Bluetooth not working after wake from sleep

Hi,

i had the same issue for month on Mac OS Mojave, after sleep mode, my bluetooth acting weird preventing the magic mous to work and the only solution was to reboot... i tried a lot of thing with the Apple support, the reset of the SMC, bluetooth module, etc...without any success. I finally found what was the root cause on my laptop on one specific forum post: the Android File Transfer app.

Don't know exactly why but the day i removed it, this issue was gone :-)

Hope it could help here.

Thanks for reaching out in Apple Support Communities. I understand you're having trouble with using your Bluetooth accessories with your Mac. I know it's important to be able to depend on your Bluetooth signal; I'd like to help. First, use the steps below to start your Mac in safe mode and test for the behavior you're seeing with your accessories:

Start up in safe mode

To start up in safe mode:

1. Start or restart your Mac, then immediately press and hold the Shift key. The Apple logo appears on your display. If you don't see the Apple logo, learn what to do.
2. Release the Shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.

To leave safe mode, restart your Mac without pressing any keys during startup.

Use safe mode to isolate issues with your Mac

If the issue persists in safe mode, I'd recommend using the steps here to see if there are any potential log-in item conflicts in your primary user account: macOS Sierra: If you think you have incompatible login items

Next, restart your Mac normally and use the steps below to remove and re-pair your accessories, then take some time to test:

Pair your Mac with a Bluetooth device

Bluetooth wireless devices are associated with your computer through a process called pairing. After you pair a device, your Mac automatically connects to it anytime it's in range.

If your Mac came with a wireless keyboard, mouse, or trackpad, they were pre-paired at the factory. Turn on the devices and your Mac should automatically connect to them when your computer starts up.

If you purchased your Apple wireless devices separately, learn how to pair them with your Mac.

After you pair a Bluetooth device with your Mac, you should see it listed in Bluetooth preferences:

Remove a Bluetooth device from your Mac

If you want to remove (unpair) a Bluetooth device from your Mac's device list, follow these steps:

1. Choose Apple menu > System Preferences, then click Bluetooth.
2. Hover the pointer over the device you want to remove, then click the button that appears next to the device's name.

After you remove a Bluetooth device, you'll have to repeat the pairing process if you want to use it again.

Connect to Bluetooth devices after wake or startup

Bluetooth devices are usually available a few moments after your Mac completes its startup process. After waking from sleep, your Mac should find Apple wireless devices right away. Other wireless devices can take up to 5 seconds to be recognized. You might need to click a button on your wireless mouse to wake it up.

Some Bluetooth devices, such as audio headsets, might disconnect to conserve the device's battery power after no audio or data is present for a certain amount of time. When this happens, you might need to push a button on the device to make it active again. Check the documentation that came with your device for more information.

Wake your computer with Bluetooth devices

You can click your paired Bluetooth mouse or press a key on your paired Bluetooth keyboard to wake your Mac. You might need to press the space bar on the keyboard.

If clicking the mouse or pressing a key doesn't wake the computer, you might need to allow wireless devices to wake up your computer:

1. Choose Apple menu > System Preferences, then click Bluetooth.
2. Click Advanced.
3. Select the checkbox next to Allow Bluetooth Devices to wake this computer.
   

Using a Bluetooth mouse, keyboard, or trackpad with your Mac

Let me know what you find and we'll keep working together.

I have the same issue on my iMac (Retina 5K, 27-inch, Late 2015). After upgrading to Mojave the mouse and the keyboard happen to disconnect after wake-up. If I am patient and do not click anything, they reconnect after a few moments. If I however happen to click something in the meantime, they are stuck disconnected and only hard restart works.

I followed the above steps advised by BreeZee_17. Unfortunately the issue is still present.

Please support and find the reason why this is happening after the Mojave upgrade?

I had this problem since I upgraded to Mojave and did the same things. Someone else on this string mentioned Android File Transfer being the culprit. I took Android File Transfer off my system, rebooted, and for 2 days so far the problem has not recurred. It was happening almost every time my system went to sleep, so it seems to be really gone.

i had the same problem with the mouse only (magic mouse 2). it could wake the computer out of sleep, but was not recognized once the computer was back on. after trying so many things listed on these forums, i realized an imac of similar age had "enable power nap" in "energy saver" checked. it's worked ever since.

WOW. I've been having the same issues for over a year. Went to apple store and they couldn't help me. I just deleted the Android File Transfer app and VOILA! MY BLUETOOTH WORKS AGAIN WITH NO PROBLEMS!! I can even unlock my MacBook Pro with my Watch every time. And my mouse connects right away after waking from sleep.

I've had this same issue for months.... and Apple Support pointed me at a long shot... that worked:

The application Android File Transfer was the culprit:

1) Move Android File Transfer from Application to the Trash, and empty the trash.

2) Delete the folder Application Support/Google/Android File Transfer from both ~/Library and /Library

3) Delete Android File Transfer Agent (if it's still there) in System Preferences > Users & Groups > Login Items

Finally:

4) Reboot.

I used to have the bluetooth disconnect after wake from sleep issue two or three times a day for months. Did this - and bang! Hasn't happened in a week!

Yes, it helped. Very many thanks!!

I had the same problem on my iMac running High Sierra. Had to reboot my iMac to recover Bluetooth. Searched a solution for weeks, Apple support didn't know.

Finally a new recent found this thread, I uninstalled Android File Transfer and my trouble with my disconnecting Bluetooth after wake from sleep were definitively gone.

Interesting. When I was talking to tech support, I mentioned that the problem kind of coincided with my purchase of an Oculus Go. I had wanted to load my own stuff on the Oculus, which required the Android File Transfer app. I've removed it, hopefully that will solve the problem. I hope so, I was thinking I'd have to take it to an Apple store for repair. Thank you.

I don't have "Android File Transfer" and I'm facing the issue with my new Mac Pro and Mojave 10.14.4. Incredibly absurd to have that kind of issue with a 4000$ computer... What is Apple's solution? They don't even sell wired keyboard and mouse anymore... Does anyone found any other solution than that Google App deletion?

I have the unresponsive magic mouse problem on wakeup. Have had it for about a year now. Currently on Mojave on MacBook pro. Full reboot has always worked but is just too much pain. I recently found that just putting the computer to sleep and rewaking it works and is much faster than a full reboot. I never had the Android Transfer File app, so that is not it for me. There still is something else out there causing a problem. Very annoying!

I upgraded from 10.12 (was working fine) to 10.14.5 and yes, macpro can't come out of sleep via a bluetooth mouse UNLESS I have a wired mouse also plugged in. Then things work normally. Without the wired mouse on the usb, clicking the mouse does nothing when logged into an account; if not logged into an account and sleeping, it will try to wake, but something prevents this and then it just reboots.

The same issue on MacBook Pro (15 inch, 2016) running MacOS Mojave version 10.14.2. The steps provided by BreeZee_17 do not lead anywhere.

same issue for me

yes, see my comment on "enable power nap" in "energy saver"
