    I got my 27" iMac in January 2012 and after only 2 weeks, my bluetooth mouse that came with the unit lost connection and after a few seconds it would get that Connection message and as the hours and days went by, it got more frequent...

     

    So, just from experience with Microsoft wireless mouses, I decided to change out the two AA batteries and it solved the problem...well for a few weeks anyway...then the problem started up agan...changed the batteries again and got a few more weeks of use without Connection Lost msg showing up...

     

    Anyway, to make a long story short...I found that the batteries that I was using, "RAYOVAC Alkaline", although they were purchased in January 2012 in one of those multiple packs with like 30-40 batteries in it and are cheaper than other name brands and have a DEC 2018 expiration date on them, seem to be the problem...

     

    I put in a set of "Homelife" el-cheapo brand sold at my local supermarket and they worked fine for the last 2 months or so...

     

    It is not the brand of the batteries but probably the time that the batteries were on the shelf and the location where they were stored prior to purchase...like in a hot place or something...

     

    Yeah...we have put humans on the moon and advanced so far in many, many technologies but for the most part, batteries isn't one of them...once they can tackle that problem...electric vehicles and iMac Bluetooth mouses will finally be 21st century...lol...

    I've had this issue too and after reading all the BlueTooth stuff online I decided to turn off the BlueTooth function on my iPhone while at home to see if it resolved the conflict. So far so good, I have have no iMac mouse outages today.

     

    I had a simiar issue a month or so ago with the wireless modem dropping out due to conflict with my cordless (landline) phone radio signal. That was resolved by changing the channel on the modem. Again, so far so good.

     

    Hope this helps.

    These responses ar all very interesting (especially the RF-related reports), but when my bluetooth goes south, it takes everything down: mouse, trackpad, keyboard and hangs up the printer ("printer connection lost").  This causes a lot of damaged photo paper if a print is even partially started, and if I haven't saved something, that's lost too!

     

    So what can affect the iMac's Bluetooth function? I doubt that it is a frequency issue or it might only affect one of the three devices (do they operate on different frequencies, or just different ID codes)?  Is there a known risk that interrupts the iMac's bluetooth's processing?

    Personally, as I may have mentioned before, I don't have many serious connectivity issues with my trackpad or keyboard. Well, sometimes the keyboard seems to not work for a few seconds, but I don't get the "Connection Lost" sign on the computer.

     

    My money is on this being a MMouse issue. After both the low-tech and high-tech fixes, the mouse seems to be working for longer stretches without connectivity issues, but it still goes out from time to time.

    Hmm, my Bluetooth idea worked for a day and then didn't, so that must have been a coincidence. The guy at the store suggested using different batteries so I am now using Energizer AA Alkaline batteries, which he recommended (and they were on special) and again so far so good.

    Yeah, same thing here...after I put in some newly purchased batteries in my iMac Bluetooth Mouse and it is good now with no disconnect issues...

     

    Along the same lines, I also noticed that the iMac Bluetooth Keyboard, uses a lot of current on the batteries and it also has issues with batteries that may have been on the shelf longer than desireable...

     

    I hooked up a New USB wired iMac Keyboard that I had lying around, in place of the wireless one and so I don't have anymore keyboard issues...

     

    I am not saying that some people are not experiencing Bluetooth problems but I would check the batteries first...the iMac Bluetooth Mouse is no different from lets say a Microsoft Wireless Mouse, which also dies after a few months and needs a set of fresh batteries...

     

    I guess the keep-alive current drain is higher than one would desire...

    I didn't read this whole thread but I was suprised when I ended up stumbling across my own solution so thought I would share it:

     

    I had the same thing happen as many people here:  Magic mouse was working fine, until I changed batteries. Same thing happend with other staff in the office as they changed their batteries.

     

    And here is what I found!!:

     

    The new batteries we had bought where Eveready and where 1-2mm shorter than the old batteries which where Energizers. The new shorter batteries where not pushing up into the contacts at the top enough to make a good contact.

     

    We purchased new Energizers (1-2mm longer), and all the Magic Mice started working again!!!

     

    Note: Aldi batteries are also the correct size and work fine.

     

    Hope it works for you!

     

    Cheers.

    I never thought about that but I can see where that would definitely coincide with the issues that I was having...in that...the mouse would work fine but it would constantly lose connection and the frequency seemed to depend on how much I moved the mouse...

     

    Looking at this from a manufacturer's prospective, it would make even more sense...

     

    Think about it...if you skimmed off 1-2mm on each and every battery you made and you were manufacturing 50 million a month...that's a lot of savings...and the thinking on the part of the manufacturer's bean counters would be that, hey...who cares since MOST devices have those relatively long conventional coil springs to push the batteries towards the positive post anyway, so the end-users won't have any problems...

     

    Then along comes Apple with newer battery compartment technology...

     

    Great find apapworth77 and thanks for the post...

    This may apply to very few people, but I have had the magic mouse and trackpad problem losing connectivity.  This time it was batteries low; change batteries, turn back on and had not only lost MM but also magic trackpad; couldn't get either back.  Searched forum; reset PRAM, etc. to no avail.  HERE IS WHAT I DID.  Okay, maybe I should have done this before.  I moved my little tiny bluetooth received from the back of my Mac Pro to a USB port on my desktop.  Instantly had both devices back.  Instantly.

    So the whole scraping of the battery terminals worked for me. And I didn't have isopropyl alcohol, so I used vodka. Probably not the wisest; but kitchen macgyver was all I could conjure up.

     

    (I also just use an ordinary knife rather than a scalpel).

    Hello Barry

     

    i have had my imac for about 1-3 months now.... its only been just starting BUT everytime i may slightly bring up my mouse maybe 10mm/1cm and tap it down it freezes and it says "connection lost" then i hav to wait for mby 15 sec for it to come back.... this never used to happen and i would really like it to stop happening currrently i hav around 50% battery so i dont see why the power would do anything

    Josh,

    I kind of agree with you on the 50% battery "power" but that is the "Voltage" and not necessarily under load where the "Current" comes into play...

     

    I mean seriously, how much current can a tiny little mouse draw right???...that's something I don't understand either but by putting in a set of fresh batteries, it seems to fix the lost connection problem, at least in my case it did...on several occasions...

     

    Try it next time it happens and see if it fixes it...

     

    It is an annoying problem nevertheless...
