Welcome to Amphetamine4, the most awesome keep-awake utility ever created for macOS. Amphetamine can keep your Mac, and optionally its display, awake through a super simple on/off switch, or automatically through easy-to-configure Triggers.

If you have problems with your PC locking or going to sleep, caffeine will keep it awake. It works by simulating a keypress once every 59 seconds, so your machine thinks you're still working at the keyboard, so won't lock the screen or activate the screensaver.

Inspired by the Mac OS X version, Caffeine for Linux is a status bar application able to temporarily prevent the activation of both the screensaver and the "sleep" powersaving mode.

Caffeine is a tiny program that puts an icon in the right side of your menu bar. Click it to prevent your Mac from automatically going to sleep, dimming the screen or starting screen savers. Click it again to go back. Hold down the Command key while clicking to show the menu.

Annoyed by the display getting dim when you're reading or watching something? What if the computer could “see and hear” you?

KeepOn is free and open-source (FOSS), without any ads/tracks and no Internet use.

Coffee allows you to keep the display awake without having to change the device settings. It can be toggled at various places:

Keeps your Mac awake.

It always has been a missing feature: disabling the sleep mode on a Apple Laptop. Who does not want to use it as a big juke-box or go warwalking. The best looking server ever, especially at about one inch height.

Prevent your Mac from falling asleep, dimming your screen or starting the screensaver. Theine keeps macOS awake just like caffeine does with you.
