Quick Tip: caffeinate your Terminal
Quick tips are random posts regarding something I discovered on my way to something bigger. They usually get longer than “quick” would imply, for which I refuse to apologize.
Another random OS X command line exposé…
There’s a command called that does exactly what the app Caffeine does — keep your computer from sleeping — but it lets you do it from scripts and the command line.
This command can be run in a couple of ways. First, you can add a timer and tell it to prevent sleep for a certain duration. Alternatively, you can attach it to another command to keep the computer awake as long as that process is running, allowing the system to sleep after the command finishes.
It handles different aspects of system sleep: display sleep, idle sleep, disk sleep and “system sleep.” It’s also handy to know that it can wake up your display through a script or SSH session.
You can see the man page for a full list of options, but here are a couple of examples:
Keep your computer awake for 1 hour:
The argument is based on seconds, so an hour is 60 * 60 (3600). Note that you can still sleep your computer manually when caffeinate is running.
In case you’re unfamiliar, the ampersand at the end causes the command to run in the background, freeing up your command line. If you’re running it from something like an AppleScript or Automator, this won’t help. Your script or workflow will keep running until the timer ends. Depending on how you trigger it, that might not be a big deal. In LaunchBar you, you can activate it with Option-Return instead of just Return and it will run the whole script in the background. I’m not sure how Alfred or others handle this.
Keep your computer from idling until a Terminal command finishes
prevents “idle sleeping.” Other options include:
- just prevents the display from sleeping
- just prevents disks from sleeping when idle
- keeps the whole system awake
Wake up your computer
replicates user activity. It causes the same reaction as moving a mouse or hitting a key after your Mac sleeps. Without a argument to set a timeout, it’s supposed to default to 5 seconds, but it seems to hang around a lot longer than that on my system. A single second of user activity is all it takes to wake a machine.
If you need to wake up a monitor from another machine and have a keyless login set up, you can run from a script or the command line to give it a wakeup call. Or keep it awake for a period of time with
That’s really all there is to it. Just another semi-hidden OS X-only command that you might have missed.

Accessibility Permission Prompt
Several users have reported an issue where Caffeine continues to prompt for macOS accessibility permission even after it has been granted.
We are investigating the cause of this issue, it is possible that a change has occured in a recent macOS Catalina update.
If you are experiencing this issue, please follow the steps outlined in the Support Center to ensure that there is not another cause, such as having multiple copies of Caffeine installed, which can cause similar symptoms when upgrading from an older version.
Caffeine is a tiny program that puts an icon in the right side of your menu bar. Click it to prevent your Mac from automatically going to sleep, dimming the screen or starting screen savers. Click it again to go back. Right-click (or ⌘-click) the icon to show the menu.
Originally developed by Tomas Franzén of Lighthead Software in 2006, Caffeine is a well known and loved utility for many Mac users, and its simplicity has allowed it to continue working perfectly long after active development ceased.
Unfortunately for many users, Caffeine began experiencing problems with the release of macOS Mojave, due to the enhanced privacy controls introduced which prevent Caffeine from functioning correctly.
We reached out to Tomas to inquire if we could continue development of Caffeine, as we believe it fits nicely with our vision of software that is simple, flexible and powerful.
Tomas has graciously provided the source code under an open source license, allowing us to continue developing Caffeine where he left off.
Genuinely useful, lean and simple to use. It even has a cute icon.

Pros
Simple
As Expected
Cute icon
Convenient
Cons
No cons I can think of.
Summary
Whenever I know I'm going to be on the laptop for a school paper or a long work assignment, it gets really frustrating when my screen dims all the time but I don't want to have to change the display settings all the time. When I got this, my problem was solved! The screen stays lit for however long the icon is on. Plus the icon makes me think of drinking coffee, which psychologically works to wake me up. Love it!

Pros
This is a useful app that has a great design and is very easy to use.
Cons
Only thing is that it doesn't stop your mac from sleeping when you close it.
Summary
Caffeine is an incredibly useful app that does the job it's supposed to do. It's simple, effective, and best of all, it's free! The coffee cup in the menu bar is perfect and it's a great indicator of signifying whether the app is on or off. It's especially useful when you want to keep your computer running for overnight work.

Pros
It's there when you need it and all but invisible when you don't. One click on the icon in the menu bar turns it on/off.
Cons
At first I was reluctant to have an app running in the background all the time, however it does not seem to have had any impact on performance.
Summary
Get it.

Pros
This neat little program does one thing only and it does it very well. It keeps my screen from going to sleep. I use it during video conferencing when I'm not actively doing things that keep my screen awake.
Cons
None at all.
