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

I installed 10.10.1 beta, easy enough.  But we shouldn't really have to go to such lengths.  Apple is dropping the ball on this one,

I Ordered a 2014 Mac mini which ships with Yosemite  and it had Bluetooth issues with the new apple keyboard and trackpad straight out of the box. 4 apple support chats and 2 genius appointments later it was returned as faulty but I suspect Yosemite. PeRipherals are proven to work with iOS8. A new mini arrives monday.. I might send that back too after reading these comments. It has been a frustrating, time consuming (10+hours) and disappointing experience.

there is a fix apparently in beta test, see macrumours. So maybe hang in there for a bit ;-)

Thanks, that worked for me on a MacPro 5,1.

PRAM Reset without removing all BT Connections didn´t change a thing. I recommend the use of a USB Mouse to remove all BT Connections before restarting.

Funny thing was, that my Logitech BT Mouse connected immediatly and was working fine and the MM did not.

I have a new iMac Retina 5K and am encountering massive BT issues with my Mouse. I'll pair it after deleting old instances and it seems to work fine for some time and then if the computer goes to sleep, mouse will act funny. It will have basic two-mouse functionality but scrolling and swiping will not work. BT will say that it is disconnected although it is not completely. At this time, I can't even turn off BT and restart and the only way seems to be to restart the computer. Another thing I am noticing is that while start is super fast but the shutdown is painfully slow - 1- to 2 mins before it shuts down.

Very dissapointed with Apple. I am really starting to wonder because the iOS launch also ompletely bricked my older devices and I am not happy that Apple did not warn the users sufficiently that this may be the case. THese are not isolated cases and the company that we all are so loyal about is not matching up to the high expectations. There has to be a better response. Come on Apple! We deserve better.

Could it have a relation with the battery status? In my case, the battery icon states "Service Battery".

In yes, I have the bluetooth-delay problem with Apple keyboard and trackpad all the time.

I had this same problem, and my new Magic Mouse connects - though not always - when I reboot my Mid-2012 MacBook Pro.  Until Yosemite I didn't have any bluetooth devices, so I don't know about previous behavior.  In any event, the MagicMouse disconnects randomly and then will not reconnect.  This is a very disappointing and unexpected behavior.  I guess I expected more.

Hey, I am finally able to connect a Motorola Silver II BT and stream music to it.  I found 2 solutions that worked for me. No delay and BT mouse and trackpad fine.  No lockups for 1hr+ now.  Fingers crossed.

My Specs:

MB Air Early 2014

Yosemite 10.10

With: Power cable plugged in and on Battery

1.  (streaming from Airport Extreme a,b,g compatible 2.4 ghz)

- I deleted headset from BT

- I went to System Preferences:Accessibility:Audio and checked "Play stereo audio as mono"

- re-paired headset in BT

- headset paired

- hear music now and I was able to select my headset in Sound Preferences

2. (streaming from Airport Extreme n only, 5ghz)

- I deleted headset from BT

- I went to System Preferences:Accessibility:Audio and unchecked "Play stereo audio as mono"

- re-paired headset in BT

- headset paired

- hear music now and I was able to select my headset in Sound Preferences

Hope this helps.  Cheers

Ref previous response, I meant I tried this both with the power cord plugged in and separately on the battery.

The solution for magic mouse was posted above - update to beta. Why people are posting how they manage to connect their Motorola equipment?

This thread about magic mouse isn't it?

My battery is good (late 2013 MBP retina) and still have wifi and bluetooth issue, so maybe not

The beginning of this thread was talking about all BT devices.  Didn't mean to hijack.

All good, it did bring to light the interrelated issues

I tried the proposal from @GLeomode: When the mouse disconnects I switch bluetooth off and after some seconds back on. Then I need to switch the mouse power off and on to put it in the visible/connection mode and select 'connect' to mouse in the bluetooth section. This works reproducible although not satisfying and as said before only as long as you are on a mobile Mac with build in trackpad (I don't know the respective keyboard shortcuts).

Waiting for 'official' the 10.10.1 fix.

I spent all last night re-installing Yosemite CLEAN! And after a while, the Magic Mouse is back jogging, and lagging, and jittery! This is horrible. This is EXACTLY WHAT I FEARED WHEN WE LOST STEVE. I'm not sure what to do with my life anymore. Haha. I'm laughing but I'm serious!
