Apple Bluetooth 4.0 Adapter

I bought Waves NX Head Tracker to use it with Logic Pro X in a Mac Pro Mid 2010 OS El Capitan and Bluetooth 2.1 I needed Bluetooth 4.0, so I bought this StarTech adapter. Plugged into my computer, but it was not recognized as BT 4.0. Then I downloaded Hardware_IO_Tools_for_Xcode_7.3.dmg, and installed Bluetooth Explorer in the Applications folder. Opened it, Tools menu and choose HCI Controller Selector, I clicked at the arrows and selected Broadcom Corp and clicked Activate. Done My computer recognized the StarTech adapter as Bluetooth 4, and I was able to use my excellent Waves NX Head Tracker.

I have an iMac from late 2009 and by bluetooth was not totally compatible with the Magic Track Pad 2. Before ordering the trackpad I researched on the internet, spoke to people at Apple and B&H. What I got was varying opinions. What I concluded was that I should spend the extra money. When they arrived I paired by trackpad to my iMac without the adapter. It worked initially. But when the iMac went to sleep, the pairing was lost. I hooked up the adapter and since then the trackpad and iMac are happily paired. One last comment. Since I bought from B&H and live out of New York State, there was no sales tax. That combined with the lower price for the trackpad at B&H, I saved money versus driving to the closet Apple Store. Thank you B&H!

Mini USB Bluetooth® 4.0 Adapter is a fantastic product! Better working range than other Bluetooth receivers/transmitters. Works great with Sony MDR-10R after checking ALL of the configuration for USBBT1EDR4. You MUST install ONLY the last version of the CSR Harmony software; if you have an older version installed, you MUST uninstall the older version first. The new version unfortunately does not include drivers for all of the older transmitters and you can't have more than one version installed at the same time. I highly recommend this product.

I didn't like the Apple bluetooth mouse so I bought this one and it works just fine.

Worked perfectly from the get-go and was way less than the Apple version of this adapter.

apple's cheapest adapter works

If you use the apple headphone adapter, you can also use it with iPhone X

You may want to consider a Bluetooth adapter for your headphones rather than this. They are harder to loose and more convenient.

Used it with apple TB to ethernet adapter

This adapter simply works like all my other Apple power adapters.
