mojave bluetooth issues

I have had 5 calls with Apple support, and have had my calls escalated up at least one level. None of their recommended actions have solved the problem, and the higher level support tech who told me he "owns" my problem has failed to return calls. But I have found a few things that, in combination, have reduced the frequency of problems probably 95%, have stopped (so far) the problem of bluetooth being "not available," and have stopped the need for restarts.

So for what it is worth, I suggest: (1) Buy a basic wired mouse and plug it into a USB port. You get get an Amazon basics mouse for a few bucks. That gives you some usability even when keyboard and wireless mouse get disconnected (2) in System Preferences/Energy Saver put a check mark beside "Prevent computer from sleeping automatically..." I have no idea why this should have any impact, but my most recent support rep told me about a problem like ours that was helped by doing this. This seems to have eliminated almost but not quite all instances of bluetooth problems. (3) When the mouse and/or keyboard get disconnected, I power off the mouse for a few seconds, then power it back on. Most of the time the result is that both bluetooth devices get reconnected within a minute. (4) If that doesn't work I turn bluetooth off. Sometimes the command to do this is not instantly responsive. I have had to wait a minute or a bit more for it to be responsive. But when it does finally work I then turn bluetooth back on and both the mouse and keyboard reconnect immediately.

I hope these steps help. Good luck

I bought a brand new iMac Retina 27" in November and experienced this problem from day one. I must have spent about 10 hours on the phone to Apple support. I even went through the hassle of having the iMac replaced - but it made no difference. I have read online that some people have had various parts replaced (blue tooth module, motherboard etc) without success.

Like the previous poster my call was escalated to a senior technician (on numerous occasions) who would "own" the problem - unfortunately after the escalation it was very difficult to speak to the same person again. Eventually one of the senior technicians supplied me with a diagnostic tool which I used to upload some information (log files, dump of system settings etc.) to Apple. I managed to speak to a different guy a couple of weeks later and he told me that the logs had been analysed and they confirmed it was a known fault with bluetooth and that Apple were working on a solution. This fix should be in the next release of MacOS (Mojave 10.14.3).

I have downloaded and installed Mojave 10.14.3 and hopefully it includes the fix - so far my iMac has been free of Bluetooth disconnects for 2 hours.

My keyboard and mouse kept disconnecting. Apple Care wasn't any help, called them 4 times.

Removing the Android File Transfer app fixed the issue 1 month now.

to all recent post.

try disabling the sleep mode as I indicated on the 17 of December:

it did work for me ever since.

I also removed the Android File Transfer App. and have not had a problem since...about 2 weeks now.

Thank you!!!

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

It has worked for me too, at least 99% Every once in a while I still lose bluetooth, but have found that powering my mouse off an on reconnects almost instantly.

I'm glad it worked for you. I confirm I had no more issue since I disable the auto-off option

Sometimes resetting the SMC can help How to reset the System Management Controller (SMC) on your Mac - Apple Support

Also see the tips here If your Apple wireless mouse, keyboard, or trackpad isn't working as expected - Apple Support Interference from another device is often overlooked.

not sure of this.

Removing the auto off function solved all my problems (I still have not reinstalled Android tool to double check, but I'm confident)

possibly there are several causes and several solutions depending on the individual cases.

Finally, some indication that Apple might recognize and be addressing the issue. My fingers are crossed.

Meanwhile, it sounds like you have had the same experience with a senior technician who "owns" your issue. I am disappointed to hear that someone else has had the same experience with those who have told us they are responsible for helping us resolve issues. At a minimum, I don't think it is unreasonable that these case owners would contact customers with whom they have spoken about what is now a known issue.

Perhaps I spoke a fraction too soon. I experienced a very brief loss of bluetooth (<1 minute) this morning. Not as bad as what I had been experiencing, but makes me nervous

I too have been experiencing the exact same symptoms. I have even updated to 10.14.2 which has not helped.

Bluetooth goes down and I have not figured out how to get it reloaded without a restart.

I am afraid to say that the problem still exists on MacOs Mojave 10.14.3...

The above, stopping BT from going to sleep did the trick for me - Thank you ! Was very frustrating !
