magic mouse and keyboard keep disconnecting from bluetooth

Hi - I also had this problem and "solved it" by deleting the Android File Transfer application. The Apple Support folks were unable to solve this, and the Apple Store gave me a second, brand new iMac within a week of getting the first one. Of course, the problem remained until I discovered this thread :-) (Discussions with Senior Apple Techs included learning that they do not access Community threads. They rely solely on what is listed in their internal information channels.)

Question: Is there an application equivalent to Android File Transfer that can be used without the Bluetooth problem? I need some way to get to my DAP (digital audio player) to add/delete music files. Thanks!!!

I confirm this as well. Soon as I uninstalled Android File Transfer and re-booted, both the bluetooth keyboard and mouse resumed working. Problem only exists on my Mojave iMac, have not had any bluetooth problems on my High Sierra machine with AFT installed (but removing AFT just in case, on that older machine too).

My Bluetooth Apple keyboard was losing connection regularly. Found the culprit. I had an Apple HomePod active on my desk at the same time. Switched it off and the keyboard seems happy. It would be good if Apple could find a way to have multiple bluetooth devices running in close proximity without a device failure.

I can confirm deleting the Android File Transfer app did it for me too. Hadn't had an Android in years and didn't realize it was still on my Mac. Did a Migration from an old to new Mac a few days ago and set my magic mouse and keyboard up and have been having connectivity problems since. I read this thread and said, "pfffft, I deleted that a long time ago." BUT low and behold, there it was. Phew.. Thought I was gonna have to take drastic measures. Thanks to you and everyone who confirmed this fix.

Thanks. This worked for me. Been having the problem since last October. Discovered that was when I'd installed the Android File Transfer app. Removal of that app solved the problem for me.

Greetings sattod,

Thank you for using Apple Support Communities. It seems like you have Bluetooth devices that are intermittently disconnecting. One thing that can cause this to happen is if there is wireless interference. I would recommend you use this article to help troubleshoot the issue.

Potential sources of Wi-Fi and Bluetooth interference

Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.

Take care.

Okay, happened to catch the bit about Android File Transfer and it just so happens that I DID have to download and install that about a month ago. This issue seems to have happened about the same time. So just deleted Android and we'll see what happens! Perhaps I will owe Apple an apology and can blame Microsoft who made the Android FT app! Appears there may be some issue with deleting "all" of the Android File Transfer app per some online chatter; however, could only find the app itself and it seems to have deleted. Also restarted iMac.

Thanks for config issue berabert1 .... hopefully we can close out this discussion!

My configuration is exactly the same as yours bertabert1 except for my memory being 24GB and my energy saver preferences being set to default.

Like I say mine has been perfect since deleting the Android File Transfer app, so I have to thank you for that as this disconnecting constantly was sending me nuts and I would have gone back to High Sierra if I hadn't seen your post. I can see people have the same problem with High Sierra but I never did have a problem with it.

Solved it by doing some of my own troubleshooting. For me, it was creating a network on my macbook through an ethernet cable. I turned it off through System Preferences > Sharing > uncheck "Internet Sharing".

Consider what might be using bluetooth and interfering with your keyboard/mouse, and test turning it off.

SOLVED! Successfully fixed it on my end — all I had to do was disable bluetooth on my phone (iphone in this case) and the disconnection problem stopped. My phone sits next to my wireless keyboard which was probably causing interference.

I confirm, that after deleting Android File Transfer the bluetooth devices work OK!!!

Well, I can say that my mouse and keyboard has not disconnected since removing the Android transfer app...Thanks for the tip.

I too had this problem. It has stopped after I uninstalled the Android File Transport program.

After deleting the android transfer program my mouse now works fine. Thanks for the suggestion.

To bertabert1: Just want to say a big THANK YOU!! I've had the keyboard disconnect problem for several weeks. The disconnects were happening 3 or 4 times a day. Since I trashed the Android File Transfer app. I've had no problems. Although I haven't had an issue in three days I still cross my fingers that the fix is permanent.
