It is possible that there is something near your iMac that could be causing interference to the Bluetooth connection, perhaps another Bluetooth device. I also assume that the mouse is only paired with the iMac and no other machine.
However, the first thing you should try, if you haven't done so already, is remove the mouse from the list of Bluetooth devices on your iMac (you may need to rustle up a corded mouse temporarily after severing the connection if you don't have "Open Bluetooth Setup Assistant at startup if no mouse or trackpad is detected" under the Advanced menu). Then re-pair the mouse with the computer. You should also delete any other devices that your iMac doesn't use.
I'm not sure how much of a difference it will make, but under the settings menu, which is just to the right of the add/remove buttons on the Bluetooth menu, you can add the mouse to your favorites list, as well as update service. Doing so shouldn't hurt anything and can only help matters.
Excellent advice.
I will try all of it and report back.
Sad to say that it did not work.
Removed and added fresh to my Bluetooth and the Magic Mouse is still disconnecting.
From the drop down menu, Add to favorites.
Trash the Bluetooth prefs and reset the PRAM.or have you tried the "piece of paper" solution? My Magic Mouse developed this problem about a year into its life and I tried the various suggestions, including cleaning the contacts. What solved the problem for me (said problem has never returned) was cutting one piece of note paper (3.5" x 1.75") and folding it to fit. After folding, I ended up with four thicknesses of paper between the two batteries and two thicknesses of paper between the batteries and the cover.It is in my Favorites already and still drops in and out

I never heard of the Piece of Paper solution.
Are you suggesting that the batteries may be losing contact inside the Mouse?

but it does not interference with the keyboard that i assume that wireless too?
For a while now (few months), my Bluetooth Magic Mouse has been disconnecting and reconnecting from my Imac.
It is running on fresh batteries, so power is not the problem.
Any thoughts why this might be happening and how to fix it?
You kicked up an 2.5 year old threadPossible solution.
I really hope this works for you...

And it works in June 2018. Thank you! This has been driving ME nuts for months!The folded paper works.
