Caffeine1.1.4

Caffeine keeps a Mac from entering sleep mode when you need it to remain awake. It addresses the interruption caused by automatic sleep during an extended task, presentation, monitoring session, or other period when the computer must stay available. Activate the utility for the required period, then stop using it when normal sleep behavior is appropriate again.

Its purpose is deliberately narrow: it prevents system sleep rather than serving as a general power-management suite. That focused behavior makes Caffeine useful for Mac users who want a direct way to keep an active session running without changing the task itself. It is intended for everyday situations in which sleep would interrupt work or leave the computer unavailable.

Caffeine runs on MacOS and supports both Intel and Apple Silicon hardware. The current release is version 1.1.4, and it is distributed as freeware. No companion software, subscription, account, or additional hardware requirement is specified for using its sleep-prevention function.
