Magic Mouse stops working under Yosemite

Mine too, also since Y10.10 upgrade. Mine reconnects a few seconds later but its still very annoying.

I am having similar issues with my MM and 10.10. Put in fresh batteries and still a problem. Loses connection/slow erratic cursor movement.

Mac Mini Late 2012 16 Gigs of RAM, two 1 gig drives, dual monitors, wired apple extended KB and now a wired dell mouse.

Face time has issues, also. for another forum...

I have the same issue with my Magic Trackpad. It seems to only happen when I put my laptop to sleep and then open it back up later. Then my Trackpad won't connect and the only solution is to reboot. I have tried deleting it from my bluetooth devices, rebooting, and repairing it, but still happened again today. Please help Apple!!

I am having the same problem. My mouse is not usable with the new OS.

I just got a new iMac with 5K Retina display and the same thing happens.

When the computer sleeps the keyboard and mouse won't reactivate it. So I press the power button and it comes on instantly. But from then onward, until I reboot, the Magic Mouse scrolling functions, and wireless keyboard special buttons (volume, screen brightness, media controls) no longer work.

Hopefully there will be a fix for this soon!

Same problem here... What worked for me, as someone else mentioned, was to turn off WiFi and then connect to the mouse through the Bluetooth menu. Once connected, you can turn WiFi back on.

MacBook Pro (Retina, 13-inch, Early 2013)

OSX Yosemite 10.10.1

Me too, with 10.9 it worked perfectly, but now it sometimes disconnects and the only way to reconnect it is to put the mac in stop, turn off the mouse, and if i'm lucky it works, otherwise I have to restart the mac. What should we do?

I had to restart my MBPR 15 (early 2013) OS X 10.10.1 when my mouse started to not connect. My problem was every time I came back to work the mouse would not connected until I restart. But when I turned the wifi on and off like mikaey suggested, then my magic mouse was magic again, lol. I wonder if the software engineers at Apple will look into why when you turn the wifi on and off; that makes the bluetooth mouse work again?

I'm in the same boat. Lost power and had to restart. MM gestures work but only if I bring up a new Safari window. If I try to "back page" with a swipe, the gestures all lock up. Two finger gestures are unresponsive completely. Got kind of spotty when I went to Yosemite, but now I'm back to menus and buttons. God I'm spoiled.

If you have installed or Updated VirtualBox, just inistall it, I suffered same issue yesterday, this solved it .

I've experienced similar loss of 'clicking' e.g. the mouse keeps moving around fine but the clicking has no effect.

Since the keyboard still functions, I found a workaround that's a little less tedious than a forced hardware shut down:

I press <SHIFT> <CMD> Q (shift, command, Q keys) to do a LOGOUT. When I LOGIN, the magic mouse is back to normal

I'm experiencing the exact same thing. My bluetooth will either stop working in the midst of working, or won't re-connect after my MBPro wakes up. I turned off then turned on wifi and it works. My wifi also stops working occasionally. Hopefully the release of 10.10.2 will solve these issues.

I have... I have a brand new Macbook Pro 15", 16GB, 512SSD. Reset everything, repaired it with the MB.... Then

Double check any other computers in your house. It had been paired with another Mac at one time, and so it would get it first.

Would be nice if there was a hard reset in the Trackpad itself (hold power for 10seconds, light blinks in some long short pattern) that remove ALL pairings so you could start back to the one machine you wanted it paired with.

But, until then, Walk around and check if you're moving someone else's mouse cursor 😀

Very bizarre solution, but it works! Hopefully this is an issue Apple is aware of.
