Q: Bluetooth problem with OSX Yosemite: Magic Mouse and Keyboard

Don't forget your bluetooth antenna may be on your display near the webcam. If you hold down the option key while selecting the bluetooth menu from the top right, you will be able to see the RSSI (received signal strength indication) value.  When my mouse is within an inch of my mini my RSSI value is  -68dBm (decibel-milliwatts). As I move away a few inches until it becomes jerky, it drops to -86dBm. A general indicator is 0 to -60 (good), -61 to -70 (ok), -71 to -90 (poor), less than -90 (really really bad). I am not saying that the low power ratio is the problem here for everyone, but it is definitely very bad for me...

Just a quick heads up, a 2.4Ghz Wifi connection can interrupt Bluetooth, so use 5Ghz if you can.

Hi taris3

distance doesn't make a difference for me but the bluetooth issue disconnected my wifi, I had to switch off my wifi and back on to get a wifi connection again.

I did reset my PRAN memory but this did not resolve the issue. A day later the issue spontaneously resolved itself.

I switched from windows to Apple products 10 years ago but now I am becoming concerned about the reliability of Apple hardware/software. I feel they are chasing after profit more than maintaining quality...... something that would make Steve turn in his grave, hope Tim reads this.... probably not ;-)

Following up on impact of WiFi:

Running iStumbler to monitor my mouse Bluetooth signal strength, I notice significant signal reduction when turning on WiFi, with recovery of strength immediately when WiFi turned off.  See attached listing; the two times I turned on WiFi are at 10:02 and 10:09. Mouse response was erratic at lower signal strength.

2.5 GHz band was being used.

same here.. exact same problem... very disappointing and frustrating. i hope apple has a solution ASAP!!!. and im in kenya no support here whatsoever... only sales. after sales you're on your own. its a petty how apple gives out authorised dealers in kenya, and they dont even give the back up. but dont worry im going to put an article in the papers soon....

Yep brilliant guys. Confirmed exactly the same behaviour. Signal strength degrades significantly the further I am away from my mini. However, once wifi is off (2.4GHz) the bluetooth signal strength is definitely back to normal and the mouse works fine. So now we know why, how do we fix it?

For me, my bluetooth speakers work fine using this sequence:

1. turn off wifi
2. connect bluetooth speaker
3. wait for it to connect (takes same length of time as for Mavericks)
4. switch wifi back on
5. then speaker works fine - very occasionally the music sounds garbled, but mostly okay - and doesn't disconnect when switching wifi back on

if I don't switch off wifi then no matter how close the BT device is to the computer, it doesn't connect

I don't use the magic mouse or bluetooth keyboard so can't speak to the success of this approach for those devices

Hi, the solution is quite easy.  go to system tools, go to Bluetooth, switch off and switch on, your Apple Magic mouse should now be connected, it worked for me! Enjoy Yosemite and your mouse!

didn't work for me

Im also unable to pair my bluetooth mouse with my macbook pro, ever since i installed yosemite. Has apple acknowledge the issue??

I tried this and after my second attempt at it, it worked.

spoke to soon, connection dropped again

kill ur wifi and try again

I Tried that, and it did work! I didn't stay on  long though... we'll see 2morrow
