Bluetooth 4.0 Broadcom Chip Dongle Adapter, Ultra-Mini USB Transmitter Receiver with LED, Support Windows 10, 8, 7, Plug and Play

I purchased this because my Early 2011 15" Macbook Pro only has BT 2.1 and I wasn't able to use it with my Razer Orochi that I received as a gift. Unfortunately it still doesn't work, but I think it's at fault of the mouse and not the dongle. I have been able to connect other devices to the dongle, including older BT version devices. In order to get the dongle to work on a Mac you will most likely have to Bluetooth Explorer from Apple's developer page. It will allow you to switch to the BT dongle from the built in BT. I have also installed a Continuity Activation Tool onto my computer that allows me to enable Airdrop and Handoff on my Mac using this dongle. Older Macs that don't have BT 4.0 built in have these features disabled. The dongle needs a bit of force to insert and remove compared to other USB devices I own. I don't think it's a problem and it probably helps keep it from coming out accidentally. There is a little blue activity light that flashes when in use and is solid when idle. For me it remains on all the time even when the computer is asleep. I haven't experienced reduction in battery life because of it. If you're a Mac user that needs BT 4.0 for something this should work for you just fine and if you're on Windows I highly doubt you'll have any issues due to the plethora of drivers out there.

I have a newer build Hackintosh with UEFI BIOS, with only USB 3.0 ports and running OS X Yosemite 10.10.1. I originally bought the IOGear Bluetooth adapter because it had worked for me in the past with an older hackintosh machine. But on this newer Hackintosh, it did not work at all no matter what I did, neither in Windows nor OS X. I gave this GMYLE Bluetooth adapter a try based on someone's review and it works absolutely perfectly. In both Windows 8.1 Pro and OS X Yosemite 10.10.1, I am able to connect my Magic Trackpad, Wireless keyboard, and every other BT device with ease. It did not require any special Unibeast drivers or anything, simply plug in and pair with your devices. This little thing was a life saver, as I need my Magic Trackpad with OS X, the two are inseparable. If you have a Hackintosh or any computer in need of good quality bluetooth (has great range as well), then buy this adapter!tl;drWorks great with new Hackintosh'sGreat RangeBuy it!

This device, in the pictures displayed for it, identifies it as Mac-compatible with a broad range of Apple product. The literature that comes with it has absolutely no Mac software or instructions to make this work. On my Early 2009 Mac Pro, it required, after no small amount of googling and reading advice (none from the manufacturer), accessing my Apple Developer account to download the latest version of additional tools for Xcode, installing Bluetooth Explorer, and using its HCI Controller Selector command to switch from my built-in older Bluetooth to the GMYLE device. Along the way, I managed to have to force shut-down the computer and swear in several languages before I managed to get it to work. The fact that it now works, and works pretty well, still does not excuse the identification of my machine as "compatible" without providing any information on just what is needed to achieve that "compatibility." Had I known what I was headed for in its successful installation, I would likely have concluded it wasn't worth the trouble.

I purchased this to use Apple Wireless keyboard and the wireless mighty mouse with my Windows 7 Machine. As far as the functionality goes, it works like it should be. Except for two problems....First, when I plug this dongle into USB port ALL THE WAY(like anyone would plug in any USB device all the time), it won't power up. This dongle has a blue LED light indicating that it's turned on, but if I plug this thing into any USB port on my computer, it won't power up. I have to pull it out probably about 1mm to get it worked. I'm assuming that it's not the best of best in build quality category.Second, this could be critical to some. So I got my package and like how I normally would, I started to cut the packaging(not the shipping box, the plastic container that keeps the items, documents, and etc..) and what do I know, I just cut through the installation CD. I was like, you cut this packaging wrong, then you're screwed? Ok...? then I thought oh no biggie I can just go to the website and download the driver from there. Right? Nope. Official website of this product does not have download page for drivers. I thought I was really screwed but I somehow figured it out....If you don't have an optical drive or threw away the CD or destroyed it like I did, try this method. If you connect this to your Windows 7 PC(I don't know about Windows 8, but I would assume it should work since the W8 has much more drivers) it will say that it can't find the driver and it can't be installed. Click on that popup then some box with installing new hardware failed, no driver found with some red signs. In that box, there should be an option that says something like "search in windows update" . Click on that, then voila, it should be working.Now I say this because I find many people turn off their automatic updates or their computer doesn't search in windows update automatically when the driver is not found.Overall, dongle is working perfectly, but I am giving it 4 stars because of the hassle I had to go through and some build quality issue.
