be using. Anyone have any thoughts about this discrepancy?

I was editing the Info.plist in /System/Library/Extensions/IOBluetoothFamily.kext by mistake instead of the one in BroadcomUSBBluetoothHCIController.kext. So make sure you navigate through to the Plugins folder to find the correct Info.plist Also, my Broadcom kext had a slightly different name, but it was pretty obvious Integers for the ASUS USB-BT400 are 6091 and 2821, so the code to insert is: Bluetooth 4.0 USB Dongle CFBundleIdentifier com.apple.driver.BroadcomUSBBluetoothHCIController IOClass BroadcomUSBBluetoothHCIController IOProviderClass IOUSBDevice idProduct 6091 idVendor 2821 •. Hi Ken, So, I just ordered and received my IOGear GBU521. I’m trying to allow Bluetooth 4.0 with my 5,1 Macbook late 2008 Unibody, running Yosemite. Last night I plugged it in, and within a few minutes suddenly I couldn’t access the internet.

Shop for usb bluetooth adapter at Best Buy. Find low everyday prices and buy online for delivery or in-store pick-up. Hello everyone, I bought a Bluetooth dongle today but no drivers for Mac were included. After searching the web to figure out how it can work on Mac, I found this article.

Hi Ken, Thank you for this. I purchased the iogear 4.0 dongle and tried it last night on my Mac pro 1,1 running Lion 10.7.

However, I’d advice you to try editing it yourself to be familiar with the process since every OS X update is likely to ‘wipe’ off your hacked ‘kext’ and you’d need to re-do the steps again, and it’s always best to edit it from the latest kext file. Once you have the edited kext.

Unfortunately, although I can see the dongle in Bluetooth Explorer, when I try to activate it it just turns off Bluetooth. I’m trying to check if the dongle might coincidentally have gone faulty but seems unlikely Any suggestions? Hi again in a mac mini core solo 1.5 update to 2.0 core 2 duo and mac os x 10.6.8 and 2 gygas of run insert the BELKIN v4.0 adapter in the usb rapid port Set the instruction and download use the sample edited kext file in this page and finally drag to kext utility, working on this, repaire permissions, close the app and restard.

IOGEAR GBU521 Bluetooth 4.0 Micro Adapter Why I even explored getting a Bluetooth 4.0 USB dongle was due to the untimely demise of the onboard Bluetooth 2.1 chip on my 2010 MacBook Pro. It just went dead without any warning after about 1.5 years of me using my MBP. So I searched for a Bluetooth dongle that has Mac support. You’d be surprised that there isn’t many that officially states OS X support, especially so for a Bluetooth 4.0 dongle. So in the end, I decided to pick one that apparently used a photo of the dongle (see below) plugged into a MacBook Pro and hoped that it would work. If you’re wondering which Bluetooth 4.0 dongle I bought, this will bring you to the item page on eBay and it cost me US$12.98 for the dongle.

When finish, just quit the Kext Utility and reboot your system. Once restarted, your Mac should now recognize the new Bluetooth device and you’re good to go! But to make sure that the new dongle is the active one being use, hold on to the option key and click on the Bluetooth icon on the menu bar. If you see the version to be 4.0 then you’re ok.

• The recommendation is to look for dongles based on the Broadcom BCM20702 chip, which are similar to the ones used by Apple in their Continuity compatible Macs. A few examples: Asus BT400, IOGEAR GBU521, GMYLE, and many others.

Thanks for posting your information about getting the bluetooth dongle working!! I had the same issue – couldn’t get OS X to use an iOGear GBU521 instead of the iMac’s built-in BT chip. Hi Ken, Thanks for an in-depth and informative post.

I also don't want to have to take up a USB port by getting a Bluetooth 4.0 adapter. Are there any Bluetooth only cards I can switch my only current card for? I saw just Mac Pro Bluetooth replacement cards selling on amazon but they were Bluetooth 2.0, not 4.0.

Then, once the Pro was powered back up, I had to plug the magic mouse into a usb port with a lightning cable for the system to recognize the mouse on the new bluetooth radio (which is plugged into my wired (numeric) keyboard). Once I had the mouse working, I could re-pair my magic trackpad also. Did I mention that I'm happy as a clam.

To use Bluetooth, first you must turn it on.” The Bluetooth status in the menu bar says it’s on, though, and you can still click “Set Up New Device” in the Bluetooth pane in System Preferences, but it doesn’t find anything. I did get it to connect to my phone, and was able to transfer a photo back and forth, but I can’t seem to get it to work again. Any suggestions? I’m new to using Bluetooth–maybe I’m just not doing something simple? I am on Mavericks on my slightly older iMac. I am using the same dongle you are. I found that: 1.

Apple suggests replacing the airport card – which is a pain. To use the Bluetooth Explorer on El Capitan you have to download an addon package for xcode called “IO Hardware Tools For Xcode 7” from the site. For this you need a developer account which, to my best knowledge is still free to aquire. Perhaps the author of this fine how-to will be so kind to update it with this information and maybe even upload the Bluetooth Explorer app right here, for the convenience of the future readers. Without BE one cannot select the controller, rendering the dongle unusable. Hi – I used the kext edit advice to get an ASUS USB-BT400 to work on a mid-2007 iMac – thanks for that!

Compatibility with CSR dongles is not guaranteed. • Instant Hotspot currently doesn't work reliably when using a dongle.

Of course, all devices have to be in the same room and should have a good connection between each other to do so. That technical background should do for various nifty little gimmicks.

It is a Bluetooth 4.0 adapter that works with a PC or Mac. It also support most any Windows operating system, Windows 8, Windows 7, XP, Vista, 2003, 2000, Me 64/32 bit Summary Adding Bluetooth compatibility to a non-Bluetooth computer is a easy processes that most anyone can do. Simply need to be plugged in and will work automatically. When buying a Bluetooth dongle simply be sure it is compatible with your version of Windows.

Except it doesn’t quite work for me OSX 10.6.8 on a mid-2007 MacBook (version: 2,1). I had to use KextBeast to get the modified kext file to load. Same iogear BT USB as mentioned above and with the same product/vendor as your screenshots and sample file. When I plug in the BT USB, the mac’s profile says it goes from Bluetooth LMP 3 to 6, which i think means it can handle BT4.0. However, the BT icon on the mac bar still shows 2.4.5.

Bluetooth 4.0 USB dongles A few important notes about using CAT with USB Bluetooth 4.0 dongles: • Bluetooth 4.0 dongles based on the Cambridge Silicon Radio CSR8510 A10 chip (e.g. Inatek Nano) are not compatible with CAT.

• Atheros Wi-Fi AirPort cards will prevent Continuity from working even when adding a Bluetooth 4.0 dongle. The System Diagnostic feature of CAT tells which Wi-Fi brand is active. There are no workarounds and no patch is expected to change this, an AirPort card upgrade is required.

I needed to download the Bluetooth Explorer from developer.apple.com. (It is in the download called “Hardware IO Tools for Xcode.) 2. It seems to stick across reboots!!! This makes “knocktounlock.com” work on my older iMac which is why I was going through this in the first place. CAUTION: Have a wired keyboard and mouse on hand. Switching BT adapters unpairs your BT devices from your mac, and if you only have a BT Keyboard and BT Mouse/Trackpad, you’ll be hosed. First off, great post.

I went to sleep, woke up and tried again. The wifi was working again, so I then ran the utility and reloaded Yosemite. After a few hours, I was in business with my restored hard drive and no loss of info! So now, I’m wondering if the dongle caused all of this?

Hi, Thanks a lot for this very useful and instructive post. I have a Magic Mouse 1 and a Mac Pro 3.1 under El capitan 11.6, and a Belkin F8T065 dongle plugged in the cable keyboard.

After installing the IOBluetoothFamily.kext file, for some reason MBP’s in-built Bluetooth adapter has become unavailable in the top bar. Also I can no longer see the “Bluetooth” icon in the system preferences. Surprisingly though I can still use my wireless keyboard; hence the actual Bluetooth adapter seems to be functional.

So unless being a little ‘bling-bling’ is your thing, get the which looks a little more discreet. Also, you can sometimes get pretty good deal on Amazon and get this dongle for as low as US$13.50. But of course any Bluetooth 4.0 USB dongle would do as long as it is using the exact same chip as the IOGEAR’s dongle, which is Broadcom’s BCM20702A0 chip. You can read more about the chip. Now, you’d probably guessed that the dongle didn’t work right out of the box, hence this article. When I plugged in the dongle, Bluetooth support was nonexistent. However, the USB dongle did register up in the USB Device Tree when I checked with the System Information.

Hey guys, I've looked and can't find a thread for this but I have a Mac Pro 4,1--> 5,1 and I want to be able to use continuity and air drop. For this I have to have Bluetooth 4.0 BLE. I JUST bought a new AirPort Extreme card for my Mac Pro so I really don't want to have to buy the 2 in 1 Bluetooth airport card. I also don't want to have to take up a USB port by getting a Bluetooth 4.0 adapter. Are there any Bluetooth only cards I can switch my only current card for? I saw just Mac Pro Bluetooth replacement cards selling on amazon but they were Bluetooth 2.0, not 4.0. Anyone have any links to one or know where they can be purchased?

This time, the Mac wouldn’t turn on So I reset and opened Safe Mode. No problem there, but still not connecting. So I restarted again, and this time got the grey screen of death and the 0/ symbal (put the line over the circle like Ghostbusters) and couldn’t get anything to work. I fixed permissions, I tried safe mode again (wouldn’t work).

Please see below. BCM20702A0: Product ID: 0x21e8 Vendor ID: 0x0a5c (Broadcom Corp.) Version: 1.12 Serial Number: 000272328D26 Speed: Up to 12 Mb/sec Manufacturer: Broadcom Corp Location ID: 0x5d100000 / 2 Current Available (mA): 500 Current Required (mA): Unknown (Device has not been configured) Not sure how to get the dongle to work. Any good ideas? Cheers, JuPe •. Thanks for the info, this is exactly what I need. Except it doesn’t quite work for me OSX 10.6.8 on a mid-2007 MacBook (version: 2,1).

I recently started playing around with one of those RFDuino’s. These are microchips with BLE built-in and with the Arduino framework built around it. It’s easy to connect them to a iOS device, but if you want to connect them directly to your Mac, it’s a little bit harder. One of the things you’ll need, is BLE support on your Mac.

And if you’ve gone ahead to open up the Info.plist file, you’ll then notice that the idProduct and idVendor values are in integer. So you’ll need to convert it from hex to integer. In my case with the BCM20702A0 chip, the Product ID value is 0x21e8. Converting 21e8 to integer gives me the value of 8680. As for the Vendor ID, 0x0a5c is 2652 in integer. If you don’t know how to convert hex to integer, just use to do so.

It said version_LMP=0x6, and I recognized the belkin informations in the sys info. It WAS working because my mouse did reconnect and finally recognized the new dongle. Handsoff still does not work! In system informations, near to “Handoff pris en charge” (means handoff taken into account in english) it says NO And I do not have any toggle in System preferences/General. Is it that my Mac does not want this particular dongle for handoff? I’ve been looking at the Yosemite’s kext file and it seems that it’s even more comprehensive compared to the one in Mavericks. It the IOGear GBU-521 (and even the GMYLE one) officially listed!

Once you choose the USB dongle as the BT device, the internal one will be disabled automatically. If you expect to CAT, then you can follow this guide from CAT webpage.

What OS X cares about is only the idProduct and idVendor keys as that’s what it uses to match and load the appropriate drivers. Microsoft Bluetooth 2.0 USB Dongle CFBundleIdentifier com.apple.driver.BroadcomUSBBluetoothHCIController IOClass BroadcomUSBBluetoothHCIController IOProviderClass IOUSBDevice idProduct 156 idVendor 1118 Bluetooth 4.0 USB Dongle CFBundleIdentifier com.apple.driver.BroadcomUSBBluetoothHCIController IOClass BroadcomUSBBluetoothHCIController IOProviderClass IOUSBDevice idProduct 8680 idVendor 2652. If you aren’t sure about this, you can use the sample edited kext file here –. You could use my kext file right off the download. However, I’d advice you to try editing it yourself to be familiar with the process since every OS X update is likely to ‘wipe’ off your hacked ‘kext’ and you’d need to re-do the steps again, and it’s always best to edit it from the latest kext file. Once you have the edited kext.

It just went dead without any warning after about 1.5 years of me using my MBP. So I searched for a Bluetooth dongle that has Mac support.

If you’re wondering which Bluetooth 4.0 dongle I bought, this will bring you to the item page on eBay and it cost me US$12.98 for the dongle. And jumping ahead, it works, so you could go ahead and get the same too, especially if you decide to use the same kext file that I’ll post up in this article as a sample.
