Mouse and keyboard keep disconnecting

I recently bought a new MacBook Pro running Mojave and had the same issues. I used an older Magic Mouse and Apple Keyboard that worked fine on my mid-2008 Mac and then connected them to my new computer. I tried new batteries, the paper in the battery compartment and all those other tricks and nothing worked. I finally used <option> + <shift> and clicked on the Bluetooth symbol and did individual factory resets on the mouse and keyboard and then reconnected them to the computer. the connectivity is much better now but still not 100%.

I had an upgrade to 10.14.5 Beta and also removed Android File Transfer.

Whatever did the trick, we have not had issues since then.

This is a hardware failure. The bluetooth module is defective. Apple is aware but they will never admit it. If you want to solve, buy a bluetooth dongle or a logitech mk850 keyboard or mouse combo or similar

This might work while the Apple software mob are working out what is wrong and how to fix it. Instead of letting the Mac go into sleep mode after we have finished doing what we are doing, we select restart instead of sleep. Whether this clears something I don't know but, so far, the disconnects don't seem to be occuring.

We're six days down since installing 10.14.4 and removing the Android File Transfer. I have been putting the Mac to sleep rather than restarting it.

Taking a very, very big breath - I have had no disconnection problems since doing those things. All is solid (at the moment!).

So, at face, it would appear that these things have worked.

Mikefrom ReadingUK - that sounds like a lot of techie stuff - anything simpler?

Proffie - good idea - its definitely the APP for me only - I deleted it twice and then tried an alternative and immediately lost connection to keyboard and mouse so got rid of that one also - since then no problem at all (except I can't get my images off the phone and am spending days trying to research how to do it) SO annoying and time consuming. there is no way in the world I am getting an iPhone (much as I love things Apple).

Profffie - I have multiple external hard drives via USB to my Mac running Mojave 10.14.4 and once the android transfer app was deleted all is good.

Nicksage - I did try that but as soon as I went to use it the failure kicked in immediately,

I do hope something changes in this regard soon. (this and my Benq monitor (AND the scanner as separate issue) not being recognised by Mojave - I see on the Internet that's a 'thing' too and its another time-waster I cannot work out).

(hear me scream....)

I deleted my screensaver, the fireplace, and no mouse problems so far. Do you guys have a screen saver running?

2 days ago, I just reinstalled Mojave 10.14.2 and the problem disappeared. Now 10.14.3 is available and I just installed it. Keep my fingers crossed.

I've just done the same, purchased a wired mouse, out of frustration and desperation. A crappy solution indeed for a problem that Apple should have resolved by now!

Android file transfer was the culprit for me as well.

Yep. I'm in the same boat. Had to get a new iMac as old faithful - 8 years old - stopped displaying and it was replace not repair time. So, with the new one, as others have noted, mouse and keyboard disconnect with annoying frequency. So SMC reset, NVRAM reset, external Seagate drive (for Time Machine) taken off the USB port. Went to Apple store and had machine checked. All hardware showed normal - all green ticks. So we wiped the drive and reinstalled the latest version of all software as the 'genius' deduced it to be a firm/software issue. Because reconnection was occurring and all works okay after that, a hardware issue was ruled out. He said that if the hardware was faulty that (a) it would have shown up on their u-beaut diagnostics and (b) if a part had actually failed it really wouldn't magically fix itself. So home we went and restored from the back-up. Since then, I've been keeping a log of the disconnects and what was running at the time. Suspiciously, when the external hard drive is showing Time Machine activity (that's all it does and is used for), a disconnect is usually there.

So if it persists and can't be fixed, under Australian consumer laws, it is a case of a warranty issue for either replacement/repair or refund. That said, I'd be equally happy to go back to a corded keyboard/mouse as they seem to work consistently. In the case of the 'magic' devices - 'now you see, now you don't' seems to be a common outcome.

In the meantime I am using an 8 year old magic keyboard and a corded Swann mouse. I'll monitor all for at least three-four days and then, if no disconnects show, I'll know where the problem might lie and then bat it back to Apple for them to solve.

Problems persists. Disconnects still occurring. Interestingly, the corded mouse's pointer still works, the mouse clicks don't.

Two lines of thought -

1. Does it seem to happen when Time Machine (in my case through the USB3 to an external Seagate HD) is active? A conflict there?
2. Replacing bluetooth keyboard/mouse with a corded keyboard and mouse - does this eliminate the non-response issue?

If it is the latter, then this will give a strong pointer to where the problem lies.

I'm working with a dedicated Apple Support person to isolate/analyse and hopefully fix the problem.

At the moment I am running the Mac in Safe Mode and there have been no issues. We tried running a test Administrator and that also worked. Things seem to go pear shaped when I sign in under my normal profile and the disconnects start up again.

I'm not a tech, but, this would seem to give clue where the Apple people should be looking for the conflicts that cause the disconnections to occur, i.e. my profile and what that runs in the background compared to running safe mode and what doesn't run in the background.

The support person I am working with has been very helpful and is quite committed to working out what is happening and why. He is a good representative of the organisation.

I do return to my initial non-solution/solution. I am quite happy for Mr&Mrs Apple to call their two errant children (Magic Keyboard and Magic Mouse) home and to send me a corded keyboard and mouse which, I do believe, will stop my problems. I know that it is not an elegant solution, but if it works and stops the annoyance I'll be happy while Apple sorts things out and sends out a patch/update to fix the issue.

Hi

I do not know if this will help but it is worth bearing in mind.

I had a problem where I could not pair mouse or keyboard to 2nd mac.

It was due to another mac in home which these items were originally paired to still having bluetooth turned on, once I turned bluetooth off of 1st mac they would pair to 2nd mac.

Bluetooth will travel through walls and floors it seems.

Same problem here, since Mojave, as described. Mac restart helps always, also sometimes Bluetooth off and then on again. Mouse and keyboard is disconnected. Had I no USB mouse I would be completely lost every time. This way I at least can off/on Bluetooth.

Already with earlier OS I had Bluetooth problems, but different. Paired devices did not connect, had to on/off devices, on/off Mac, whatever, terrible. But this now is worse. I type and realize after whatever time that nothing happens on the screen.

We own the most expensive hardware and it doesn't work!

Apple seems not only to have iPhone sales problems.

Apple, H*E*L*P
