Magic Mouse bluetooth mouse keeps disconnecting

Hi Proggie,

I had this issue on Magic Mouse 1 on Mac Mini 2013 model. This was due to the bluetooth shielding on these devices. OWC sent me a little foil looking sticker to place over it. This was causing poor reception.

Even without that particular issues, this can can happen when batteries are low, batteries are alkaline, or there is many devices around on the 2.4 ghz spectrum.

What troubleshooting have you done as far as system software? Have you reapplied the latest 10.11.x combo? (sometimes I find it fixes many of the 'gremlin' issues)

Regards,

Jorge

This happens to me too, all the time and it is driving me nuts. My Magic Mouse is only 3 days old and is 100% charged. After reading some of the comments on this site, i have tried turning it on and off a few times in quick succession and suddenly it started working again. Prior to doing this, Mouse in Preferences kept telling me that it was connected but it would not move. I will see how long it goes on working.

You might want to start your own post since this one is from last year. A new post would be much more visible. You can link to this one.

If your Wi-Fi is capable of generating a 5 GHz signal, try that.

Restart the computer holding down the command - option/alt - P - R keys before the gray screen appears. Continue to hold until you hear the startup chime for the second time.

Reset NVRAM/PRAM

Try moving your modem away - about 2 feet upwards worked for me. Hope this helps.

I fixed it by simply cuting the cover off the positive + end of the rechargeable batteries I use and it hasn't disconnected yet.

Inserting a piece of paper between the two batteries worked for me and my mouse connection doesn't drop at all.

I was going crazy over this issue today. After dismissing as likely culprits loose batteries, bad preference files, or OS upgrades, I tried turning off bluetooth on my iPhone, which is in my pocket near the computer. Viola! Whereas before my Magic Mouse was losing its connection every 2 or 3 minutes, since turning off bluetooth on the iPhone, it has kept its connection more than an hour so far. Fingers crossed...
