Possible bluetooth solution

Thank you so much.

I was going nuts about bluetooth disconnection issues, where my mouse and keyboards were unavailable for seconds to long, long minutes (https://discussions.apple.com/thread/250056569?page=1).

Taking the AFT out of the autostart, and killing the PID did the job for me. I am so lucky that my computer is usable again.

Hi I found this thread because I also was having Bluetooth issues with Mojave 10.4.2 the last few days. I turns out that on this last Friday I installed Android File Transfer to test a friends android phone. Today I found this message and promptly removed Android File Transfer (AFT). A few interesting points about AFT. When I downloaded it from the Android website I noticed the Mac requirements were Mac OS 10.7 which leads me to believe AFT hasn’t been updated recently. Also before I installed AFT I was able to hookup the android phone and see it as a “hard drive” with Commander One ( a Finder replacement). As soon as I installed AFT, Commander One couldn’t see the android phone anymore. So my conclusion is that AFT is not a well behaved program as it appears to take over and interferes with general system operations.

I agree Android File Transfer app appears to be what was causing BlueTooth problems for me.

I was plagued with BlueTooth issues (all devices disconnecting, BT unavailable) on High Sierra which disappeared when I did a fresh install of Mojave (moving AFT). The issues returned after installing AFT again on Mojave. I removed AFT from the Login Items and all is good for over a week.

I have opened a bug report with Apple.

I've also had this issue since updating to Mojave.

I deleted Android file transfer and after a few days of testing, can confirm it's worked for me as well!

Thank you! This issue has been quite frustrating..

5K iMac

Mojave 10.14.1

I've tried removing AFT, shutting down the process, restarting computer and it did not help. It became even worse when I started playing with it. I even found some forums related to Logitech MX that's causing it so I tried removing my Logitech Options to find out if that's the cause. No way, it became even worse. Yesterday the mouse was practically unusable. After latest Mojave update it was happening much more often. My colleague uses Apple mouse and Apple keyboard and he has the same issues so it seems like it's something with Bluetooth and Mojave. We both have completely different Macs, he's got 2015 and I have 2018. Apple should investigate into this. Having both bluetooth devices that control your Mac unusable is absolutely not acceptable.

The problem is easily reproducible for me with AFT running, especially when a device is connect through USB. When I kill AFT app and the AFT helper process (kill -9) that is added to Preferences > Users & Groups > Login Items whenever AFT is launched BT returns. You could also try removing (the will be recreated) Library/Preferences/

com.apple.AppleMultitouchMouse.plist

com.apple.AppleMultitouchTrackpad.plist

com.apple.driver.AppleBluetoothMultitouch.mouse.plist

com.apple.driver.AppleBluetoothMultitouch.trackpad.plist

com.apple.HIToolbox.plist

and restarting.

I have opened cases:

47145277  Android File Transfer app breaks BlueTooth on MacOS with Apple.

and 123216504 Android File Transfer 1.0.11 breaks BlueTooth on MacOS wth Google,

and both cases appear to being work with requests for information made.

Since these cases are focussed on AFT, you should open another case to Apple if AFT is not the cause of your problem. I agree that this bug renders your computer useless. The problem for me started in High Sierra and was even reproduced at the genius bar in safe mode (which should prove it has nothing to do with AFT).

Thanks so much! After a couple of minutes, connection seems to be stable now, comparing with earlier sudden disconnect even when I paused a youtube video for about a few seconds.

I've been searching for a power saving setting for a couple of months but i didn't knew what to look for exactly. Thanks for your help!

This! My bluetooth devices were getting connected/disconnected all the time. I ended up plugging a wired mouse and keyboard in my brand new iMac.

Removing the Android File Transfer app fixed the issue 100%.

This tip needs to be included in all the 'what to do when bluetooth is not working on your Mac' tips that float around on the internet.

Thanks for sharing!

I had no end of Bluetooth issues with my new iMac, running Mojave upgraded from High Sierra ( not a clean install).

I went though all the usual things to resolve it. Somewhere along the way it seemed to be “fixed”, I don’t know why.Worked perfectly for about 2 months,.. then the problem came back worse than ever. Same thing, ..tried all the fixes as before but things just got worse.

I bought a Mac specific wired keyboard and mouse as I had given up on Bluetooth.

Then in one last attempt to resolve this ( never give up attitude ) , I saw a mention of Android file transfer as a possible cause. The same post included eye to helper as another.

Turns out Mojave dosen’t Play well with these,..they worked perfectly for me in High Sierra.

They will try to open at login, which they can’t, being incompatible with Mojave. But system keeps trying, resulting in strange behaviour and issues.

There are hidden files associated with these apps that need to be removed to completely delete them from system.

Search on how to do this, follow the guides and while your at it delete the Bluetooth p.lists before rebooting after removing offending files.

My Mac is now running faster, no issues with Bluetooth nor anything else.

Android File Transfer was most likely the culprit, eyetv helper could of been also, ..but not sure of which.

Since I use neither on this Mac, the removal was no issue.

Problem solved for me.

Terminated android file transfer PID and issue resolved for me.

Hello,

after few test in my case it worked better to disable the automatic stop when screen is off as described in this other thread:

https://discussions.apple.com/thread/8615869?page=1

It's my post of Dec 17, 2018 1:22 PM

See the screenshot there, you have to tick the option that prevent the Mac to stop when the screen is off.

I will test and report.

Looks like it is really the AFT - this is anyway a special feature with OS X - happened before, a perfectly safe program shutting down everything at random...

I have to take this back unfortunately.. My bluetooth just shutdown and keyboard and mouse didn't work until a restart.
