Don't let your Mac fall asleep.

Overview

Caffeine is a tiny program that puts an icon in the right side of your menubar. Click it to prevent your Mac from automatically going to sleep, dimming the screen or starting screen savers. Click it again to go back. Hold down the Command key while clicking to show the menu.

The menu now has a sub-menu for deactivating Caffeine automatically after a number of minutes.

What a useful little app! The addition of a setting for a default duration makes this even easier to use.

You'll be happy to hear that improvements in the menu bar icon are on the way :-)

Just discovered that this function is built in! Just type 'caffeinate' into a terminal window. Add “-t xx” to specify duration in seconds. So -t 3600 for an hour.

Oh, that's awesome. Thanks for the heads up on this!

It just does what it supposed to do. One of the first apps I always install on new Macs. But currently, on Yosemite, it keeps "selected" after a click to make it Active.

Strange. It worked fine for me in Yosemite, and in El Capitan, and now again in macOS 10.12 Sierra. It does indeed stay selected when I right-click (or control-click) the menu icon. But I never need to do that. I simply click to activate and click again to deactivate.

I tried the following programs Amphetamine, Caffiene. Anti Sleep. I like Anti Sleep best, especially for the new MacBooks with Haswell chips that no longer have a 'Never Sleep' option under Power Preferences. Here's what I like in Anti Sleep:
1) has a auto launch/auto activate on system startup option, great for remote systems, like a laptop, that need to be always on for access. No human needed to activate.
2) Has options to only activate when powered by AC, versus battery, or both. Again, great for laptops.
3) Display sleep can be set separately from machine sleep.

I provide remote assistance to family. When they need me to look at something on their system, I just need to tell them turn on the laptop, plug it in, leave the lid up. They don't even need 'activate' since it is set to auto launch and activate if AC power is on. I can then log in anytime thereafter, even late night. I set options auto launch/activate at startup, activate only when AC is on, and stay awake indefinitely.

Re option 1) You can do this manually by adding to Login Items in Accounts preferences (System Preferences) . The app just does it for you more easily
Options 2 & 3 are nice options

"Re option 1) You can do this manually by adding to Login Items in Accounts preferences (System Preferences) "

Yes, true, and for geeks like us, that's okay, but for non-techies, like in my family, I try not to encourage them to mess with Login items. True story, I showed an in-law once about Login items. Week later, he calls me complaining his system has a virus, he's been hacked, etc. I asked, "what makes you say that?" He says, "It's really slow when I turn it on, and I can't do anything for several minutes, and the beachball spins, like somebody is accessing my computer." Well, he had added like 20+ apps to Login Items at startup. "Why did you do that?" I said. "These are the apps I use the most, I want them all available as soon as my machine is turned on." And funny, when I tried to explain why that would slow down his mac at boot, he just couldn't grasp it, because when he launches indivdually, they load (from his perspective) almost instantly. LOL...so yeah, gotta be careful not to give people too much rope :-)

also for non techies, I believe it is critical to have the program recognize if the mac is running on battery and have an option to disengage. Non techies who just unplug power and close the lid, without thinking, will risk draining the battery dead and worse, overheating the laptop.

After the apparent abandonment of Caffeine by its developer and its not support the retinas screens and Dark mode on Yosemite, I decided to look for a replacement the height! I found the incredible Wimoweh also that works perfectly and has several more options including: not let Mac sleep but allow the monitor to sleep. Found it amazing! S2

I love this app...but it needs to be updated for Yosemite. Sometimes the menu icon blacks out and the only way to fix it is to exit/relaunch.

Is there a way to suppress the preferences window at launch? It's a bit of an annoyance to have to manually close the prefs window every time the app launches--they can be accessed via right clicking the menu bar icon, so I see no reason we should be faced with the prefs every time the app starts. Is there a way to change this that I'm missing?

Version 1.1.1

Does what it says. It wont let the comp sleep, unless you close the lid. I wanted something where I could close the lid too, and this just inst the solution. NoSleep seems to do the job better.
