High Sierra Mac not connecting to Windows 10

    Hello I am trying to connect my MacBook to my Windows 10 PC with Windows 10 as the server and it's not connecting. This has worked in the past, but I haven't tried for a few months. I don't know if this is an issue with High Sierra or with a Windows 10 update. I have tried two different Bluetooth adapters on the PC.

    I get the devices to Pair, and the Mac sees the PC as a keyboard, but I cannot get HID to ever connect and I can only get RFCOMM to work sometimes. It seems I get RFCOMM to work with my Broadcom USB adapter and I can't get either to connect with the internal Intel adapter.

    I've tried reinstalling and repairing the driver and am still having issues. This could be a problem with High Sierra beta but I just wanted to mention it.

    I know you are working on Version 2.0 and maybe that will help fix this. Otherwise any advice is welcome, thank you!

    Hello Dan B,

    Long time no see. Hope your everything is going well. :)

    We have almost done the V2 development and keep testing it during waiting for delivery of the EV certificate to be used for code-sign to meet the MS code-sign policy for Windows 10. Good news is we have been verified to get the certificate yesterday and we can release the V2 soon.

    The symptom you're experiencing is exactly the same as I did during testing. The only difference is client device but noticed that the identical problem occurs for all Windows 7/10 PCs and Sierra Mac's as a client device. The symptom I think would be related with a recent update of Windows 10. I have found that many Windows 10 users are experiencing Bluetooth keyboard/mouse problems after applying August update, by googling. I hope MS fix the problem quickly.

    In the mean time, you may be able to workaround the issue by turning Bluetooth Off and then On, in both Server & Client computers, just only once after pairing. Does it really work for you?

    Hi Seungjin,

    I didn't want to reply until I had tested this. I tried again and turned Bluetooth off and back on as you described and was not able to get the HID connection status to show Connected. RFCOMM will show Connected sometimes but it is inconsistent.

    This is just a guess but it seems like Windows 10 is taking control of the Bluetooth HID connection before Across Center is able to. I see a notification appear saying that Windows is configuring the device when I pair the Mac.

    Oh well, I do love Across so hopefully it will be fixed in a future version!

    I was little bit confused. Sorry. There was no problem in Windows 10 as server. The problem that I mentioned occurs when Windows 10 PC works as a client device. Your Windows 10 PC is the Server?

    If you have other devices that can be used as a client device, please try to connect them to your PC. Anyway let me test how my High Sierra Mac works. I need to download and install High Sierra.

    I have tested High Sierra. It is very unstable with every computers combination including Windows 7/10 PCs and other Mac. HID connection succeeds very little often. If it always fail, it deserves to debug, but very little number of successful HID connection mean that High Sierra has problems.

    So I recommend you to roll back or you can help but waiting for next stable version of High Sierra beta. In the mean time, how about using your Mac as the server?

    Hi Dan B,
    If you are still suffering from the issue, I recommend you to use across V2 beta through network instead of Bluetooth, until High Sierra gets stabilized.

    I am experiencing the same issue. It was fine for two days since I updated to 11.13.1 but since today is also disconnecting every 10 seconds. Did you find out how to fix it? Is the V2 beta fixing the tissue?

    Hi poliolet,

    Welcome to Across Center!

    What OS is Across Server and Client respectively?
  9. poliolet

    poliolet New Member

    Across Server is Mac OS High Sierra with latest update (which fixed the issue for two days).
    Across Client is a Windows 10 Pro

    I'm suspecting bluetoothaudiod in High Sierra would have a bug. You can work around the problem by renaming bluetoothaudiod to other:
    1. Reboot your Mac and press "Command+R"-key during booting to enter the recovery mode.
    2. Click "Utilitites" and then "Terminal" from Menubar.
    3. Change the current volume to the High Sierra volume's usr/sbin/: cd /Volumes/HIGH-SIERRA-VOLUME-NAME/usr/sbin (You can find HIGH-SIERRA-VOLUME-NAME by ls /Volumes)
    4. Rename bluetoothaudiod to other: mv bluetoothaudiod bluetoothaudiodx
    5. Reboot your Mac.

    That's it. If you want to restore bluetoothaudiod, repeat the above steps except that you need to change mv bluetoothaudiod bluetoothaudiodx to mv bluetoothaudiodx bluetoothaudiod.
    Hope it helps.

    For your reference, we will update Across soon to fix the problem -- when a High Sierra Mac works as an Across Client, Bluetooth HID connection does not open.

    Thank you! I will try the workaround and will let you know. By the way, I love Across since is the best app that lets me use my two work laptops. Great job! :)

    I was never able to resolve my issue with Windows 10 as the server and High Sierra as client. I know you asked me to test with another device but I just haven't had one around to test with, I am sorry about that.

    This said, the new 2.0 Beta 1 works via Network. It still does not work over Bluetooth, but with network Across is usable again - thank you! The network seems a little laggier than Bluetooth but it is something.

    I still think the issue is that Windows 10 starts to install my MacBook as a device before Across finishes. In the middle of the pairing process Windows 10 shows a prompt saying it is setting up new devices, so I think it is blocking access to Across. That's just a guess though. If I'm the only one with the issue I am happy to use the new network settings.

    Same here.

    From where can I download the new 2.0 Beta 1? I'd like to give it a try. I use both laptops for work and lately it's been a nightmare.

    has anyone tested the new macOS High Sierra 10.13.1 update fixes the issue with bluetooth?
  17. Seungjin Lee

    Seungjin Lee Member

    Hi poliolet, I have tested 10.13.1 Beta (17B46a; the latest beta) and no good news. Sorry.

    1. High Sierra as Server: I had reported the bluetoothaudiod related (possible) bug to Apple.
    UPDATE: It seems like 10.13.2 Beta (17C60c) would fix this bug.
    UPDATE2: No. In 10.13.2 Beta (17C67B), it works worse than 10.13.1.

    2. High Sierra as Client: I have fixed the issue that BT HID connection isn't made. The fix has been done in Across for both macOS and Windows, and therefore it's not easy for our users to patch the fix instantly.

    I'm struggling to fix all major problems in v1.32 and v2.beta1, and the updated version will come soon.
    Thanks in advance for your patience.
