Part 1. Why is Mac Left Click Not Working?

Before we discuss the fixes, it's essential to understand what is actually causing the issue. Once you know the reason, you can fix it precisely.

Here are some common reasons why the left click is not working on Mac.

• Another Mouse is Connected: If you had previously connected a mouse to your Mac and forgot to disconnect it, it can interfere with the functioning of your primary device and cause the left click to fail.
• Bluetooth Issues: You might be using a Bluetooth mouse that’s not correctly paired or has a low battery. This can cause delays in the clicks or loss of click recognition.
• Mouse or Trackpad Problems: Your mouse or trackpad itself might be damaged, dirty, or have hardware issues. This can affect their overall performance.
• System Glitches: If you’ve recently installed a system update, there might be some corrupt settings or minor glitches interfering with your trackpad’s performance.

Part 2. How to Fix Left Click Not Working on Mac? 7 Fixes

No matter what’s causing the left mouse click not working on Mac, there are 7 proven ways to fix it. Go through the following fixes to find the one that works for you.

Fix 1. Disconnect the Incorrect Mouse

If you had previously connected a mouse to your Mac but forgot to disconnect it, it may be causing the issue. You need to disconnect this device so your current mouse or trackpad can work normally.

Here’s how to do it.

1. Click the Apple icon in the top left of the menu bar.
2. Select “System Settings” and choose “Bluetooth.”
3. Find the mouse or device you aren’t using and click the “i” icon next to it.

4. Choose “Forget This Device.” Then select “Forget Device” again to remove it.

Fix 2. Turn Off, then, On Bluetooth

Another way to fix the Mac left click not working is to refresh your bluetooth connection. You can do this by turning the bluetooth off/on. This will help fix any glitches between your Mac and trackpad.

Here’s what to do.

1. Click the Control Center icon from the top menu and select “Bluetooth.”

2. Toggle off the “Bluetooth” option at the top.
3. Wait a few seconds. Then, toggle the Bluetooth back on.

Fix 3. Re-pair the Mouse or Trackpad

Another way to refresh your device’s connection is to disconnect your mouse or trackpad and then reconnect them. This method works if there are issues with the connection itself and not the hardware of your device.

Here’s how it works.

1. Click the Apple menu > System Settings (or System Preferences).
2. Select “Bluetooth.” Then, locate your mouse or trackpad in the device list.
3. Click “Disconnect” next to your device name. Alternatively, Click the “i” icon and select “Forget This Device.”

4. Turn off your mouse or trackpad. Then turn it back on. Wait until it appears under available Bluetooth devices. Then, click “Connect.”

Fix 4. Use Another Mouse

If the left click on mouse is not working on Mac despite taking the above steps, try using a different mouse instead. This will help clarify whether the problem is related to the device or to your Mac’s system. If the new mouse works fine, the previous device might be faulty due to a broken switch or damaged sensor. However, if the problem persists, you can try the next fix.

Fix 5. Use Shift Key Magic

If the left click still doesn’t work even after changing the mouse, there might be a glitch with the Mac’s system. The Shift key method will put your Mac in Safe Mode, which helps repair any software issues.

Here’s how it works.

1. Click the Apple icon in the top left and choose “Shut Down” to turn off your Mac
2. Now, turn your Mac back on and immediately press and hold the Shift key.
3. Keep holding until a rotating circle appears (not the beachball).
4. Wait until a progress bar appears under the rotating circle. Once it fills up completely, your screen will go black.
5. Then, your Mac will restart and prompt you to open or close your previous session. Click “Open” to restore your desktop.

Fix 6. Restart The Mac

Sometimes, a simple restart is all you need to fix the left click on Mac not working. A quick restart will refresh the system settings and fix any temporary glitches.

Here’s how to restart your Mac.

1. Click the Apple logo in the top-left.
2. Select “Restart” from the menu.
3. Click “Restart” again to confirm your action.

Fix 7. Update the macOS

Another solution to resolve software issues is to update your Mac. New versions contain fixes for any hardware or software issues and can be helpful if Mac left click stops working.

Here’s how to install updates.

1. Go to the “Apple” menu > “System Settings” or “System Preferences”.
2. Select the “Software Update” option.

3. Wait for your Mac to check for available updates. If an update appears, click “Upgrade Now.”
4. Click “More info” to view and install additional updates. Then, restart your Mac.
