Prevent App Nap & Sleep on Mac OS X, by david When Mac OS X Mavericks was released, it introduced a special feature called App Nap that helps improve battery life of your Mac by automatically slowing down or freezing apps that are running in the background.
Hello, dear Mac users! I'm glad to see you here again and I'm going to tell you some useful tips on controlling the sleep functions of your Mac. Macs are believed to be power efficient thanks to their optimized schedule of sleeping on OS X. Still, in some situations you won't want your machine to sleep, for example, while downloading some large file, reviewing a spreadsheet, reading a book or analyzing content from the screen. I can continue this list nearly forever. To cope with this issue, visit ' System Preferences' and play with your settings.
But this can become a problem, if you need to do this too often. So, I want to tell you about different comfortable ways of dealing with this dilemma! A classic and the first option that comes to mind is a free Caffeine program. Recent OS X versions made some changes to the sleeping mode, and there is a comfortable built-in app for inducing insomnia.
The Caffeinate aptly is a utility looking like a command line and can be accessed with Terminal. As you could already suggest, you should run a command there and your Mac won't get asleep until you turn it off. It can be run in a classic way or be modified and customized basing on your preferences and needs. You can add a timer, target a process or program, or modify some specific sleep options. By the way, I have recently found a cool app for Mac called Setapp, subscription to which allows me to save money and popular Mac apps. (Setapp it’s free for Download).
Launch Terminal As I've said before, Caffeinate can be accessed via Terminal. Find it in the Spotlight search, or Launchpad, or ' Applications' ' Utilities', and open it.
Run the command 'Caffeinate' Once you run this command in Terminal, you Mac will be prevented from going asleep. It will be active all the time while Terminal is active. Type in: ' caffeinate' inside your Terminal and press Enter.
Terminal will show you 2 small actions that can tell you that it is active now. The red spotlight highlighted with a dot and a red arrow tells us that Terminal is running some command at the moment. And an unavailable cursor indicated by a blue arrow tells us that that command is being carried out currently.
How to stop it If you need to stop Caffeinate, press Ctrl+C keyboard keys while you are using Terminal. Maybe you already know that it is a classic combination that stops the current commands in Terminal.
So, your Mac will restore its usual sleep cycle after you press this key combination. As I've noted before, the command of Caffeinate can work by itself or with some modifiers.
Here are several useful ones: Adding a timer Let's pretend that you need your Mac to run some process for about an hour and then it would get back to its usual cycle. Modify the Caffeinate command: caffeinate -t 3600. ' -t' - adds a times. ' 3600' - is the amount of seconds you need. Choosing a certain app/process Another modifier type is attaching Caffeinate to an app or some system process.
The main benefit of doing that is the fact that your system won't fall asleep while a certain process or application is running. For instance, if you want to choose Final Cut Pro as such app, modify the command the following way:.
‘ caffeinate /Applications/Final Cut ‘. ‘ Pro.app/Contents/MacOS/Final Cut Pro’ It is much simpler than it can seem at the start. So, the first part was just the ' caffeinate' command, and as for the second one, it was a location of a program of your choice. In our case, it was Final Cut Pro. More specific modifier flags for Caffeinate Here are few other useful options you can use in your everyday work with the app:.d is for preventing Mac's display from falling asleep.i can prevent OS X from idle sleeping.m is for preventing the disk from falling asleep.s can prevent Mac from going to sleep while it is plugged in.u replicates an active Mac user at the moment Surely, all these options can be chosen for different scenarios. For instance, if you want to watch some series on Netflix and take a sleep after it, combine that pieces in one command: caffeinate -d /Applications/Firefox.app/Contents/MacOS/firefox-bin Benefits and limitations of Caffeinate If you have experience of using the command line, then you surely know how to combine commands to get a right result.
I have shown just a few variants in my article, but you can create new scenarios and vary them from time to time. On the other hand, there are lots of variants that will conflict with each other, and you can make mistakes in case you are not an expert in using Terminal, especially if you have never used it before. In this situation, it is better to use the Caffeine application that is intuitive and user-friendly. As for me, I can work with both options. Caffeine is a perfect way for quick and easy solutions, but Caffeinate is an ideal option for creating your personal scenarios.

Hope to see you again in my blog soon!;).
SmartSleep Sleep your Mac differently depending on the battery level. Your MacBook or MacBook Pro knows the following sleep states:.
sleep machine will go to sleep only (saves state in RAM only, battery keeps RAM contents). hibernate only machine will go to hibernate only. (saves state on disk, battery will not be used). sleep & hibernate machine sleeps and hibernates. (default) Just sleep means that the notebook will go to sleep fast, but you lose the ability to change the battery as the battery is needed to keep the contents of the memory (RAM).
Just sleep and hibernate will wake the computer fast, but sleeping will take ages as the contents of the memory are saved to disk before entering the sleep. The solution SmartSleep lets you select each sleep state. Additionally the new SmartSleep state lets your notebook just sleep while the battery has a high level. If the battery level drops below a certain point (default is less then 20% or 20 minutes) it will switch to sleep and hibernate. So you have the best of both worlds. Furthermore it will expand the lifetime of your SSD (if you have one) as your MacBook won't write a hibernate file as often.
Features. QuickSleep feature New - sleep your Mac immediately the way you want. SmartSleep Menu Item New - figure out the current Sleep State and QuickSleep. Insomnia feature in Menu Item New to keep your Mac awake. Timed insomnia. Keep your Mac awake only for a time.
Five different sleep modes to chose from: - system default - smart sleep (if your Mac has a battery ) - sleep only - hibernate only - sleep and hibernate. Does not need admin privileges New. Runs as a application not a preference pane New. Beeps when closing the lid, so you don’t forget that you have insomnia enabled (plugin). Requirement: Mac OS X 10.6.6 and higher, 10.7 - 10.10. For Mac OS X 10.6 download Clamshell Insomnia plugin Beginning with version 3.06 SmartSleep now supports the SmartSleepInsomnia Plugin.
As soon as you install this plugin, the Insomnia mode will keep your Mac awake even if you close the lid. AppStore users The old AppStore version does not run correctly on lion due to a bug in lion. Apple does not allow me to update the AppStore version as the workaround for the bug requires admin privileges and is therefore not allowed in the AppStore. Instructions for installation are as following: Install the AppStore version. If this fails read the next paragraph.
Run the AppStore version - this will copy the appstore license into your Library folder. Quit the AppStore version. Remove the AppStore version located in /Applications.
Download the Website version. Copy the Website version to /Applications.
Start the Website version. New Application Icon, Uninstalling the old version 2.x Btw. If you remember the old Application icon - That has changed lately. If you are using an old version (prefPane) you need to uninstall the old version before installing the new one.
This is due to some bug in the AppStore installer. Background Back in 2005 a feature called hibernate silently went into newer PowerBooks. With an nv-ram setting it was possible to enable hibernation on old Powerbooks as well. A friend of mine pointed this out to me and having done no Cocoa programming at all on Macs I decided to venture into this realm and write a nice interface to it - Hibernate.prefPane was born. I quickly found out that hibernation wasn’t a feature I wanted and the program lay dormant for two years. When I bought an Intel MacBook Pro I was annoyed by the hibernation feature which just takes too long to get my Mac to sleep.
I updated Hibernate but that was not enough, so I decided to write SmartSleep.
