2 Ways to Fix WhatsApp Calls Not Working on Mac

Quick Tips

• Enable the mic and webcam on your Mac for WhatsApp.
• Force quit and relaunch WhatsApp on your Mac.

Basic Fixes

• Check your internet speed: WhatsApp calls need a stable internet connection. So, ensure you have connected your Mac to a high-speed Wi-Fi network.
• Disable Low Data Mode for Wi-Fi: If you don’t have any daily data limits on your Wi-Fi network, we suggest disabling Low Data Mode on your Mac.
• Ensure that other apps are not using camera or microphone: If there’s an app running on your Mac that’s already accessing the microphone or camera, it can cause such issues.
• Update or Reinstall WhatsApp: You can update the current app version or reinstall WhatsApp on your Mac.

Fix 1: Check Microphone and Webcam Permissions

Step 1: Open System Settings and go to Privacy and Security from the left menu.

Step 2: Scroll down and click on Microphone. Then, check whether WhatsApp is allowed to use it. If not, enable the permission.

Step 3: Go back and click on Camera to check the same.

Step 4: Once done, click on Screen Time from the left menu and select App Permissions.

Step 5: Ensure the permission for Camera is enabled. Click on Done at the bottom to save changes.

Fix 2: Run SMC Reset

You can use the SMC reset option if you have a Mac running on an Intel processor.

Step 1: Press and hold the Power Button till your Mac shuts down.

Step 2: After your Mac shuts down, wait for a few seconds and press Shift + Left Option + Left Control key. Press and hold the Power Button as well.

Step 3: Keep pressing the four keys for another 7 seconds. If your Mac turns on, it will play the default startup chime again while you hold down those keys.
