Hi guys and gals, I was super annoyed with the pixelated mess that was the caffeine menubar icon so I made a new app icons for it, in a higher res and in the more abstract style that apple is using now. Since the incident I’ve conducted a bit of research and came across Caffeine, a free app that prevents your Mac from sleeping. The app can be toggled on/off with one click, so you can activate it when uploading files overnight, or any other circumstance when you won’t be there to control the sleep/screensaver. 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. This free software for Mac OS X was originally created by Lighthead Software. Caffeine for Mac is included in System Tools.

- Caffeine Mac app is very popular and useful app. I recently change my 2010 mid MBP to 2015 NEW MBP. And the original Caffeine menubar icons really annoyed me. Because of non retina, and old fashioned shapes of icons. There are many good icons to use, but I wanna use the app with my own design. The shape is inspired from coffee server.
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. 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. Caffeine will be active only in hours with an x
Compatibility
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.
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.Video
Caffeine user humancar2n has put together a short YouTube video showing how the app works.

How did potentially unwanted applications install on my computer?In some cases, potentially unwanted apps can be downloaded from supposedly 'official download websites', however, users often download/install them through the set-ups of other (usually free) software. Our security researchers recommend using Malwarebytes.To use full-featured product, you have to purchase a license for Malwarebytes. 14 days free trial available.There are many other apps that people download and install unintentionally including, for example, and. Generally, these programs are advertised as legitimate, useful, and so on. I.e., when developers use the 'bundling' method and present PUAs as extra 'offers'. Uninstall avg mac when not listed in apps. In fact, they do not function as promised and provide no real value.
