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.
