How do I know if my Mac update is stuck?

If your Mac update appears to be stuck, the first step is to allow it some time. Depending on the size of the update, it may take several minutes or even hours before it completes. If after waiting an extended period of time and you still see no progress or activity in the update window, then it is likely that your Mac update is stuck.

If this happens, try resetting your Mac’s System Management Controller (SMC). To do this, turn off your computer and press and hold the power button for 10 seconds while connected to a power source. Then release the power button and turn on your computer again. This will reset certain low-level settings related to power management and should help resolve any issues with your Mac update becoming stuck.

If you have tried resetting the SMC but are still experiencing issues with a stuck Mac update, contact Apple Support for further assistance.
