Das Keyboard 4 Professional For Mac - How To Update Firmware

Updating Your Das Keyboard 4 Professional Mac's Firmware

Note: When performing these steps, please make sure that your DK4 Mac is the only board plugged into your computer. When updating, do not disconnect your board or any other USB devices. In the event of an update failure, please close the updater, unplug your board, and contact support.

Step 1. Download the the following:

DK4Mac FW app.zip 1.55 MB

This file contains both the firmware updater and the newest firmware.

Step 2. Unzip the download file. You will see three files:

Step 3. Make sure that the Das Keyboard Q Software is disabled if you have it installed. To disable the software, please do the following:

  • Copy and paste the following command into the terminal and hit ENTER. This will stop the Q Software services.
launchctl unload /Library/LaunchAgents/com.daskeyboardq.service.plist

Step 4. Double click the DKFW-HYKBUtility.app to run the program. If you receive a security warning, please refer to the steps at the end of this article to bypass this warning.

Step 5. The software will appear as below. Select the "Model" dropdown and select your board (the dropdown will likely say "Das Keyboard". This is your board)

Step 6. Select "Get Firmware Version" to check your current firmware version. Note this just in case you need to contact support.

Step 7. Finally, select "Firmware Update". This will open your file directory. Navigate to where you unzipped the initial folder from step 2. Within this folder, double click "L2175V16.bin" to select the firmware upgrade. 

Step 8. The upgrader will automatically begin the upgrading process. Please allow your board to sit for 5-10 minutes. 

Step 9. Once complete, you should be fine to use your board as normal, with updated firmware! Make sure to start the Q Software services again if you disabled them in STEP 3. Here's how to start the service again:

  • Copy and paste the following command into the terminal and hit ENTER. This will start the Q Software services.
launchctl load /Library/LaunchAgents/com.daskeyboardq.service.plist
