Edit: it won’t work with a VM no matter what. And to be fair, this is a mac forum. I don’t have access so a windows box so what am I supposed to do?

The instruction says that USB-A is required. I have tried to upgrade D6000 by VM (Parallells Desktop), but even all progress bar is complete, I get alert on the end that installation failed. The same result is with the last two firmwares. Even that, It looks like A02 firmware (not the latest one) seems working for me (https://www.dell.com/support/home/uk...sal-dock-d6000).

I also did PRAM reset: https://support.apple.com/en-us/HT204063

Right now, after my computer wakes up, it restarts every time (I've already sent a crash reports to Apple). Other things seems to work!
