Doesn't work with OWC Thunderbolt 3 dock
Hi All, I had the vKVM working beautifully between my 2011 iMac and 2015 MacBook Pro via Thunderbolt 2
Then I decided to add the OWC Thunderbolt 3 dock to the mix (Why 3, because I will be upgrading soon and didn't want to buy a legacy dock). So now my setup is 2015 MBP <-> T2 Cable <-> T2 to T3 Adapter <-> OWC T3 Dock <-> T3 to T2 Adapter <-> T2 Cable <-> 2011 iMac
I can manually turn on TDM from iMac, and then use screen sharing to get K+M working, but when I connect or disconnect Thunderbolt from my MBP nothing happens. Looks like the client/server communication is totally blocked by the dock.
Is this expected behaviour or a bug? Any chance this will get fixed? I shelled out quite a bit of cash for that dock, and may need to return it if this doesn't work
I am running latest 1.2.3 Thx
BQ
An update on above, I got it to work by power cycling the dock.
So Virtual KVM works fine, except it doesn't detect Thunderbolt cable plug/unplug, but power cycling the dock works great. I just added a power bar that's easily accessible, and it actually works very nice in my setup.
I think another solution could be to have a manual toggle in the UI, which I believe other people are asking for.
Not sure if it's possible to update the software to detect cable detach when a dock is present, but if it is I think it would still be useful to have that.
Until then for those that have this issue, you can get around it with power cycling.
@BillyQuan can you open terminal and enter this command: system_profiler SPThunderboltDataType
and send the output?

@BillyQuan sorry just a couple more commands:
system_profiler -xml SPHardwareDataType
system_profiler -xml SPDisplaysDataType
My bad ;-)
@BillyQuan it seems like you removed the some of the output.
Should look like this:

Ok, I think I figured this out, good luck, let me know if you need anything else.
@BillyQuan can you run this command on your iMac with everything connected? system_profiler -xml SPDisplaysDataType SPThunderboltDataType
system_profiler -xml SPDisplayDataType SPThunderboltDataType

Hi, sorry for the delay, got busy with work, let me know if you need anything else
No problem. Was the dock connected to your iMac when you ran that command?
@BillyQuan Thanks. I wasn't able to replicate the issue with the provided XML. Maybe I will simply have to give the option for the user to disconnect and reconnect manually from the MacBook.
Just came here to mention a similar thing. I'm running a MBP 2017 with an 2014 iMac. I recently got a Kensington Dock and when I connect/disconnect my MBP from the dock, VirtualKVM doesn't trigger target display mode on the iMac (which is connected to another port on the dock. Obviously the dock is another variable here, and so I'm not sure what it would take to make it detect.
What i've been doing is; connect MBP to dock, then disconnect thunderbolt cable from imac and plug it right back in. Then Virtual KVM will trigger just fine.
Hope that helps.
Having a similar situation. I have a MacBook Pro 2017 connect to an OWC dock and a late 2012 iMac that I'd like to use in Target Display mode. I'm connecting the iMac to another TB port on the MacBook instead of the dock.
When I connect to the MacBook, vKVM disables bluetooth on the iMac but doesn't put the iMac in Target Display mode. It clearly is recognizing the connection because bluetooth is disabled. vKVM is set to AutoToggle both Bluetooth and the Display.
Please drop me a line if you have any suggestions - be happy to help you debug this.
Thanks
I have an Elgato Thunderbolt 3 dock and I am having the same issue. I tried the latest version(1.2.4) and it doesn't change anything.
@flegallo Can you please repeat the steps you did above then go to advanced > Save Debug logs on both the iMac and MacBook. Then attached them to your comment here on GitHub
