The Ultimate Safe macOS Awake Tool

Apple’s macOS is incredibly efficient at saving battery life, often putting your Mac to sleep right in the middle of a large file download, a complex video render, or while you are reading a long document. While apps like Caffeine or Amphetamine exist, many users cannot—or prefer not to—install third-party software on their pristine Apple Silicon devices.

Move My Cursor is the ultimate web-based solution to prevent Mac sleep mode. It utilizes modern web standards available in Safari and Chrome to instruct macOS to keep the display and hard drive active. It offers the exact same power as native macOS apps but with zero downloads, zero disk space used, and zero security warnings from Apple's Gatekeeper.

macOS Sleep FAQs

Does this work on Apple Silicon (M1/M2/M3) Macs?

Yes. Because it runs natively inside the web browser, it is perfectly optimized for all macOS architectures, including Intel and Apple Silicon.

Will my Mac still go to sleep if I close the lid?

Closing the lid of a MacBook triggers a hardware-level sleep command called 'Clamshell Mode'. You must keep the lid open (or connected to an external display) for the tool to work.

Is this safer than downloading an app from outside the App Store?

100% safer. You do not have to bypass Apple's Gatekeeper or grant deep system permissions to an unknown developer.
