Mac OS X Lion doesn't come with a "black screen" screensaver. Where can I get a screensaver that works with Lion and blanks the screen?
I uploaded this for you, you can download the screen saver file here.
If you want to do it manually, do it like this:
- Open Quartz Composer.app. This is no longer ships with Xcode by default. You need to install Xcode first and then download the Graphics Tools for Xcode. Be sure to download the appropriate version. I copied the application files to
/Applications/Xcode.app/Contents/Applications/so they are listed under
Xcode->Open Developer Tool.
Create a new blank file with the Screensaver template. Delete everything except for the "Clear" panel. You can also start with a totally empty window and drag "Clear" from the Patch Library to the work area.
Save it under
/Users/your-user/Library/Screen Saversto make it available for you only, or
/Library/Screen Saversto make it available for all other users. Doing the latter, you'll have to enter an admin password.
- Then, select it in System Preferences under "Other".
And there you go, a simple black screensaver.
Alternatively, you could of course just put the monitor to sleep, or let it display a folder of pictures, which only has one black picture inside.
Just get this one, it worked fine for me on 10.6 and now on 10.7:
There it is, THE REAL screensaver. Since this screen saver will only display a black blank screen it should actually save your screen. Of course, if you REALLY want to save your screen use the "Energy saving" settings in your system's preferences. Now featuring transparency! It's Freeware, so don't hesitate to Media:Blankscreensaverfolder120.zip download the 1.2.0 version (for Snow Leopard).
