macOS HS 10.13.4 breaks Boot Camp drivers/keyboard

It would appear (and this is purely my own opinion) that there was a change in a Windows update that didn’t cause an issue until High Sierra 10.13.4 was released. Clearly something has then changed there that has bricked the bluetooth connection in Bootcamp.

Seemingly some people have had success removing specific Windows security updates and that’s exactly what I’m planning to do tomorrow when I can get at my machine.

You’re absolutely right though, the point of Apple is that their stuff ‘just works’ and they charge a premium as a result. Breaking fundamental parts of the OS like this, and then acting clueless about it (my support experience so far) is pretty poor.

Bootcamp backup from March, 13, 2018 - 1709 without cumulative update KB4089848.

Restored, tested - mouse doesn't work.

So we again returns to 10.13.4 update as source of headache.

As for now I see that the simplest way is to buy 2-nd mouse and use one for Mac OS and one for Windows.

+ $79 to cost of my MacBook Pro.

Does mouse work fine? What mouse do you use? I've got Magic Mouse 2 broken as well.

Yes, the main issue is that Bootcamp drivers a bit outdated, for near 3 years 😟

Thing is I've done last Windows update like March 26th or 27th and everything worked for three days until 10.13.4.

I've got few update mid-March and then KB4088776 March 27th. It worked before and after for sure, always on 1709. KB4088776 has nothing to do with hardware as far as I understand.

By any chance did you fix it?

Any luck?

Could you please explain in more detail? How to verify and can they be altered in Windows to match?

None 🙄

I’m away for a couple of days so am hoping to try again when I get back. I’ll try deleting the Windows updates and see if that fixes the issue.

Yes, link keys are the same in Mac OS and Windows. BT panel says that mouse connected, but it doesn't work.

So you were running 10.13.4 and Windows 10 1607 and peripherals worked?

Yes, at least Magic Mouse 2

If the drivers work on 1607, then 1709 should not break them. I have seen 1709 create issues with GPUs as well.

Yes, Windows constantly changes. And what we have? Bootcamp drivers has timestamp 1 Oct 2015, they are more than 2 years old. It's time of Windows 10 version 1507, with support end date May 9, 2017

One more experiment - I have old bootcamp backup, with Windows 10 1607 (support end date April 10, 2018) - restored, and... mouse works, automatically.

But don't think it's a good idea to use outdated Windows version. We may expect that Apple will support us too.

We got this failure due to lack of Apple support for Bootcamp.

I take 2 mouses, one paired in Mac OS, another in Windows. Both works, so the only problem is links sync, and this problem can be solved only by Apple.
