Prevent your computer from going to sleep
If you have problems with your PC locking or going to sleep, caffeine will keep it awake. It works by simulating a keypress once every 59 seconds, so your machine thinks you're still working at the keyboard, so won't lock the screen or activate the screensaver.
The icon is shown above - it's the leftmost one in the task tray, and this is all you see. Double-clicking the icon empties the coffee pot (that's what the icon is) and temporarily disables the program. Double-clicking it again refills the pot, and will keep your machine awake.
By default the app starts enabled, and works every 59 seconds. Picsart pc software, free download. There are some command line switches you can use to alter this behaviour:
xx- where xx is a number which sets the number of seconds between simulated keypresses. This must be the first text on the commandline-startoff- application starts disabled.-exitafter:xx- application will terminate after xx minutes-activefor:xx- application will become inactive after xx minutes-inactivefor:xx- application will become active after xx minutes-appexit- terminates current running instance of application-appon- makes the current running instance of the application active-appoff- makes the current running instance of the application inactive-apptoggle- toggles the running state of the current running instance of the application-apptoggleshowdlg- toggles the running state, and shows dialog-replace- closes the current running instance, replacing it-noicon- does not show a task tray icon-useshift- simulate the shift key instead of F15-showdlg- shows a dialog indicating whether caffeine is active-ontaskbar- show a task bar button (use with -showdlg)-allowss- prevent sleep, but allow the screensaver to start-key:xx- simulate using virtual key code xx
Note: the codes on the linked page are in Hex, convert them to decimal for use with this parameter-keypress- simulate a full key press, not just a key up event-oldicons- use more colourful tray icons-darkicons- use icons which work better for dark-on-light colour schemes-watchwindow:xx- active only when a window with xx in the title is found-activehours:....xxxxxxxx....- put 24 . or x characters - which indicate from hour 0 to hour 23 of the day.

Compatibility
Download Caffeine 1.1.3 for Mac from our website for free. Commonly, this program's installer has the following filename: caffeine1.1.1.zip. The application can also be called 'Caffeine 2', 'Caffeine.1', 'Caffeine-1'. The following version: 1.1 is the most frequently downloaded one by the program users.
Caffeine works by simulating an F15 key up event every 59 seconds. Of all the key presses available, F15 is probably the least intrusive, and least likely to interfere with your work.
Caffeine App Mac
However, Caffeine might interfere with some apps:
- PowerPoint uses the F15 keypress to pause video in a slide
- Google Docs/Sheets
- Smartsheet
- Terminal emulation, e.g. Putty
If you think any of these might cause you a problem, set the -useshift command line parameter.

There are numerous ways that your computer system saves energy where it is not required. The most commonly noticed method of saving energy is to put the computer to sleep after a short period of inactivity. But this can be a hassle for many users who rely on their computers to do research or take notes from the information on the screen. Although the computer marks this as an inactive period, it hinders the user's work when the screen shuts down.
Caffeine App Windows
Caffeine for Mac is a great solution to this issue. It allows the user to select the period for which they would like their computer to stay on and active. There are several features that make this tool stand out, here are some of them-
Easy Access
You can manage to change the amount of time for which the screen will remain active and each time you decide to change the duration, all you have to do is click on the menu bar. If you press the command key at the same time, it will bring the program menu where you can manage to find the shortcut to change the time duration you have selected.
Sub-Menu
Caffeine for Mac is a great tool that gives the user the maximum amount of freedom. It has a sub-menu that is set up especially to make sure that the user can quickly activate or deactivate the tool and choose the time for which the system will remain active. This is a great way to save time and make the task of monitoring your computer screen easier.
