Bluetooth problem with OSX Yosemite: Magic Mouse and Keyboard

Just wanted you to know the naysayers of your suggestion are wrong. After my bluetooth mouse dropped out. I tried to reconnect it to no avail. I turned on the wifi and it immediately reconnected. I'm talking within the second.

Hi there

Had success with my setup

My OS x is on a OWC 480GB SSD PCIe card in No2 slot (my system flies). There is a USB 3 and eSATA port on that card which i connected using eSATA, a Crucial 500GB SSD in a OYEN Digital Mini pro USB 3 eSATA case for audio samples . Everything works great except it's what's causing my mighty mouse problems, took it out and mouse ok, have ordered a new eSATA cable which could be the problems (hopefully) and will try again.

Wifi OFF and ON again works. Agreed. It works for me also. Simple and direct, if a little annoying.

Same with me. Not only the mouse, but the keyboard too is not recognized. This has just arisen the last few days, but I updated the OS when it came out. Very frustrating. I've has iPad issues with wifi, which is the subject of many posts, but now with the Macbook too. This is so unlike Apple.

Another with exactly the same issue. The BT Mouse was fine on Mavericks, but now keeps dropping the connection on Yosemite. It's infuriating.

Amusingly, booting up Win 7 under BootCamp, the BT Mouse works perfectly.

10.10.1 is out. Thread is going to be dead soon 😉

Just installed 10.10.1 but still have issues. I'm using the Wifi hotspot feature at work to connect my iPhone while being connected to internet through cable. When disabling Wifi my bluetooth connection seems stable. At home I'm using just wifi to connect to the net, and there i don't have any problems using my magic mouse. So the problem is still not fixed completely.

My mighty mouse will often not work now. I am having to use my Wacom tablet as a mouse which is ok. I can scroll with the mouse but little else

yup, updated to 10.10.1 and still having glitches with the bluetooth mouse. That is very frustrating.

Hi all,

this is a massively annoying problem, but I wonder whether that's really Apple. I went through all the steps all the others did - PRAM reset, etc., installing 10.0.1 - and each time I had the impression, the problem is gone. Yet, it always came back to a degree where I could no longer write anything really. This morning I had yet another idea. Before, I was suspecting it to be some interference with a USB 3.0 hub that I've added, about at the time when the problems started. So I've a Macbook Air which sits behind my 27'' display, and then from that display I've a thunderbolt cable that goes to my Belkin TB hub that is under my desk and that from there branches out to my CD drive, my USB 3.0 hub, etc. - those things are essentially behind my back.

What I had observed is that when those problems start, and the mouse gets jerky or the keyboard starts to have keys that get "stuck" - it sometimes helps to move those things around a couple centimeters. So in a way that might be Apple's way of telling me to move myself a bit to keep healthy? As I am a very fast typer, if my keyboard is lagging behind and then even starts repeating characters, that's really really really annoying and makes me feel of like 30 years ago.

Also, was helped from time to time was to disable bluetooth, even removing and re-adding the device that has problems - e.g. the trackpad.

All of that very inconsistent behavior, difficult to track down.

So back to this morning, when I had my shower and was listening to some internet radio using my IPhone, I thought, wait, what else is there that I've lying behind my back normally? Right, my IPhone. connected to the charging port of my USB 3.0 hub. So what if I do not have USB 3.0 interfering with Bluetooth, but my WLAN?

I have, essentially in a straight line, 2 meters behind my display, one of my WLAN Access Points. So I remembered that somehow around the time those problems started, what I did also do was to replace my old APs with newer Nighthawk X6 R8000's. I do know that the 2.4 GHz bands may interfere with Bluetooth, but just didn't try it.

So I went to the web interface of that router, which of course has no option to disable the 2.4 GHz band. Anyway, I telnet enabled the router and then went on it using telnet and just did an ifdown eth1 (I had identified the MAC address of the 2.4 GHz module using WIFI explorer). Notice that while my Macbook is connected to my display, I of course do not even use WLAN on the Macbook since I use the Ethernet port on the Belkin hub.

Two things happened. First of all, my Internet radio stopped playing on my IPhone 4s. Of course, because it only speaks 2.4 GHz. So maybe there's finally a reason to go shopping for a newer model.

More importantly, the Bluetooth problems are gone - since like a couple of hours now.

So I cannot say whether that really is the root cause, because I had other moments where I saw the problem disappear temporarily - like I said, 10.0.1 etc. But what may be the case is that some of those routers - especially the new ones with their advertised "beam forming" actually are much more efficient at interfering with your bluetooth devices if you happen to have them just in the wrong place. The fact that I could correct the problem, temporarily, changing the location of the bluetooth device, or also that I removed the problem by reconnecting the device - essentially, switching it off for a moment - may just mean that I reconfigured the Bluetooth device topology, and hence had the problem go away for a bit.

Hopefully, that will help some of you (and hopefully, that's a solution this time).

Cheers,

Hi Cabiman, like I wrote in my other post, maybe that's actually the root cause of all of that. But switching Wifi off on your Macbook would solve the problem only if you are using the 2.4 GHz band (which on a newer Macbook would be a waste anyway). For me, I had Wifi off anyway all the time when the Macbook was connected stationary, so I didn't bother to try it. My issue perhaps was that I have other devices - like an old IPhone 4s, or an old IPad 2 - that are using the 2.4 GHz bands from my router.

And perhaps the problem is really also because it may depend on where really all of those devices are physically located. As I wrote, I can move these things around a bit and see the problem go away.

My take is, I may have a solution here. Just try it out and do disable the 2.4 GHz on your access points. I am a very fast and sensible typer, so I immediately can feel if something is getting in my way with my bluetooth keyboard. It starts off with a very slight delay, and then keeps getting worse. This time, since I did that change, I can clearly feel the problem has gone away immediately - and comes immediately back when I re-enable the 2.4 GHz module on the Access Point.

So that's good because it gives us so many opportunities to shell out some more money for newer Apple devices ;-)

For me, it seems much better on 10.10.1 but I still get drop-out, mostly after sleep I've closed the lid and re-opened it. So far, it seems pretty good on a clean boot.

In my situation, it's nothing to do with WiFi as the BT is rock solid in otherwise identical circumstances in BootCamp, and didn't occur before Yosemite.

Well the one doesn't exclude the other. I may absolutely be that Yosemite has introduced a problem that makes its protocol more vulnerable to these issues than a prior version or another OS. Like you, I've never had that kind of problems ever before.

Actually it seems pretty obvious that it has to do with the wifi at 2.4 Ghz.

At home I'm using my MacBook with a 5 Ghz wifi and have no Problems using my Magic Mouse.

At work I'm using a cable connection but activated the hotspot on my MacBook so I can use it with the iPhone.

The hotspot works with 2,4 Ghz. MacBook and iPhone are just next to the Magic Mouse obviously.

If the hotspot's on, I have problems using my mouse. When I turn the wifi and therefor the hotspot off, the problems are gone immediately.

I updated to 10.10.1 and still having the same problem. That is very frustrating.
