USB-C Dock (mDP): June 2020 Compatibility Update

Created on: June 24, 2020
Last updated: April 19, 2022

OWC recently updated the firmware for the USB-C Dock with mini DisplayPort (models OWCTCDK10PMHxxand OWCTCDK10PMDxx), to improve compatibility with the following Mac host models:

  • MacPro7,1
  • Macmini8,1
  • iMac18,x
  • iMac19,x
  • iMacPro1,1
  • MacBook8,1

Any dock purchased from MacSales.com starting 6-15-20 shipped with the update pre-installed. If you purchased earlier from MacSales or from another retailer, you can update your dock to benefit from this improvement but it will require a Windows 10 PC with a Type-A port (using a Type-A to Type-C cable, not included) or Type-C port (using the included Type-C cable). If your product has not been updated and you do not have a PC to apply the update yourself, OWC is providing a program at minimal cost to help you update the USB-C Dock. Please contact our support team for more information.

If you have a PC and would like to run this update please use the following steps:

  1. Download the OWCTCDK10P_2020-06-12_v115.zip file, found here.

  2. Open the zip file. This should generate a folder called OWCTCDK10P_2020-06-12_v115 or very similar.

  3. Connect the USB-C Dock to the host computer using the dedicated USB-C host port (has a computer icon above it).

  4. Open the folder generated in Step 2 then launch the application inside, called OWCTCDK10P_Updater_v115.

  5. You should see a screen like the one below. Note that the device firmware version is different than the 'file version' we're updating to (V115).


  6. Click the 'RunIsp' button (blue and green arrow icon near the top of the window).

  7. The process runs in 3 phases and takes a total of about 3 minutes. Below you can see one of the intermediate phases. If the process gets stuck in the middle for more than a couple minutes you may need to Exit the application, power cycle the dock and then try again.


  8. When the process is complete you should see two full, green bars like the ones below.


  9. When ready you can click the 'Exit' button (blue door icon) to close the updater and begin using your dock with your Mac.
