macOS 以低维护、快速且可靠的操作系统而闻名。根据我们的经验，这在很大程度上是正确的。然而，即使是强大的 macOS 也可能成为堵塞管道的累积数字垃圾的受害者。
这就是为什么有多种付费和免费实用程序适用于 Apple 的计算机系列，它们承诺为您的Mac提供良好的擦洗效果。我们决定尝试流行的应用程序，例如CleanMyMac和CCleaner for Mac，看看这些实用程序是否有任何真正的好处。
CleanMyMacX是一个付费软件包，它提供一长串好处以及一些关于性能提升的大胆声明。
CleanMyMacX具有三个主要组件。有系统文件清理部分，它寻找孤立和冗余数据，让你删除它。这甚至包括与您不相关的深度嵌入的内容，例如本地化数据。
该应用程序的第二部分是反恶意软件扫描程序。由于Mac(Macs)没有病毒的长期神话，许多读者可能会感到惊讶。事实是，保护Apple(Apple)计算机免受病毒、木马、蠕虫和其他数字恶意软件侵害的唯一因素就是默默无闻。随着用户群的快速增长，恶意软件制造商现在值得花时间瞄准这些机器，因此拥有扫描仪并不是最糟糕的想法。
软件包的最后一部分是性能增强、监控和调整。
MacPaw提出的具体要求是，根据他们对 2016 MacBook Pro 15的测试，您将获得 4 倍的启动速度、2.5 倍的响应速度和 5 倍的可用空间。对于我们的 2019 款MacBook Pro 13，很难说性能方面发生了任何变化。它已经在闪存中启动并且重新启动在现代计算机上是如此罕见，几乎没有任何区别。
我们要说的是CleanMyMacX非常全面，它以一种巧妙的方式集中管理您的系统，并在我们狭窄的 128GB (CleanMyMacX)MacBook Pro上回收了大量可用空间。所以，在我们看来，这笔钱是物有所值的。

概括
尽管该程序不是免费的，但它已经存在了很长时间并且拥有良好的记录。总体而言，如果您更喜欢在不重新格式化的情况下清理Mac ，我们建议您使用它。
恒星加速 Mac(Stellar Speedup Mac)
Speedup Mac是另一个付费套餐，但您可以在购买前免费试用。与CleanMyMac X不同，Speedup不提供任何反恶意软件功能。它所承诺的是，您将拥有更多可用空间和更快的Mac。
它有多种方法来实现这一目标。其中包括查找重复文件、识别您可能不知道的大文件以及分析您不使用的启动和第三方应用程序。它还针对未使用的语言文件、Mac垃圾文件和其他类似的零散碎片。
这一切听起来都不错，但是在注册免费试用版、放弃我们的信用卡信息并下载通过电子邮件发送给我们的链接中的应用程序后，我们收到了一条错误消息。该应用程序需要更新才能与最新版本的 macOS Catalina一起使用。所以我们别无选择，只能取消试用并继续前进。
优点
缺点
- 该应用程序不会安装在 macOS Catalina上。
- 一次性购买没有选择。

CCleaner是一款流行且值得信赖的系统清理器应用程序，它在Windows方面很受欢迎，但很多人可能会惊讶地发现它还有Mac版本。我们只在这里查看免费版本，作为我们迄今为止查看的付费应用程序的替代品。
免费的Mac版 CCleaner(CCleaner)专注于两件事。第一个是让你的电脑更快，第二个是隐私保护。付费版本增加了实时监控、自动更新和高级支持。
我们喜欢这个小应用程序，它的工作原理和宣传的一样。与Clean My Mac X(Clean My Mac X)相比，免费版本的功能较少，但对于想要一个好的免费解决方案的普通Mac用户，或者对于运行满是Mac(Macs)的实验室的学校来说，没有比这更好的了。
优点
缺点
- 不是特别吸引人。
- 道路中间(Middle)的用户友好性。

应用清理器(AppCleaner)
到目前为止，我们看到的所有应用程序都包含多种功能，试图通过提供真正的优化噱头来吸引您，因此我们认为像AppCleaner这样的应用程序可能是一个简单的替代方案。这个小小程序只做一件事，而且只做一件事；它会正确卸载应用程序。
它的工作方式非常简单，至少从用户的角度来看是这样。只需(Simply)将您不再需要的应用程序拖到AppCleaner 中(AppCleaner)，它就会在您的硬盘驱动器中找到并列出与该应用程序关联的所有文件。然后，在查看这些文件后，您只需单击一个按钮即可将它们全部删除。
这里的主要缺点是，对于已经被删除并在您的计算机上留下残渣的应用程序几乎没有帮助。但是，它帮助我们删除了我们曾尝试卸载但其图标仍然在Launchpad上杂乱无章的应用程序。现在他们走了，只需要点击一两下。

清洁应用程序(Cleaning Apps Do Anything)对Mac 有用(Mac)吗？
这是一个很难回答的问题，因为您的计算机在日常桌面任务中的表现可能非常主观。这些清理应用程序不太可能在基准测试中产生太大影响，在固态存储(solid-state storage)时代，实际数据的混乱程度并不重要，因为它可以立即从任何位置读取。
这些清洁应用程序的效用在哪里？好吧，他们帮助的一个主要领域是释放磁盘空间。尤其是现代MacBook(MacBooks)的系统驱动器非常小。128GB 和 256GB 磁盘并不少见，这意味着您可能很快就会用完磁盘空间。更糟糕的是，在MacOS中消耗空间的情况并不总是很明显。
从这个角度来看，我们真的可以推荐这些垃圾清理应用程序作为删除通常不需要的文件的快速方便的方法。您可以手动完成，但这需要很长时间，并且需要精确了解在哪里查看。
像CleanMyMac或CCleaner这样的应用程序安全吗？没有完全安全的应用程序这样的东西，因此这些应用程序总是有可能删除重要的东西或以其他方式干扰Mac的正常运行。这就是为什么您应该始终使用 Time Machine(backup using Time Machine)或您选择的备份软件来维护最近的备份。
CleanMyMac X Review: Is It the Best Cleaning App for MacOS?
macOS has a reputation for being a low-maintenancе, snаppy, and reliable operating system. In our experience, that’s largely truе. However, even mighty macOS cаn fall victim to accumulated digital junk clogging up its pipes.
This is why there are several paid and free utilities for Apple’s line of computers that promise to give your Mac a good scrubbing. We decided to try popular apps such as CleanMyMac and CCleaner for Mac to see if there’s any real benefit to these utilities.
CleanMyMacX is a paid package that offers a long list of benefits as well as a few pretty bold claims about performance increases.
CleanMyMacX has three main components. There’s the system file cleaning part, which looks for orphaned and redundant data, letting you delete it. This even includes deeply-embedded stuff such as localization data that’s not relevant to you.
The second part of the application is an anti-malware scanner. Many readers might find this surprising thanks to the persistent myth that Macs don’t have viruses. The truth is that the only thing that protected Apple computers from viruses, trojans, worms, and other digital nasties was obscurity. With a rapidly growing user base, it’s now worth the time of malware makers to target these machines, so having a scanner isn’t the worst of ideas.
The final part of the package is performance enhancement, monitoring, and tweaking.
The specific claims made by MacPaw are that you’ll get 4x faster boots, 2.5x more responsive apps, and 5x the amount of free space you’d otherwise have, based on their testing with a 2016 MacBook Pro 15. With our 2019 MacBook Pro 13, it’s hard to say that anything has changed performance-wise. It already booted up in a flash and rebooting is such a rare occurrence on modern computers it hardly makes any difference.
What we will say is that CleanMyMacX is utterly comprehensive, it centralizes management of your system in a slick way and it recovered a significant chunk of free space on our cramped 128GB MacBook Pro. So, it’s well worth the money in our opinion.

Summary
Though the program is not free, it’s been around for a long time and has a good track record. Overall, we recommend using it if you prefer cleaning up your Mac without reformatting.
Speedup Mac is another paid package, but you can try it for free before buying. Unlike CleanMyMac X, Speedup doesn’t offer any anti-malware functionality. What it does promise is that you’ll have more free space and a faster Mac.
It has various ways to achieve that goal. These include looking for duplicate files, identifying large files you might not know about, and analyzing which startup and third-party apps you don’t use. It also targets unused language files, Mac trash files, and other similar loose bits and pieces.
This all sounds pretty good, but after signing up for the free trial, giving up our credit card information, and downloading the application in the link sent to us via email, we were hit with an error message. The application needs to be updated to work with the latest version of macOS Catalina. So we had no choice but to cancel the trial and move on.
Pros
Cons
- The application wouldn’t install on macOS Catalina.
- No option for a once-off purchase.

CCleaner is a popular and trusted system cleaner app on the Windows side of the fence, but many people may be surprised to know that there’s also a Mac version. We’re only looking at the free version here as an alternative to the paid applications we’ve looked at so far.
The free CCleaner for Mac focuses on two things. The first is to make your computer faster and the second is privacy protection. The paid version adds real-time monitoring, automatic updates, and premium support.
We loved this little app and it worked just as advertised. The free version is light on features compared to something like Clean My Mac X, but for the average Mac user who wants a good free solution or perhaps for schools that run labs full of Macs, it doesn’t get better than this.
Pros
- It’s free.
- It works just fine.
Cons
- Not particularly attractive.
- Middle of the road user-friendliness.

All of the apps we’ve looked at so far are packed with multiple features, trying to attract you by offering a veritable buffet of optimization gimmicks, so we thought that something like AppCleaner could be a simple alternative. This little applet does one thing and one thing only; it uninstalls applications properly.
The way it works is dead simple, at least from the user’s perspective. Simply drag an app you no longer want into AppCleaner and it will find and list all the files associated with the app across your hard drive. Then, after reviewing those files, you simply click a button to delete them all.
The main downside here is that it’s of little help for apps that have already been removed and left their crud all over your computer. However, it helped us remove apps that we had tried to uninstall but still had their icons cluttering up Launchpad. Now they’re gone and all it took was a click or two.
Pros
- It does one thing and it does it well!
- It’s free!
Cons
- It only does one thing, but again it does it well!

Do Cleaning Apps Do Anything For a Mac?
This is a very difficult question to answer because your computer’s performance in day-to-day desktop tasks can be very subjective. These cleaning apps are unlikely to make much difference in benchmarks and in the age of solid-state storage it doesn’t matter how jumbled up the actual data is, since it can be read from any location instantly.
Where does that leave the utility of these cleaning applications? Well, one major area where they help is in freeing up disk space. Modern MacBooks in particular have pretty tiny system drives.128GB and 256GB disks aren’t uncommon, which means you could run out of disk space pretty quickly. What’s worse, it’s not always obvious in MacOS where that space is being consumed.
From that point of view, we really can recommend these junk cleaning apps as a fast and convenient way to remove typically unneeded files. You could do it manually, but that would take ages and require precise knowledge of where to look.
Is an application like CleanMyMac or CCleaner safe? There is no such thing as a perfectly safe application, so there’s always the chance that these apps will delete something important or otherwise interfere with the normal functioning of your Mac. This is why you should always maintain a recent backup using Time Machine or the backup software of your choice.
