If you are having trouble with your voice chat, here's some things to try.

Microphone Not Working on Mac OS

There are two known causes of this.

  1. Patch 1.63 fails to ask for Mic permissions correctly.

  2. Previous versions of Killer Queen Black had a bug where after an update, OS level permissions to access the microphone got cleared . In this scenario, your mic is working fine in other games and applications, just not Killer Queen Black.

Here's a step by step guide to resolving this issue. Not for the faint of heart! Proceed with caution.

Method 1: Add Permissions to info.plist

  1. In steam right-click on Killer Queen Black -> Manage -> Browse Local Files
  2. Right-click Killer Queen Black app, 'Show Package Contents'
  3. Open Contents Folder
  4. Open file Info.plist in a text editor (this could be tricky if you don't have one, google for "Sublime Text" and try editing using this app)
  5. Paste the following on the line right before </dict></string> and save:
<key>NSMicrophoneUsageDescription</key>
<string>Voice chat</string>

Next time you open Killer Queen Black and attempt to voice chat you should see a pop-up from Mac OS asking for for permission to grant Killer Queen Black microphone access. Make sure to allow!

Method 2: Disable System Integrity Check (Reboot Into Recovery Mode)

  1. Hold down command (apple) + R on boot
  2. Open Terminal app
  3. type
csrutil disable

Reboot back into normal mode.

Perform Terminal Incantations

  1. Open terminal app, and type following three commands
sudo sqlite3 ~/Library/Application\ Support/com.apple.TCC/TCC.db "INSERT or REPLACE INTO access VALUES('kTCCServiceMicrophone','com.Company.ProductName',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1551892126);"
/usr/libexec/PlistBuddy -c "Add NSMicrophoneUsageDescription string" ~/Library/Application\ Support/Steam/SteamApps/common/Killer\ Queen\ Black/Killer\ Queen\ Black.app/Contents/Info.plist
/usr/libexec/PlistBuddy -c "Set :NSMicrophoneUsageDescription Using voice chat" ~/Library/Application\ Support/Steam/SteamApps/common/Killer\ Queen\ Black/Killer\ Queen\ Black.app/Contents/Info.plist

Re-enable System Integrity Check (Reboot Into Recovery Mode)

  1. Hold down command (apple) + R on boot
  2. Open Terminal app
  3. type
csrutil enable

Reboot back into normal OS mode.

You should now be all set!
