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 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 read some of the reviews and I can't disagree that for some people a lock screen button might be nice and an interface that works like their brains. I just turned it on and it kept my Mac awake during some long tasks that had quit because of sleep. Price seem reasonable. After using it for awhile I bought the pro family version to encourage the developer to keep going. As with all programs I have at times it is hard to understand all the options. As I said I turned it on and left my laptop doing something and it allowed the laptop to complete the multi-hour task. Tonight I am turning on some new features that let the screen sleep and even function while the lid is closed. As with all things I may come back in a week and the computer is still on and I forgot because the screen was off and the lid closed. people do dumb stuff like this. Overall a pretty good program at a pretty good price.

I've been using Sleep Control Centre for several years. Every update has simply expanded the already-powerful features. So much better than the native OS settings and certainly better than other MacOS Apps I've seen.I set my default settings pretty aggresive, since I usually work with my Macbook Pro attached to external power, a mionitor, and one or more external drives. So I prevent my laptop from system sleep, display sleep, external drive sleep, and prevent it from going into sleep mode because the screen/lid is closed.When I want to switch back to the more typical default settings, I can either click on the App icon in the menu bar to disable it or, since I set it to deactivate when I'm, not connected to external power, I can just unplug the USB-C power cable. The second option is easiest, but both work.I can set it to automatically activate everything again just by plugging the power back in. Or, I can leave that open off and just do it with a click in the menu bar.Pavlo has been on top of every update over the five or more years I've been using Sleep Control Centre. I don't know about customer support because I've never needed it. Again, I wish that were always true.
