When the clock on MAC OSX goes off

To sync your macOS clock and prevent it from drifting after sleep cycles, follow these steps:

- Run this command to sync time:

sudo sntp -sS time.apple.com

- Go to System Settings > Date & Time and turn off "Set time and date automatically."

- Remove the current time settings:

sudo rm /var/db/timed/com.apple.timed.plist

- Reboot the Mac.

- After reboot, turn on "Set time and date automatically" in System Settings > Date & Time. This should ensure your clock remains accurate.
