10.13.4 Broke BootCamp Bluetooth

Greetings!


This is super urgent! I need help! Fresh macOS 10.13.4 update most likely installed some new firmware because now I cannot connect to my keyboard or mouse in Windows 10! I tried re-pairing, reinstalling drivers, rebooting and resetting PRAM. Devices seem paired, but they never connect. They connect and disconnect every second to be precise.


I need Windows 10 working by Monday. Kindly give an advice, please.


Thank you.

Sorry for the duplicate post, it won't allow me to edit or delete the previous one.

It’s taken a while...as it always does.

Right, with MacOS 10.13.3 installed from my Time Machine backup, and having installed Windows 10 Pro without running any updates everything worked fine.

I then ran Windows update and installed the following...


- Definition update for Defender Antivirus (KB2267602)

- 2018-03 Cumulative Update for Windows 10 version 1709 for x64 systems (KB4088776)

- Windows malicious software removal tool x64 - March 2018 (KB890830)

- 2018-03 Security update for Adobe Flash Player (KB4088785)

- Update for Windows 10 Version 1709 for x64-based systems (KB058043)


Having installed these and rebooted, both the keyboard and mouse immediately stopped working.


I then booted back into MacOS and you’ve guessed it, the mouse didn’t work without having to re-pair it.


I found that in Device Manager-Bluetooth, for every device listed, in the events tab there is a message saying “device xxxxxxxxxxxxxxx requires further installation”. It means nothing to me but someone more knowledgable might be able to get something from it.

I’m now reinstalling Windows 10 and will not update it until I know this is fixed. I really only use it for occastional gaming and for browsing mainstream websites related to gaming so I’m willing to risk it.


I might even install MacOS 10.13.4 as I now think it’s not actually this that is the issue, it’s definitely a Windows update problem. Perhaps an update to the Bootcamp drivers is in the offing but for now, it’s most definitely broken. If I try it and it works I'll let you know.


Cheers

The other workaround - far from ideal - is to connect the MT2 by the lightning cable when booting into Windows.

Another thing I've noticed is that the screw up with the MT2 can also affect my Magic Keyboard. Sometimes I can't login as the keyboard doesn't work, but if I make sure the MT2 is switched off when booting into Windows, then I never have an issue with the keyboard as a BT device.

Hey again,


Just to let you know that in the interests of trying to get to the bottom of this, I went ahead and updated macOS to 10.13.4.


Well....it works! Both the MM2 and the MK are working fine in that same bootcamp installation, without having installed the previously mentioned Windows updates.


The only conclusion, therefore, is that it's something Microsoft have done. There is a new update to Windows due very soon (Spring something-or-other) so hopefully that will fix whatever the issue is.


Hope you all manage to get it sorted.


Cheers.

Okay. So clean install with KB4093112 does change situation but doesn't fix problem entirely. I have keyboard working rock-solid stable but mouse fails to connect, but not always. Rather once in a few reboots. After that I need either to re-pair in in macOS or turn it off and then back on again to work. Obviously I tried pairing again, power settings etc.


I didn't try multiple reboots on 1803 though. So it seems that to really test we stuck waiting for Spring Creators Update which was amazingly delayed yesterday. For a few weeks apparently.

I can't seem to get an auto-update to 1803 build. I think it might be because im on windows 10 education that isn't activated or something and I don't care to do a fresh windows 10 home install.


I can get KB / M working in both OS, but I have to unpair before switching, then re-pair in OS. otherwise they won't work in Windows at all. I guess I'll just wait it out like this until I see an update go through on the windows side.

Now this is weird. I have very similar configuration. 2017 iMac 4.2Ghz i7, Radeon 575, 32Gb RAM. I am sure they have same radios.


I just installed 1709 from scratch again. Before updates, everything stable. After updates, mouse constantly falls off after reboot. tried resetting everything and re-pairing stuff.


Can you troubleshoot for me please? Kindly unpair wireless mouse and keyboard from Windows 10. Boot into macOS, pair everything that is missing and set startup volume to Windows. Reboot back to Windows. Devices should pair with Windows 10 automatically as it's intended. Then reboot Windows few times, 5-7. For me occasionally mouse will die once in a few reboots. Will moise connect every time for you?
