Solutions to fix Caps Lock stuck on Mac
In this section, we will provide six solutions to fix the issue:
Utilize the Accessibility Keyboard
Using the Accessibility Keyboard can help identify physically stuck keys.
Follow the steps given below to access the Accessibility Keyboard on Mac:
Step 1: Head to Apple menu > System Preferences > Accessibility > Keyboard.
Step 2: Enable the Accessibility Keyboard and inspect for stuck keys.
If any are found, unstick them or clean the debris under the keys using compressed air.
Keeping your macOS and built-in apps up to date is crucial for security and performance.
To install updates and upgrades, follow these simple steps using Software Update:
Step 1: Navigate to Apple menu > System Settings.
Step 2: Click General on the window’s left side, then select Software Update on the right.
If Software Update detects any new software compatible with your Mac, click on the install button. During installation, your Mac might display a progress bar or blank screen multiple times. It’s essential to avoid putting your Mac to sleep or closing the lid during this process.
Use an external keyboard
Another way to fix the Caps Lock stuck on the Mac problem is by using an external keyboard. If nothing, using an external keyboard will help narrow the list of probable causes.
If the Caps Lock key works fine on the external keyboard, your MacBook’s keyboard is damaged. However, if the Caps Lock problem persists, it indicates a problem with the software.
Reset NVRAM and SMC
Resetting NVRAM has effectively resolved the Caps Lock stuck on Mac issue.
For M1 Macs, shut down and power on to reset NVRAM.
On the other hand, for Intel Macs, shut down, then press and hold Option-Command-P-R while powering on until you hear the second startup sound (T2 Macs) or see the Apple logo appear and disappear twice (non-T2 Macs).
Safe boot your Mac
Safe Mode on macOS is similar to its Windows counterpart, serving as a troubleshooting tool to isolate software issues from hardware failures.
In Safe Mode, your Mac loads only essential drivers and software, omitting startup items. This helps diagnose and resolve software conflicts and triggers a check of the startup disk.
Shut down the Mac, then press and hold the power button until the Loading Startup option appears. Press and hold the Shift key, and select Continue in Safe Mode.
Disable Caps Lock
You can prevent future problems by temporarily disabling the Caps Lock key.
Step 1: Head to Apple menu > System Preferences > Keyboard.
Step 2: Select Modifier keys.
Step 3: Select your keyboard from the drop-down menu. Now, select the drop-down button corresponding to the Caps Lock and select No Action.
By implementing these four effective solutions, you can resolve the Caps Lock stuck on Mac issue and enjoy seamless typing without frustration.
