Keep your Mac awake with caffeine

Our Macs work hard, and sometimes they get sleepy. But that doesn't mean they can slack off on the job! To keep your Mac alert and ready to go, check out Caffeine. It's a tiny little app (and at 48KB, we mean tiny!) that puts an icon in your menu bar. Give it a click to prevent your Mac from going to sleep, putting the disk to sleep or dimming the screen. Click again to remove these restrictions. It's quicker than launching system preferences and adjusting those settings manually, and convenient for those overnight downloads. Caffeine is universal and free.

Alternatively, try out Jiggler, which periodically "jiggles" your cursor to prevent your Mac from sleeping or launching a screensaver. Like Caffeine, Jiggle is universal and free. Now tell your Mac to get to work!

My stupid company dell doesn't allow me to change the sleep settings, so does anybody know of a similar tool for Window$ ?

I installed this on my MacBook and now it never gies to sleep when inactive, whether Caffiene is active or not. I have even quit Caffeine and dragged the app to teh trash. Still no sleep. My display dims as scheduled but my MacBook never sleeps. A caffeine headache.

Great, but i'd love it if i could CLOSE my macbook lid and it doesn't sleep, becuase that's what i thought it could do!

I need something the opposite. Something that will put my DP to sleep. Somewhere along the line with 10.4 it started refusing to go to sleep.

It always wakes up again right at the point which would seem to be the power down of the drives etc.

"16. This app would be perfect if it was a little more customizable. I'd like to keep my Mac on but let the display still automatically shut off, and this program keeps the display on. Not very useful for all-night downloads...unless you don't mind wasting all that energy..."

go to the energy saver prefpane, set "put the computer to sleep" all the way to the right [never] and then set "put the display to sleep" to whatever timeout you want. simple.

"6. I don't think there *is* a system preference to prevent your monitor from dimming automagically... so this is super handy!"

in the energy saver prefpane, click on options, then deselect "automatically reduce... before display sleep"

then you can just turn off sleep [or turn the time out a long way up]

"8. Don't you think you oughta give Gruber, over at "Darling" Fireball, a hat tip or a shout out?"

yeah, seriously. it's not like he mentioned one, and not the other, you basically just stole his two posts and put them into one.

I know that's a screensaver, but I think it does what you want. you could set a hot corner to start the screensaver and it would work. but I just know there's another app out there that's exactly what you're looking for... I just can't remember the name
