Here’s how to set a screen saver password on Mac. This is why it might be a good idea to enable a screen saver password, so that even after you log on, your computer will lock itself down after a specific amount of time of inactivity. However, by default, once you’re logged in and you step away for a bit, someone can come by and get on your Mac without needing any credentials. However, it’s different than having a password that you enter to initially log onto your Mac, so when you first boot up your machine, you’ll be greeted with a login page where you’ll enter in a password in order to get to your desktop. Once your screen saver activates, your Mac locks itself down so that when you come back, you’ll have to enter in a password to use your computer again.Įssentially, it’s a security feature that prevents prying eyes from accessing your computer, even after you logged on. What’s the purpose of a screen savor password? Well, essentially it’s great if you’re in a public place and have to walk away from your computer for a bit. Your need may be driven by a different reason.It’s pretty easy to set a password for your Mac and have your computer require the password to log on, but here’s how to set a screen saver password that requires you to enter it every time you want to get back on your Mac. In my case, it can cause a lock up when the login screen sits idle too long. I’m testing this myself because I’ve occasionally seen problems with my graphics card and the process called ScreenSaverEngin. That is, sudo defaults write /Library/Preferences/ loginWindowIdleTime 0
(You’ll need to enter an Administrator password.) To stop the screen saver permanently, set NNNN = 0. Where NNNN is the delay in seconds before it kicks in. Instead use this terminal command: sudo defaults write /Library/Preferences/ loginWindowIdleTime NNNN However, the screen saver that kicks in after a period of time at the login screen is not controlled by that user setting. There, you can set it to the desired time on the bottom left where it says Start after: Or set to Never. The activation of the normal screen saver in OS X, after you’ve logged in, is managed with System Preferences > Desktop & Screen Saver > Screen Saver. NGC 3190, first used in OS X Mountain Lion.įirst. This might apply when, for example, the screensaver engine ( ScreenSaverEngin) is acting up, and you don’t want it to activate, ever. There may be times when you don’t want the OS X login screen saver to kick in.
