Although you may occasionally want to change time zones as you travel, you rarely need to adjust the date and time on your Mac laptop if you select the option to set date and time automatically. However, if that day comes, you can make the adjustments in the Date & Time preferences screen, which you open by clicking on the ​time indicator at the top right corner of your Mac's menu bar.

If the Date & Time screen is locked, click on the lock icon in the lower left corner to unlock it and allow changes.

Uncheck the box next to Set date and time automatically. Click on the clock face and drag the hands to change the time, or use the up and down arrows next to the time field above to the digital clock face to adjust the time. Change the date by clicking the up and down arrows next to the date field above the calendar.

Note: If you just want to change time zones, click the Time Zone tab and select a time zone from the map.

The final step you need to take is to click on the lock icon so no one else can make any further changes, and the adjustments you just made will stay in effect until you need to change the date or time again.
