Turning Off Auto Lock on a Mac

To turn off auto lock on your Mac, open System Preferences from the Apple menu. Select Security & Privacy, then select the General tab. Uncheck the box next to “Require password [time interval] after sleep or screen saver begins”. This will disable auto lock and your Mac will no longer be locked after a period of inactivity.

Increasing the Screen Timeout on a Mac

To get your Mac screen to stay on longer, you can adjust the settings in System Preferences. On your Mac, choose Apple menu > System Preferences, then click Lock Screen in the sidebar. From there, you can select a time interval from the pop-up menu next to “Turn display off on battery when inactive” on the right. Depending on your needs, you can choose an option ranging from 1 minute to Never. Once you’ve made your selection, click the “Lock” button in the bottom left corner of the window to save your changes.

The Reasons Behind Mac Auto-Locking

Your Mac keeps auto-locking becase your Energy Saver settings are set to put your Mac into sleep mode after a certain period of time. To adjust your Energy Saver settings, choose Apple (?) menu > System Preferences, then click Energy Saver. Here, you can adjust the time until your Mac goes to sleep and when the display dims or turns off. Additionally, if you have FileVault enabled on your Mac, you can also adjust whether or not the screen locks when it goes to sleep.

The Causes of Quick Sleep Mode Activation on Mac Computers

Your Mac goes to sleep so fast bcause of macOS’ default power efficiency settings. macOS is designed to be as energy efficient as possible, so when you stop using your Mac for a certain amount of time, it automatically goes to sleep in order to conserve power and prolong battery life. You can adjust the automatic sleep settings in System Preferences if you’d like, but bear in mind that doing so may reduce your battery life if you don’t actively monitor the energy usage.

Adjusting Screen Timeout Duration

To change how long the screen stays on, go to the Display settings menu. Look for the Screen Timeout option and tap it. You can then choose the timeout duration that best suits your needs — the default is 30 seconds, but you can adjust it to 15 seconds, one minute, two minutes, five minutes, 10 minutes, or even 30 minutes. Once you have selected your desired duration, simply press ‘OK’ and your new setting will be saved.
