KeepingYouAwake vs Caffeine – which is better for macOS?

KeepingYouAwake is inspired by Caffeine but uses Apple's modern `caffeinate` tool, offering better reliability and integration with recent macOS versions. Caffeine hasn't been updated in years, so KeepingYouAwake is a more maintained and secure choice.

How to install KeepingYouAwake without using Homebrew?

You can download the latest version directly from the GitHub releases page or the official website at keepingyouawake.app. Simply drag the app to your Applications folder to install it manually.

Does KeepingYouAwake work on a MacBook with the lid closed?

No, it does not work with a closed lid due to macOS limitations and thermal considerations, as clearly stated in the README. It's only effective on desktop Macs or portables with an open lid.

Is KeepingYouAwake safe to use on my Mac?

Yes, it's based on Apple's official `caffeinate` command-line tool, which is inherently safe. However, the developer cautions users to employ it at their own risk, as with any utility software that alters system behavior.

Can I schedule KeepingYouAwake to activate at specific times?

No, KeepingYouAwake does not include scheduling features; it's designed for manual activation with preset or indefinite durations. For automation, you'd need to use the `caffeinate` command directly or another tool.

What macOS versions does KeepingYouAwake support?

It supports macOS 10.13 and newer, with legacy releases available for older versions like Sierra (10.12) and Yosemite (10.10). Check the README for specific download links if you're on an older OS.
