How to Fix: Apple Magic Mouse Keeps Disconnecting

Apple’s Magic Mouse is a wonderful device. Going wireless can give you the freedom to move about your desk or wherever you feel comfortable. No cord to tie you down. But many who have used the device have reported issues with it randomly disconnecting from their Mac.

While Apple does produce quality devices, it seems that in both versions (Magic Mouse and Magic Mouse 2) of this one, there’s been a steady flow of issues. The good news is that for the most part, this disconnect problem has some simple solutions that will work for most users.

My name is Eric and I am a software engineer but I have a degree in electrical engineering. Solving problems like this can be a real challenge but it is something I enjoy because I get to troubleshoot a problem that could be a hardware or software issue. 

If you’re seeing this same problem, just follow along, and hopefully, I can help you to figure out and fix your Magic Mouse problem.

Magic Mouse Problems

Problems with Apple’s Magic Mouse can really be broken down into 3 categories. They are battery problems, Bluetooth problems, and hardware failure. The majority of the issues fall into the first two categories. Will take a look at each of them below.

Battery Problems

For the original Magic Mouse, the first thing you will want to do is ensure that your batteries are still good. If you have some spare ones, try using them and see if you still have issues. If that does not solve the problem, it could be a common problem that many other users have seen.

This has been an ongoing problem since it first came out and if you have an original one, not the Magic Mouse 2, there’s a pretty good chance that it has to do with the AA batteries not fitting snugly into the battery holder.

The symptoms that indicate this problem are that the mouse may disconnect intermittently after a sudden movement or jolt to the device. A quick solution to this is to remove the battery cover, take the batteries out and then put them back in, but the problem will often arise again.

There are many articles out there that will advise wrapping aluminum foil around the negative end of the battery to make it fit more snugly against the contacts in the battery compartment. I would advise against this solution because it has the possibility of overheating your mouse.

Aluminum foil has a higher resistance than the nickel-plated contacts of the battery and mouse. This slightly higher resistance can cause them to heat up and even be a possible fire risk. While it is unlikely that it will catch fire, the overheating can cause long-term damage to the device.

A common solution is to wedge a small piece of paper or thin cardboard into the battery compartment to keep them from moving around. 

You could also wrap electrical or duct tape around the body of the battery ( do not cover the end contacts ) to make them fit snugly in the battery compartment. The main idea is to keep them from moving around inside the case.

AA battery wrapped in tape.

One more solution is to take the batteries out, and gently stretch the springs inside the case towards the center of the battery compartment. You will need to put a little pressure on them to do this but be very careful to not use so much force that you break them off.

If you are seeing similar intermittent problems with the Magic Mouse 2, it is unlikely to be a loose battery issue since this one has built-in rechargeable lithium batteries that have much less of a chance to be jarred loose, but you will want to ensure that they are properly charged.

Bluetooth Problems

The next most common problem with either version of the mouse is that there is an issue with your Bluetooth connection. There are primarily two types of Bluetooth problems you could be facing. One can be caused by a glitch in the software and another could be due to interference.


If the problem is intermittent, like the battery problems described above, it is most likely an interference problem. There are a number of things that can interfere with Bluetooth. Look for things such as other devices or appliances that could be interfering.

If you can’t see anything obvious, move your computer to another location and check to see if you are still having the issue. If not, then you can be pretty sure that there is something in the original location that is interfering with the signal.

Although most interfering devices come from things unrelated to your Mac, there is a possibility that your wifi connection or some other wireless device such as a keyboard could be interfering. Try turning these off and see if you still have issues with the mouse.

If this resolves the problem, you might want to disconnect the mouse, and then connect it again before you turn on the other wireless devices and your wifi. This may reduce the possibility of the devices interfering with each other.

One last thing to look out for, and this may sound crazy, but be sure that your mouse is not connecting to another computer. Do you have a second Mac close by that it may be connecting to? If so, remove the Bluetooth connection to the other computer and you may solve the issue.

Software Glitch or Stale Connection

It could be that your Bluetooth has been mistakenly disconnected or disconnected by a software glitch. Try the things below to see if one of them resolves your problem. 

Step 1: Make sure that your Mac has the latest macOS updates. If you are behind in the updates, install the latest before you go any further.

Step 2: Go into your Bluetooth connections and ensure that the mouse is still on the list. If it is and it is not connected, try connecting it and see what happens.

Step 3: Try turning the mouse’s power off and letting it disconnect. Wait a few seconds and then reconnect. This will often solve the problem if there is a stale connection.

Step 4: Turn your Mac’s Bluetooth off and then on again. To do this, go to System Preferences and select Bluetooth. Click where it says Turn Bluetooth Off to turn it off. Wait for a few seconds then click Turn Bluetooth On to turn it back on.

Step 5: Unpair the mouse by clicking on x next to it in the Devices list. Once it is has been unpaired, pair it again using the same method you originally used to connect it.

Note: Most of the items above are steps suggested by Apple Support.

Hardware Failure

If none of the solutions above have helped, it could be that you have a hardware failure. Check to see if your warranty is still in effect. If it is, you may be able to get the device fixed or even replaced. 

If your warranty has expired you may need to purchase a new mouse, but before you do that you will want to verify that the issue is definitely with your mouse. If possible borrow one from a friend or family member and try connecting it to your Mac to see if you still have problems.

If you have no problems with the borrowed mouse, then you most likely have a bad one and will need to replace it.

Another method would be to try connecting your mouse to a different Mac. If you still see the same issue on another computer, this will also tell you that the Mouse is defective or has been damaged and needs to be replaced.

Final Words

There are multiple things that can cause your Magic Mouse to disconnect. The most common issues are battery or Bluetooth problems. I hope the information provided above can help you to determine and fix your mouse problem.

Please let me know if you have any other causes or solutions for this particular problem. I would love to hear from you!

    I have a Microsoft Arc Mouse that I connect to my MacBook Pro v13.5.2

    When I first connect the mouse it works great. If at anytime, the macbook goes to sleep, is rebooted, etc, the mouse will no longer connect and I have to delete and re-add it. I can simulate this by simply turning off bluetooth on the mac, and reenabling it. Now the mouse no longer works without removing and re-adding the mouse.

    • Eric

      Hi Dean,
      I’m sorry to hear you are having this problem. I am not really familiar with the Microsoft Arc Mouse but this sounds like a very frustrating problem. I would assume that you have already checked the batteries or made sure that the mouse is holding a good charge. Also do you have any other computers that are within range that they might be connecting to the mouse when your MacBook goes to sleep? You will also want to make sure the mouse’s driver is up to date and that your macOS is up to date. The only other thing I can think of is if the mouse has the ability to update its firmware, make sure that is up to date as well. I hope that you are able to solve the problem and get the mouse to stay connected.


    hi, my magic mouse 3 is keep disconnecting , ive tried plenty of thing to fix it but its still show connected and then mouse off, i am in the middle of my project its really frustrating. i baught this IMAC M1 last year in april 2022 and with in 1 year its been showing problem like this not cool, does anyone have any sol. to this .HELP

    • Eric

      Hi Sumit,
      This sounds very frustrating and I understand your concerns. This type of problem can be difficult to figure out but one of the first things you may want to do is determine if the problem is with the mouse or your iMac’s Bluetooth card. Are you seeing any disconnect issues with any other Bluetooth devices? If you don’t have any others connected, try connecting some Bluetooth headphones, a different mouse, or some other Bluetooth device. If that works without a problem, you will know that the problem is with the mouse. You could also try connecting the mouse to another computer if you have one available and see if the problem shows up on the other computer. If so, this will also indicate that the mouse is bad. If the mouse is bad it may be easiest to just replace the mouse.

    I had to replace the Wifi/Bluetooth in my macbook air as several mouses wouldn’t work. After that mouse works beautifully.

    • Ralph Hoglund

      I had to replace the Wifi/Bluetooth CARD it was. 😉

      • Eric

        Hi Ralph, I’m sorry to hear that you had to have the Wifi/Bluetooth replaced. That must have been very frustrating but I am glad that it is working well for you now.

  • Mats Eriksson

    Well. My original Bluetooth Apple mouse and keyboards do keep disconnecting still. I have tried all resets available, both bluetooth and re- pairing and re-started safe mode, and all extra keys pressing when restaring my macbook pro with osx catalaina 10.15. Mind you the mouse has no batteries but is chargeable via usb. The keyboard has batteries. NOW IMPORTANT: it has worked flawlessly a year back. It is recent thing.

    I have not any more Bluetooth devices, not even the television set, or remote controllers. Now, when I move my MacBook Pro, plus these 2 bluetooth devices TO ANOTHER ROOM, it sails smoothly for a all day, like 8-12 hours without EVER disconnecting. Same distance kept from mouse/kbd to MacBook. But as fast as I move it to my living room which is my main use of this thing since I can connect it to the large screen that is the flat OLED TV and operate things from the couch, it starts to disconnect and re-connect every 5-10 seconds. No cell phones in the vincinity and no WiFi hubs. BTW the wifi is set at 5ghz anyways. But as I detect briefly that someone elses device (neigbors) trying to briefly connect (several different ones) it KNOCKS my mouse and keyboard out from the bluetooth connection. I bet my neighbors having the same problems. I live in a flat so I don’t know who’s gear it is that wants to connect to mine.

    Is there a possibility to stop this Bluetooth on my mac for searching for anything else once I have limited all this to just MY mouse and MY keyboard only?

    • Eric

      Hi Mats,
      I’m very sorry to hear you are having this issue. It sounds very frustrating and it is very possible that those other devices that are trying to connect are the culprit of your problem. I don’t know of a way to keep all other Bluetooth devices from connecting but there is a way that you can keep a particular device from connecting. Once the neighbor’s devices have tried to connect, they should remain in your Bluetooth list. If so you can get those devices’ MAC addresses and tell your Mac to ignore those particular devices. To do this you can try the following steps.

      1. Hold down the Option key and click on the Bluetooth symbol at the top of your screen. There you will see a list of devices that are trying to connect.
      2. Find the ones that you think are your neighbors and look for the MAC address. It will be a long number with a dash – in between every 2 numbers or letters.
      3. Copy that number.
      4. start up Mac terminal – Check here if you are not familiar with how to open Mac Terminal.
      5. Run the following command with the MAC address you copied in place of below.
      sudo defaults write /Library/Preferences/ IgnoredDevices -array-add ”

      This will block that particular device from trying to connect to your Mac. If there are multiple devices, you will need to do this with each one. Just make sure you don’t do it with your Mouse or Keyboard’s MAC Address or you will not be able to connect them. If you make a mistake and add one of your devices to the ignore list, you can reset all Bluetooth settings to get rid of the ignored devices. Good luck, I hope that this can help with your problem.

    Hi. I have this problem with two different mice on two different macbooks. I have the latest MacOS. I’ll try out the battery hacks you give. It would be weird if the issue was an interfering keyboard issues (which I have) since ALL three products are made by apple! Thanks

    • Eric

      Hi Kurt, You are correct, interference from your Mac keyboard is probably unlikely, but since it is a remote possibility, I like to mention it just in case. Most interference problems come from other things such as appliances or other wireless devices but it can be nice to be able to rule these things out when troubleshooting. The majority of the issues that I have seen with the Magic Mouse are battery issues. The battery compartment on these just was not designed to hold the batteries in place real tight and since we tend to move the mouse around a lot, there is a tendency for them to lose their connection. I hope that one of the solutions works for you.

  • Emily Lord

    This is so frustrating but thanks for your help! Updating my Mac OS completely fixed the issue on my desktop… for only about a week. Now my mouse keeps disconnecting again. I tried turning my bluetooth on and off on the Mac desktop and the factory reset for the mouse found in the comments but it’s still disconnecting. Now I’m trying it out using my MacBook and so far it hasn’t disconnected. Wouldn’t that mean it’s not the mouse itself? Agh!

    • Eric

      Hi Emily, this sounds very frustrating and I am sorry that you are having this problem. I think you are correct. Since the mouse seems to work fine on your MacBook, it seems the problem is not with your mouse but with the original computer. It could be that the Bluetooth on that computer is having issues. It’s possible that it could be a software driver problem or it could be a hardware failure such as the Bluetooth card. Do you have any other Bluetooth devices connected to it? If so, are they having issues? If you don’t have any other devices connected to it, you might try connecting one to see if it has issues also and this will tell you that the problem is definitely with the computer and not your mouse.

  • Mike Jones

    Thank you for a really comprehensive answer.

    I’m doing software testing – which is hard enough without frequent disconnections. I have an old magic mouse and the disconnects seem to be getting more frequent – but I’ll certainly try to make sure the other causes are checked out – or heaven forbid… connect a USB mouse !!! or cave in and buy a new Magic Mouse…

    • Eric

      Hi Mike,

      I hope that one of the suggestions is able to help you. Falling back on the USB mouse is a great temporary solution. I still use my USB mouse quite often, especially when I plug it into my docking station.

  • Vía Ventana

    If the mouse disconnects, you can’t go to settings or do any of the fixes. Because the mouse is not connected…

  • TY1ON2K

    Hold [option]+[shift] while selecting the bluetooth menu from the drop-down in the toolbar. This gives you additional options to debug, reset item to factory defaults, etc. Resetting Magic Mouse 2 to factory defaults will fix the intermittent dropping issue.

    • Eric

      Great suggestion! Thank you for your input. I love learning new tips like this.

  • Jack

    Thank you so much. My magic mouse had the battery compartment issue and we had given up on it till i read this. Saved me the price of a new one. Thank you! I just stuck some full adhesive PostIt note in there between the door and the batteries and problem solved!

    • Eric

      Hi Jack,

      I’m very glad that this tip could help you. I have seen it work a couple of times and it is much better (and safer) than using the foil trick that I have seen many others suggest.

  • Tudor

    I’m thinking it might be a faulty mouse?

    • Eric

      Yes, unfortunately, we do see hardware failures sometimes. That can be very frustrating.
