NapZap is a macOS menubar app that stops your Mac from going to sleep. You can activate it indefinitely or set a timer so it turns off automatically when your task is done.
No. NapZap uses negligible CPU and barely registers in energy impact. The only power cost is from your Mac staying awake, which is the whole point.
Click the menubar icon. One tap activates NapZap, another deactivates it. You can also set a duration from the menu if you want it to stop automatically.
Yes. NapZap works at the system level, not per-app. Whether you're rendering in Final Cut, downloading in a browser, or showing slides in Keynote, it keeps your Mac awake.
Long video renders, large file downloads, presentations, cooking with a recipe on screen, reading without touching the trackpad, remote access sessions. Anything where sleep mode would get in the way.
