The popular menu bar app Caffeine, which keeps your Mac from entering sleep, does not work by default under macOS Mojave (10.14). The original developer has not released a fix.
If you’ve had the situation where you were not actively using your computer, but did not want it to sleep, you may have been frustrated. You can of course disable the sleep options temporarily. But that is annoying, and maybe you will forget to enable them when your current task is done. That is why many people used the app Caffeine. It would make your Mac stay awake indefinitely, and it was easy to use. You simply clicked an icon in the task bar to enable or disable it. But with Mojave, Caffeine stopped working.
There are a few ways to fix it or replace it:
- There is an updated version 1.1.2 from another source who has taken over the app’s development, which reportedly works.
- You can manually make some changes to macOS’s Privacy settings to get the original app to work.
- Another free app that does the same thing is KeepingYouAwake. Although the options for this app are pretty minimal, it is an open source GitHub project, which may appeal to some people.
- Another free app with very robust features and great ratings in the Mac App Store is Amphetamine. It is by far the most advanced app in its category that I have seen. It offers a wide variety of triggers and time options for keeping your Mac awake. This is the solution that I am currently using.
Another app that offers this feature is Theine, available for $3.99 from the Mac App Store (https://itunes.apple.com/app/theine-2/id955848755?mt=12&ign-mpt=uo%3D4). It does not seem to do anything that the free app Amphetamine doesn’t do.
