Blank NDI inputs from vMix Desktop Capture for Mac

You may see blank NDI inputs in vMix when using the vMix Desktop Capture for Mac due to Mac Privacy settings, especially when using for the first time. However if you have used the vMix Desktop Capture for Mac app before and recently performed an macOS update, these settings may reset or may need to be re-added again in order for the vMix Desktop Capture for Mac app to start working with vMix again.
 
This setting can be found by doing the following on the Mac computer:
 

Step 1

Make sure the vMix Desktop Capture app is not already open. Then open System Preferences on the Mac.
 
 

Step 2

Open the Security & Privacy option
 
 
 

Step 3

Select the Privacy tab at the top. Then select the Screen Recording option in the left sidebar. From here tick the checkbox next to the vMixDesktopCapture option. Or if it is already ticked, untick it and tick it again. Then close this window.
 
 
 

Step 4

Open the vMix Desktop Capture app for Mac. Then try adding your NDI inputs into vMix.
