Caffeine App Alternatives Mac
Prevent your computer from going to sleep
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.
The icon is shown above - it's the leftmost one in the task tray, and this is all you see. Double-clicking the icon empties the coffee pot (that's what the icon is) and temporarily disables the program. Double-clicking it again refills the pot, and will keep your machine awake.

Compatibility
Caffeine works by simulating an F15 key up event every 59 seconds. Of all the key presses available, F15 is probably the least intrusive, and least likely to interfere with your work.
However, Caffeine might interfere with some apps:
- PowerPoint uses the F15 keypress to pause video in a slide
- Google Docs/Sheets
- Smartsheet
- Terminal emulation, e.g. Putty
If you think any of these might cause you a problem, set the -useshift command line parameter.
