How to fix steam microphone permission macOS

Step 1: Disable The System Integrity

• Disable The System Integrity for access the relevant system database.

Reboot your Mac and hold Cmd+R on startup. This will bring up the Recovery Mode. Open Utility -> Terminal from the menu bar and type csrutil disable Reboot.

Step 2: Manually add permission for Steam to access the microphone.

Open Terminal and type the following command:

sudo sqlite3 ~/Library/Application\ Support/com.apple.TCC/TCC.db"INSERT or REPLACE INTO access VALUES('kTCCServiceMicrophone','com.valvesoftware.steam',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1551892126);"

Enter your Mac password to confirm the action.

Step 3: Make Steam use that permission

In Terminal, type the following two commands:

/usr/libexec/PlistBuddy -c "Add NSMicrophoneUsageDescription string" /Applications/Steam.app/Contents/Info.plist

/usr/libexec/PlistBuddy -c "Set :NSMicrophoneUsageDescription Using voice chat" /Applications/Steam.app/Contents/Info.plist

Step 4: Enable The System Integrity

Reboot your Mac and hold Cmd+R on startup. This will bring up the Recovery Mode. Open Utility -> Terminal from the menu bar and type csrutil enable Reboot.

I followed these exact instructions and now my mac no longer connects to wifi networks. Any idea what's going on?

Guys, I have done the above step and I could see the steam listed for permission for the microphone. But now the only problem is that when I try to use the mic during the game, others can only hear static! Any idea what could be the issue?

Idk why but when I inserted the first command it starts SQLite terminal and when I add the next two commands nothing happens. Maybe is because I have installed mysql on my Mac?
I don't see Steam in my microphone permission list.

Quick thing : in the second command a whitespace before the sql code is missing! The correct command is:
sudo sqlite3 ~/Library/Application\ Support/com.apple.TCC/TCC.db "INSERT or REPLACE INTO access VALUES('kTCCServiceMicrophone','com.valvesoftware.steam',0,1,1,NULL,NULL,NULL,'UNUSED',NULL,0,1551892126);"
