Bluetooth problem with OSX Yosemite: Magic Mouse and Keyboard

I had the same issue and it seems to be fixed since 2 hours now after some action:

1) Disconected mouse and keyboard

2) Delete mouse and keboard from bluetooth paired device (nothing left)

3) Shutdown

4) Reset PRAM

5) Restart and resync mouse

Same here. I too reported this issue build after build, but to no avail... Very upsetting. On a Mac Pro, 2010.

@DanOsers,

I had a iMac 2013 with Yosemite and no bluetooth problem. I now have a iMac 2014 5K and struggling with bluetooth issues. Even a clean install did not solve this. Wondering why not all iMac 5K users are not affected.

I started a new thread for this problem on iMac 5K here iMac 2014 5K Bluetooth Trackpad Problem after sleep

(I thought the Macbook Pro problems are due to Yosemite and iMac 5K has a different issue. It however appears to be the same)

My magicmouse is now connecting immedeately after start/restart, it seems that the problem is solved after SMC/ PRAM reboot. I did this several times but at last it had effect.

Hi,

I don't think the link is working, but I'll do a search on the board.

I had some success with more data points on the BT issue on the iMac; When waking the system from deep sleep with ANY BT device, the issues occurs, and is reproducible 100%. However, if I initiate wake with the power button, BT initializes fine, and there are no issues.

from the BT diagnostics it would appear that the power states of the broadcom chip isn't activated correctly when BT wake occurs (and hence duplex communication is limited, and information such as scaling, battery levels etc. all don't work until a hard reset).

I did file a bug report with Apple on it.

Sorry about the link. Here is it again https://discussions.apple.com/thread/6642423

My finding is exactly same as yours. The problem is only present if the iMac is woken up with a bluetooth peripheral.

I am only wondering how all iMac 5K users are not affected by this. If it has something to do with certain iMac hardware, I want to make use of my return period to ask for an exchange.

a PRAM reset did not fix my issue, it just came good one day while working on my macbook. All was good unit I restarted it now the magic mouse is jittery until I switch off wifi, if I switch wifi on again the issue returns. Also I can't connect to my wifi network, I can only use my thunderbolt ethernet

PRAM reset did not fix my issue, jittery magic mouse, can't connect wifi but mouse ok if I turn off wifi. but after holding down the off button and forcing a restart it has come good..... for now

I found the way to work in closed shell mode:

I downloaded 'blueutil' tool and put a Terminal in my Dock

When mouse stop working I press CTRL-FN-F3, I open the Terminal and type 'blueutil off && sleep 5 && blueutil on'

Still waiting for a permanent fix from Apple

Same Bluetooth connection loss issue here after Yosemite update - MBP13'' retina while working suddenly lost the connection to Magic Mouse or Trackpad.

The blueutil as proposed by @GLeomode does nothing else than switching bluetooth off and back on. That worked for me in rare cases (luckily you still got the build in trackpad on the MBP). All other hints (PRAM/SMC reset, disk repair) will only work temporary.

Typically I need to reboot - currently at least once a day. I am feeling close to my old Toshiba Windows machine that made me switch to the Mac six years ago.

Yes it is unfortunate that Apple is following in the path of Microsoft...... with updates now introducing more issue than benefits. I will now adopt my upgrade tactics from my microsoft days and wait a couple of versions before upgrading. My wife's MBP on Maverick works fine!!!!

I feel that the resent success of Apple has made them slack and loose sight of Jobs objectives of providing quality hardware and software... at a premium price. Well that premium is becoming much less worthwhile these days. Are there any companies on the horizon like the old Apple?

Also, i think there is an update coming that is in beta testing, will see what it fixes and what it breaks

by the way, I am still waiting for my iPhone 6 128Gb..... think Apple has lost the plot or maybe just focusing on the Asian market and forgetting about Australia.

The Samsung Galaxy is looking rather attractive, and the Sony Vivo as well ;-)) seriously

Hi guys, I'm currently testing 10.10.1 for almost a day and definitely the BT bug so far haven't showed up. I'll keep you guys posted.

I'm having the same problem. About a 0.5 sec lag on magic mouse when 13" Retina Macbook Pro is on battery.

It is driving me nuts. My laptop has gone from being a joy to use, to a frustrating pain.

Have tried the various solutions suggested in the thread, but none have made a difference.

So it's good to hear that is might have been fixed in 10.10.1. Anyone have idea when that might be available?

This morning suddenly my Magic Mouse stopped to work. I thought it just broken. I even disassembled it but I shouldn't because It's not that easy to reassembe it again to be that neat as it was. So think twice before you do it.

Anyway, my solution: I removed the mouse in Settings » Bluetooth then rebooted and added the mouse again.

Everything returned to normal, reconnetcs and works as it was (reconnetcs, fast etc). What was annoying that along with the bluetooth issues I experienced wifi problems, drops and disconnetcs.

I am on OS X 10.10 (14A389). Hope this helps.
