Glowix

Glowix does one thing and does it well: it keeps your Mac display awake when you need it. No more awkward pauses during presentations when your screen goes dark mid-sentence. No more frantically waving your hand at the sensor during a coding demo or important call. It's that simple—toggle it on, your screen stays on, toggle it off, normal behavior resumes.

Look, macOS has had this capability buried in system settings for years, but nobody wants to dive into Energy Saver preferences every time they need to give a talk. Glowix puts that control right in your menu bar with one click. It's the kind of utility that once you have it, you can't imagine going back. It's free, it's lightweight, and it solves a problem you didn't realize was annoying until it wasn't.
