The problem is, the Mac doesn’t offer a black screensaver. However, a screen saver is most useful as a screen lock indicator.

However, some LCD screens can show latent imagery under certain specific conditions if left sitting with the same static image for too long. With either of the LCD or OLED technologies, the chance for burn-in is almost non-existent. Some screens are made of OLED technology, which means that each pixel is a self-illuminated RGB LED light. Since the days of CRT tubes have long since passed, we are now using LCD screens with LED back or side lights. It’s also distinctly different from power saver mode. No, it doesn’t turn off the backlight, but that’s a small problem.Ī little history, a screen saver was used primarily to prevent burn-in on CRT tubes. So, I avoid the energy saver system like the plague to avoid random VPN disconnection. Unfortunately, I have no control over the software that’s used by my company and I have to live with it. If your company invests in VPN software which does not self-connect on WiFi reactivation, you’re stuck reentering your passwords and setting up your terminals all over again. This means that if you have a VPN running, your VPN will disconnect. Unfortunately, with that it also turns the WiFi and networking off.

“What problems”, you ask? Well, Apple has taken it upon themselves to also shut down a number of other critical components when the power saver is activated. While this works to turn off the backlight and save it, power savings does other unfortunate things to a MacOS computer at the same time. What people have suggested instead of a black screensaver is to enable the energy saver.

One of the things you’ll notice in the screensaver area is that there is no blank or black screen saver. I’m starting with the Mac because it seems so much less obvious considering how ‘easy’ it should be for a Mac. I also realize that Windows offers a Blank screen saver that kind of negates this technique, but here it is anyway. This technique should work on any desktop operating system and this technique is quite easy to set up.
