Logical successor to Caffeine

I loved Caffeine. It was elegant. It was simple. Alas, it became unmaintained.

This app is the logical successor. I like it enough to give it 4 stars. I didn’t give it 5 stars because it is overly complicated and as a result the User Experience can be a little confusing. Example: Anti-Sleep System vs. Anti-Sleep Display: My hypothesis is that most users will likely not care about the difference, or even make a differentiation in thier minds eye. Instead most users will think about on and off, is my computer on or off. As a result, having switches for system vs. display doesn’t really give me a good feel for what behavior is expected. Part of the challenge is that Macos doesn’t give users a great way to just “lock the screen” when they walk away, like is possible on Windows. It is, gasp, a Macos design flaw. Yes, I can hit Shft+Cmd+Q to lock the screen, but then what is the system behavior? The answer is nebulous beyond the fact that the screen is locked.

I miss caffeine. i can’t use this

i was stunned to find caffeine missing when i received my new imac and i downloaded antiSleep. now, everytime i wake my iMac, all my usb memory drives have their connections broken, and any applications tied to them crash. i futzed with its click down menu, but i can’t seem to tune it to stop causing my external memory devices from disconnecting such that the system is warning me that i am not closing them down correctly. this isn’t something i can sit down to four or five times a day. sorry. so, in my experience, the software is broken and unusable and i guess i’ll either have to pay for one or crack open the sdk and write one myself. but i will say, since 677 users find no problems with it, either i am missing something obvious, or i am the only one that keeps necessary data for an application on a usb link. worse, if the data on the disk were to be corrupted by this, i would be up the creek. so it isn’t even safe for me to use this software. maybe i set it up wrong, but i can’t seem to figure it out from the menu, and i’ve been using software since the early 1980s, and i don’t have the patience to contact them and work through it for what is really something they introduced in replacing caffeine. i don’t like slamming coders, because i was once one, and i’m sure they’re good people. they must be. they are not writing for microsoft :-)

I sincerely regret that the application did not like you. Try the new version, it is much more stable and has more powerful functionality, including work with external devices. If you need additional features, please write to me at

How do I give it 6 Stars?

For many years I used Caffeine as my anti-sleep app. But a couple years ago I realized it had been discontinued and no longer available on the Mac App Store. Then I discovered Amphetamine which added many wonderful features but that hasn’t been updated since High Sierra and its features no longer work.

Then today I discovered AntiSleep and couldn’t be happier. It does everything I want and so much more. If it has any problem it’s that there are too many wonderful features to choose from 😀. The developer really thought this through!

It took me next to no time to purchase a year’s subscription for the modest $3.99 to unlock all of the features. If you’re looking for an anti-sleep app look no further!
