Hi all,

Just wondering if anyone else is having peripheral connectivity issues with the 4K UltraFine and the 16” MBP.

The display itself works fine, but after connecting the MBP, none of the USB or Thunderbolt peripherals plugged into the back of the display are recognised. The only way to get everything to appear as it should is to restart the MBP, whereupon everything works as expected. Kind of annoying having to restart every time, rather than just plug it in and get busy.

It’s not a power supply issue, because it happens whether the MBP is also powered via its own charger or not; and hard disks, MIDI controllers, etc, with their own power supplies also don’t connect without a restart.

I’m assuming it’s an issue with the 16” MBP, but actually, I guess it could just be a Catalina thing.

Can anyone with the same monitor and Mac confirm/deny?
