Why You Need to Change the Screen Lock Time

There are several reasons why you may need to change the screen lock time on your Mac. One of the main reasons is convenience. The default screen lock time on a Mac is set to a certain period of inactivity, which may not suit everyone’s needs. For instance, if you are frequently interrupted during work or study sessions, having a shorter screen lock time can protect your privacy while allowing you to resume your tasks quickly.

On the other hand, if you are using your Mac in a busy or public environment, a longer screen lock time may be necessary to ensure that your device remains secure when you step away. By adjusting the screen lock time to your preferences, you can strike a balance between convenience and security.

Another reason to change the screen lock time is power-saving. When your Mac locks the screen after a certain period of inactivity, it helps conserve energy by turning off the display. If you want to optimize power consumption and extend your battery life, customizing the screen lock time is an effective way to achieve this.

Method 1: Via System Preferences

Changing the screen lock time via System Preferences is the most straightforward method. Here’s how you can do it:

Step 1: Click on the Apple menu in the top-left corner of the screen and select "System Preferences."
Step 2: In the System Preferences window, click on "Security & Privacy."
Step 3: Navigate to the "General" tab and click on the lock icon in the bottom left corner of the window to make changes. You may need to enter your administrator password.
Step 4: Once the lock icon is unlocked, look for the option labeled "Require password" and select your preferred time interval from the drop-down menu.
Step 5: Close System Preferences.

Step 2: In the Terminal window, type the following command and press Enter:
defaults -currentHost write idleTime [time in seconds] "`
Replace "[time in seconds]" with the desired screen lock time in seconds. For example, if you want to set the screen lock time to 10 minutes, you would enter "defaults -currentHost write idleTime 600" (10 minutes x 60 seconds = 600).
Step 3: Once you have entered the command, press Enter. You may be prompted to enter your administrator password.

Step 1: Open Script Editor. You can find it in the Utilities folder within the Applications folder.
Step 2: In Script Editor, enter the following AppleScript code:

delay [time in seconds] tell application "System Events"
keystroke "q" using {control down, command down}
end tell

Replace "[time in seconds]" with the desired screen lock time in seconds.
Step 3: Save the script with a meaningful name and the file format as an application.
