Magic Mouse laggy. Could it be a Bluetooth problem?

Hi there,

Every now and then my Magic Mouse seems to glitch a little. And sometimes it glitches a lot, and for a while. My Mac Pro is underneath my desk in a compartment that is made for a desktop computer. Could it be that the bluetooth signal sometimes isn't at its best?

I'm thinking about buying a USB Bluetooth dongle that I can put on the front of the Mac Pro's USB port and see if that fixes the problem. Does anyone have any recommendations for a USB Bluetooth dongle?

Mac Pro 3.2GHz Quad-Core Intel Xeon "Nehalem" (Mid 2010), Mac OS X (10.6.7), 12GB 1066MHz DDR3 SDRAM

It might be a bluetooth issue. If you search the forum posts here you'll find threads about the issue.

One of the links referenced in the threads is:

Personally I used the pigtail/antenna solution. It works like a charme and is an easy fix which does not break sleep/wakeup (as some USB dongles do).

Hi and thanks for your post. I remember reading this blog a little while ago as I've been experiencing this behaviour with my Magic Mouse for some time now. I was skeptical at first to give it a go but reading it once more has made me realise that it's not that difficult. Just a lot of steps I guess. I'll let you know how I go. Thanks again 🙂

I've been looking around on eBay and I'm not quite sure which antenna I need. There's different types like 9dBi, 12dBi and 19dBi. Which type is best? Is this one any good?

Hi lMolto
I have had A look at your link for an antenna.
First you need to understand that the bigger the Db number the more powerful the signal will be but also the bigger the antenna will be.
For general use a 7Db should be fine.

Hi nobbly,

Firstly I want to say thanks for your blog. I'm so sick of my Magic Mouse problems and I can't wait for it to go away. I've found another antenna which is 10 dBi. I'm happy with the price and size so I will probably get that. As for the cable, I'm having trouble finding one that is 12 inches. All of them are 7 inches. I've contacted one of the sellers on eBay if they have a 12 inch one. I'll let you know how it goes. Thanks again 🙂

After all this time, I still haven't been able to find a 12" cable. So I have given up and decided to use my Mac with the side cover left off. It does help quite a bit. My mouse feels a lot smoother and less laggy. I should have done this a long time ago. I have some concerns with it though.

Can leaving the cover off of my Mac Pro cause any problems? Such as cooling problems or anything?
