您可能已经注意到，一旦您停止与 Mac 进行积极交互，您的Mac就会很快进入睡眠状态。即使您不是打算在计算机上完成工作，如果Mac检测到您没有使用它，它也会在您身上睡着。当您仅使用电池供电时，情况会变得更糟。
发生这种情况是因为您的Mac正在利用它所拥有的一切机会来节省能源和延长电池寿命(save battery life)。虽然这听起来像是一件好事，但它可能会很烦人，例如当您的Mac决定在您下载某些内容时进入睡眠模式并且您必须重新开始时。
幸运的是，有几种方法可以阻止计算机上的睡眠模式并防止Mac进入睡眠状态。
为什么要在 Mac 上阻止睡眠模式(Why Block Sleep Mode on Your Mac)
您可能想要阻止 Mac 的省电模式的一个明显原因是它是否开始中断活动任务。例如，您开始下载并进入睡眠状态，期望醒来完成下载。相反，您的 Mac 会与您同时进入 睡眠状态，并且下载会被取消。

How to Prevent Your Mac From Sleeping
You might have noticеd that your Mac falls asleep quіte fast as soon you stop actively interacting with it. Even if you didn’t mean to finish working on your compυtеr, yоur Mac can fall asleep on you if it detects that you’re not using it. It getѕ even worsе when you’re running it on battery power only.
That happens because your Mac is using every chance it has to preserve energy and save battery life. While that sounds like a good thing, it can be rather annoying, like when your Mac decides to go into sleep mode while you’re downloading something and you have to start all over again.
Luckily, there are a couple of ways to block the sleep mode on your computer and prevent your Mac from sleeping.
Why Block Sleep Mode on Your Mac
One obvious reason why you might want to block your Mac’s power-saving mode is if it starts interrupting active tasks. For example, you start a download and go to sleep expecting to wake up to a finished download. Instead, your Mac falls asleep at the same time as you do and the download’s canceled.
Another occasion could be when you leave your computer for just a few minutes, expecting to come back and continue working straight away. Instead, you come back to your Mac in sleep mode and have to interrupt your schedule to bring it back to life.
Whatever your reason may be, it’s always useful to know a few tricks to stop your computer from sleeping.
How to Prevent Your Mac From Sleeping
There are a few different methods you can use to temporarily stop your Mac from sleeping. If you’re looking for more functionality, download a utility or a third-party app that will allow you to control your Mac’s sleep mode better. If you don’t want to bother installing new software, try one of the following built-in methods.
Use Mac’s Energy Saver
Energy Saver is a built-in tool on your Mac that you can use to customize your computer’s sleep mode.
Using Energy Saver, you can set the exact time when your computer goes to sleep after you stop using it, both on battery and when using a power adapter. You can set the time for as soon as 1min, to 3hrs, to Never. The latter means disabling your computer’s automatic sleep mode completely.
The best part of Energy Saver is a function called Power Nap. When Power Nap is enabled, your Mac can automatically backup using Time Machine, as well as check for new email and calendar alerts while sleeping. If you’re connected to a power adapter, your Mac can also turn off the screen without activating sleep mode.
To access Energy Saver, go to your System Preferences > Energy Saver.
You’ll also find it in the drop-down menu under the battery icon in the upper-right corner of your screen.
If you just want to set your Mac to sleep and wake up at a certain hour, select Schedule at the bottom of the Energy Saver window and set the times.
Use the Terminal Command
If you don’t find Mac’s Energy Saver efficient, you can use Terminal as an alarm clock for your computer to solve the sleep mode problem.
To open Terminal, go to Applications > Utilities folder. Alternatively, use the keyboard shortcut Cmd (Command) + Space and search for Terminal in Spotlight.
Once you open the Terminal window, type caffeinate into it and press Enter. This will keep your Mac awake as long as you have that Terminal window open. You can minimize or hide it, and that won’t affect your Mac’s blocked sleep mode.
To turn sleep mode back on, either Quit Terminal or use the keyboard shortcut Ctrl + C to terminate the command.
If you’re looking for more control over your Mac’s sleep mode, try a Mac app called Amphetamine. You can download it for free from the App Store. It will then appear as a little pill icon in the upper-right corner of your screen.
You can later customize the icon to look like an owl, anything coffee-related, sun and moon, emoji, and even your own custom image.
The app’s menu is pretty straightforward and easy to navigate. On top of the standard keep-awake functionality, Amphetamine offers you to control your Mac’s sleep mode using various triggers.
For example, your computer won’t go to sleep while an app is running or a file is downloading. You can set up a whole panel of custom Triggers to take full control over your Mac’s sleep mode.
The Caffeine app is truly “old but gold”. It’s a free, simple anti-sleep app that’s been around for years.
To activate Caffeine on your Mac, download it and move it to your Applications.
Next, the app will ask you to give permission to control your computer.
After you do that, all you need is to press the coffee cup icon that will appear in your Mac’s ribbon menu on top of the screen. Press the cup icon again to disable it. The beauty of this app is its simplicity.
Additionally, you can set Caffeine to automatically activate at lunch or at login. The duration also varies from as little as 5min to Indefinitely.
Learn to Control Your Mac’s Sleep Mode
When experimenting with your Mac’s sleep mode, make sure to pay attention to which settings you’re changing and which utilities you’re using. Otherwise, you might find yourself searching for a way to put your Mac to sleep the next time.
