Apple has released a new support document that says unreliable Bluetooth wireless performance may occur when USB 3.0 devices are nearby.

Symptoms
Bluetooth enabled keyboards and mice may not pair or connect consistently, or audio from Bluetooth enabled earphones or speakers may be choppy. This can happen if certain external USB 3.0 devices are too close to your Mac.

Resolution
● Try moving external USB 3.0 devices further away from the computer, and away from your external Bluetooth devices. For example, if you think an external USB 3.0 hard drive may be causing an issue, try relocating the device away from your Mac or move it to another side of your Mac.

● Make sure all USB cables are connected correctly. Better shielded USB 3.0 cables may also be helpful.

NoGoodNick: we will see. But if you read, it reports USB 3.0 may affect your Mac? That makes me believe the Mac cannot shield USB 3.0 from overpowering or disrupting the Mac's Bluetooth signal. So the Mac's Bluetooth may have a problem with the USB 3.0 signal. USB 3.0 is a standard; it should work on anything that has USB 3.0. Apple just wanted to tell the world first that your USB 3.0 Bluetooth headsets and keyboards may not connect to your Mac; move it away and it may be better. 'You're holding it wrong, get a bumper, it just works.'

Any wire except optical fiber have inducted electromagnetic camps, USB3.0 have more power that 2.0. I live in a house in Portugal with high tension wires crossing up the house and any bluetooth device in my house works. My wifi network is a router and a repeater in any compartment and 3 in the living room, to have 2 or 3 wifi bars. I have 2 windows pc's, a macbook pro and an ipad in the house, and windows pc's with wifi-a,b,g,n are horible to maintain wifi connections and the mac and iPad are better. I like windows 8 more then mac os x, but apple hardware are much better.

My windows 8 laptops are experiencing the same issue with Bluetooth. I guess that really throws a wrench into the theory about apple having shitty products.

This is hardly Apple only. This is likely to impact Any USB/Bluetooth device. Blaming Apple for physics problems with independent hardware simply because they were the first to report it is just juvenile.

Oh no, not another issue? What do Apple's testers do? They don't seem to test much at all. Or is it that Apple doesn't care and just puts stuff out anyway?
