每个人都知道在长时间工作后触摸笔记本电脑的感觉，只是感觉它更像一座活火山，而不是一个精致的工具。MacBook 可能特别容易出现这个问题，但好消息是有办法在这个问题开始之前阻止它。
过热的MacBook会影响性能，导致机器运行速度变慢，甚至可能损坏电池并降低其整体容量。不要等到您的计算机变得太热而无法触摸时，采取主动措施来防止MacBook过热。
如何阻止 MacBook 过热(How to Stop a MacBook From Overheating)
如果您的MacBook容易过热，请确保您没有犯这些常见错误。
允许适当的通风(Allow Proper Ventilation)
每个人都看过有人躺在床上使用MacBook的新闻图片。虽然躺在床上浏览社交媒体当然很放松，但这并不总是最明智的举动——尤其是在粉丝被屏蔽的情况下。
MacBook系列笔记本电脑往往只有一个冷却风扇，没有同等的 Windows 笔记本电脑那么多的通风(Windows)。这会导致更高的温度，但如果没有适当的通风，您的笔记本电脑可能会发热更多。确保它在水平面上，并且没有任何东西阻挡通风口。
确保您的粉丝也处于正常工作状态(proper working order)。如果听起来风扇不转或您感觉不到气流，则可能是风扇堵塞或控制器损坏。
清理你的 Mac(Clean Your Mac)
与允许适当通风一样，您希望Mac 尽可能保持清洁(keep your Mac as clean as possible)。随着笔记本电脑上的灰尘和污垢堆积，它有时会阻塞MacBook内的气流并阻止其正常冷却。
通过每周至少使用一次电子清洁湿巾，您可以消除任何可能阻碍机器流动的东西。
更新软件(Update Software)
macOS 更新是每年一次的更新，带来更新的界面。您的 macOS 更新是您将对 PC 进行的最重要的修改之一，它会带来新的功能、安全补丁和性能优化。
过时的 MacBook 可能更容易过热。如果Apple技术人员发现代码中存在可能导致问题的故障，将发布更新来修复它。如果不进行这些更新，您的系统就会面临威胁和漏洞。
要更新您的 macOS 软件，请打开设置(Settings )>软件更新(Software Update)。它会自动检查任何可用的更新并提示您是否有可用的更新。
检查 Mac 活动(Check Mac Activity)
活动监视器(Activity Monitor)可让您查看计算机上所有当前活动的程序，以及使用最多资源的程序。如果您的CPU负担过重，关闭最密集的程序可以释放资源。
键入Command + Space打开 Spotlight，然后键入Activity Monitor并按Enter。这将打开活动监视器(Activity Monitor)并在前台和后台显示每个正在运行的程序。单击顶部的% CPUCPU功率的程序进行排序。
如果有任何您不认识的程序，请对它们进行一些研究，以确保它不是 rootkit 或恶意软件或其他一些不太令人愉快的应用程序。如果它不是必要的应用程序或您当前正在使用的应用程序，请结束该过程。CPU上的负载越少，机器过热的可能性就越小。
关闭浏览器选项卡(Shut Down Browser Tabs)
您打开的每个浏览器选项卡都需要一定数量的系统资源——尤其是 Chrome(especially Chrome)，这是一个臭名昭著的违规者，因为它使用了荒谬的电量。如果可能，请避免使用Chrome并坚持使用对资源更友好的浏览器，例如Safari或Firefox。
虽然人们打开 20 个不同的浏览器标签并让它们保持打开状态可能是一种迷因，但您不应该这样做。如果您打开了不再需要的浏览器选项卡，请将其关闭。您的机器不仅运行得更快，而且有助于防止MacBook过热。
使用官方充电器(Use Official Chargers)
如果您丢失了MacBook充电器，您可能会想购买一个成本更低的充电器；毕竟官方充电器要80多美元。抵制这种诱惑。市场上的非官方充电器不如官方充电器可靠。此外，它们最终可能会损坏您的电池。
笔记本电脑电池损坏不仅会缩短电池寿命。电池过热有时会爆炸并严重伤害用户。仅使用(Use)值得信赖的充电器，以确保不会损坏MacBook或您自己。
更换电池(Replace Your Battery)
如果您的MacBook 电池太旧(MacBook battery is too old)，它可能会在使用或充电时开始发热。如果是这种情况，唯一真正的解决办法是用更新的版本更换电池。您可以通过 eBay 或Apple(Apple)官方网站找到要购买的电池。
您可以长时间使用旧电池；事实上，MacBook(MacBooks)有一个内置的电池分析工具。虽然您可以在家更换电池，但我们不建议您这样做。通常最好由授权维修店进行修复，尤其是在您的MacBook在保修范围内的情况下。您可以在他们的网站上查看Apple 更换 Mac 电池的价格。(replace a Mac battery by Apple)
检查恶意软件(Check For Malware)
尽管这种情况并不常见，但Mac计算机可能并且确实会不时感染病毒和恶意软件。系统有不受欢迎的客人搭便车的最大迹象之一就是过热。如果您的MacBook持续升温，请为您的MacBook寻找防病毒软件。
通常最简单的解决方法是删除有问题的软件，以将您的系统恢复到完整的工作状态。避免(Avoid)点击可疑链接或访问具有潜在危险的网站，以免恶意软件进入您的计算机。为 Mac找到您信任的防病毒软件(antivirus software you trust for Mac)并执行定期扫描。
MacBook 过热的原因有很多。好消息是它们中的大多数并不危险。只需(Just)注意让您的笔记本电脑获得所需的适当通风，并且可能需要更少的CPU。
How to Stop a Macbook from Overheating
Everyone knows the sensation of touching their laptop after a long work session, only for it to feel closer tо an aсtive volcano than a delicate tool. MacBooks can be particularly prone to this problem, but the good news is there are ways to stop this problem before it starts.
An overheating MacBook can impact performance, cause your machine to run more slowly, and can even potentially damage your battery and reduce its overall capacity. Don’t wait until your computer becomes too hot to touch—take proactive steps to stop your MacBook from overheating.
How to Stop a MacBook From Overheating
If your MacBook tends to overheat, make sure you aren’t making these common mistakes.
Allow Proper Ventilation
Everyone has seen the press images of someone laying in bed using their MacBook. While it’s certainly relaxing to lay in bed and browse social media, it’s not always the smartest move—especially if the fans are blocked.
The MacBook series of laptops tend to have only a single cooling fan without as much ventilation as an equivalent Windows laptop. This results in higher temperatures, but without the right ventilation your laptop can heat up even more. Ensure it’s on a level surface and nothing is blocking the vents.
Ensure your fans are in proper working order, too. If it sounds like a fan isn’t spinning or you can’t feel airflow, a fan might be blocked or the controller might be broken.
Clean Your Mac
In the same vein as allowing proper ventilation, you want to keep your Mac as clean as possible. As dust and grime build up on your laptop, it can sometimes block airflow within the MacBook and stop it from cooling properly.
By using electronic cleaning wipes at least once per week, you can eliminate anything that might have blocked the flow through the machine.
Update Software
macOS updates are more than yearly changes that bring an updated interface. Your macOS update is one of the most important modifications you’ll make to your PC and brings along with it new features, security patches, and performance optimization.
An out-of-date MacBook may be more prone to overheating. If Apple technicians discover a glitch in the code that could cause problems, an update will be released to fix it. Without making these updates, you leave your system open to threats and vulnerabilities.
To update your macOS software, open Settings > Software Update. It will automatically check for any available updates and prompt you if one is available.
Check Mac Activity
The Activity Monitor lets you see all currently active programs on your machine, as well as those that are using the most resources. If your CPU is overtaxed, closing the most intensive programs can free up resources.
Type Command + Space to open Spotlight, and then type Activity Monitor and press Enter. This opens the Activity Monitor and displays every running program in both the foreground and the background. Click the % CPU icon at the top to sort by programs using the most CPU power.
If there are any programs that you don’t recognize, do a bit of research on them to make sure it isn’t a rootkit or malware or some other less-than-pleasant application. If it isn’t a necessary application or one you’re currently using, end the process. The less load you place on your CPU, the less likely your machine is to overheat.
Shut Down Browser Tabs
Every browser tab you have open demands a certain amount of your system resources—especially Chrome, a notorious offender for using a ridiculous amount of power. If possible, avoid Chrome and stick to more resource-friendly browsers like Safari or Firefox.
While it might be a meme that people open 20 different browser tabs and leave them open, you shouldn’t do that. If you have browser tabs open that you no longer need, shut them down. Not only will your machine run that much faster, but it will help stop your MacBook from overheating.
Use Official Chargers
If you lose your MacBook charger, you might be tempted to invest in a lower-cost one; after all, the official charger costs more than $80. Resist this temptation. The unofficial chargers on the market are not as reliable as the official ones. In addition, they can end up causing damage to your battery.
Damage to a laptop battery can cause more than shortened battery life. Overheating batteries can sometimes explode and seriously injure the user. Use only trusted chargers to ensure you cause no damage to your MacBook or yourself.
Replace Your Battery
If your MacBook battery is too old, it might begin to heat up while in use or when charging. If this is the case, the only real fix is to replace the battery with a newer version. You can find batteries for purchase through eBay, or on the official Apple website.
You can use an older battery for a long time; in fact, MacBooks have a built-in battery analysis tool. While you can replace the battery at home, we don’t recommend it. It’s often better to have an authorized repair shop to handle the fix, especially if your MacBook is covered under warranty. You can see the prices to replace a Mac battery by Apple on their website.
Check For Malware
While it’s uncommon, Mac computers can and do get infected with viruses and malware from time to time. One of the biggest signs that your system has an unwanted guest hitching a ride is overheating. If your MacBook is consistently warming up, look for antivirus software for your MacBook.
Often the easiest fix is to remove the offending software to restore your system to full working order. Avoid clicking shady links or visiting potentially dangerous websites so that no malware can come onboard your computer. Find an antivirus software you trust for Mac and perform regular scans.
There are many reasons your MacBook might overheat. The good news is that most of them aren’t dangerous. Just take care to let your laptop get the proper ventilation it needs, and maybe demand a little bit less of your CPU.
