在性能方面，Mac电脑是野兽。与Windows设备相比，Mac计算机通常也不太容易受到病毒和恶意软件的攻击。因此，安全性也是一流的。然而，与流行的看法相反，macOS 可能会感染各种类型的恶意软件(types of malware)。Malwarebytes 的这份2021 年恶意软件状态报告就是有力(2021 State of Malware report by Malwarebytes)的证明。
恶意软件(Malware)感染并不是导致Mac 性能下降(slow performance in Mac)的唯一罪魁祸首。其他因素包括过时的软件和硬件、缓慢的登录应用程序以及有限的硬盘空间。手动诊断或排除这些问题可能很困难。这就是为什么您应该偶尔使用更清洁的软件扫描您的Mac 。
这些应用程序可以通过删除垃圾文件、重复文件、临时缓存文件和其他冗余大文件来释放Mac上的磁盘空间。一些更干净的应用程序甚至与防病毒工具捆绑在一起，因此您不必安装独立的macOS 防病毒软件(macOS antivirus software)。
本文汇编了一些最好的Mac清理软件，可以帮助您提高设备的性能。
1. AVG 清洁剂(AVG Cleaner)
AVG Technologies开发了这个软件，是流行的AVG防病毒工具的创造者。它在Apple App Store中免费提供，因此它比(Apple App Store)App Store之外的清洁工具相对安全。该界面非常简单且非常易于使用。我们还发现我们的测试 MacBook 上的磁盘扫描速度非常快。
该应用程序的仪表板上有两个选项：磁盘清理器(Disk Cleaner)工具和重复查找器(Duplicate Finder)。磁盘清理器(Disk Cleaner)扫描您的Mac 硬盘驱动器以查找应用程序缓存（临时文件）、垃圾文件、下载文件和日志文件。
另一方面，重复查找器(Duplicate Finder)在特定文件夹中寻找重复文件。令人失望的是，该工具无法扫描您的整个Mac驱动器以查找重复文件——您必须为其分配一个文件夹才能手动扫描。
AVG Cleaner是市场上最好的免费Mac清洁器应用程序之一。它很轻巧，可以完成工作。但是，有更好的（付费）替代方案，具有广泛的磁盘清理和性能优化功能。
2.清洁工(CCleaner)
CCleaner是清洁软件生态系统中家喻户晓的名字。在“工具”部分，您会找到用于卸载不需要的应用程序以及删除大文件和重复文件的实用程序。您可以自定义重复文件查找器以搜索整个磁盘或特定用户文件夹。“大文件查找器”还可以微调以定位大小范围内的应用程序（例如，大于 2GB、500MB 等的文件）。
“清理器”部分是您删除Safari数据、互联网缓存文件、应用程序缓存和其他占用磁盘空间的系统文件的地方。确保在运行清理程序之前使用分析按钮检查(Analyze)CCleaner可以释放多少潜在存储空间。
有趣的是，CCleaner 的清洁功能是免费使用的。但是，您需要升级应用程序（一次性支付 24.95 美元）才能使用智能清洁(Smart Cleaning)、自动浏览器清洁等高级功能。
3.MacCleaner Pro 2(MacCleaner Pro 2)
MacCleaner Pro 2拥有任何清洁软件中最好的用户界面之一。该应用程序在不到 30 秒的时间内扫描了我们的测试Mac ，并针对可能的性能问题、垃圾文件和占用大量磁盘空间的文件提供了一份整齐分类的报告。(Mac)当您打开侧边栏上的“清理(Clean)Mac ”部分时，事情会变得更加有趣。
清理工具由四个清理选项组成，并且在每个选项下显示可用存储空间的预览。
打开“专家模式”以访问更多清理选项，以删除不必要的垃圾文件，如应用程序缓存文件、旧屏幕截图、应用程序日志和浏览器缓存文件。
尽管MacCleaner Pro 2是免费安装的，但新用户仅限于两天试用期，之后您需要支付（44.95 美元）才能继续使用。使用Duplicate Finder(Duplicate Finder)、Memory Cleaner等专业功能也需要付款。
4.应用程序清理和卸载程序(App Cleaner & Uninstaller)
当您使用标准删除方法在 Mac 上卸载应用程序时(uninstall apps on Mac)，它们通常会在您的计算机上留下剩余(Remainder)文件（也称为剩余文件）。(Leftover)这些文件和文件夹通常是隐藏的，它们会占用数千兆字节的磁盘空间。您可以手动清除剩余文件，但这是一个漫长的过程，并不是利用时间的最佳方式。这就是为什么我们建议使用专用卸载程序或应用清理程序从Mac中删除应用。(Mac)
如果您不时从Mac中删除应用程序，App Cleaner & Uninstaller是必备工具。它是MacCleaner Pro 2(MacCleaner Pro 2)中嵌入的卸载工具的独立版本。
App Cleaner和Uninstaller在 10 秒内扫描了我们的测试 MacBook，并提供了应用程序、扩展程序、安装文件和剩余文件占用存储空间的汇总状态。您还可以直接在应用程序中查看和修改Mac 的启动程序。(Mac’s startup programs)
在“剩余文件”部分，App Cleaner & Uninstaller会为从(Uninstaller)Mac中删除的应用程序剩余的所有文件编制索引。这就是应用程序最擅长的：在卸载过程中清理与应用程序关联的文件和文件夹。它不会扫描重复文件或大文件，但它可以很好地消除 macOS 中的剩余文件。
值得一提的是，App Cleaner & Uninstaller也是一款付费应用（19.90 美元）。但是，您可以免费使用该应用程序两天而无需付款。
该软件捆绑了几个有助于提升 Mac 性能的工具。使用MacKeeper，您可以获得以安全为中心的实用程序（防病毒和广告软件清理器）、磁盘清理功能（垃圾清理器、重复查找器）和其他性能优化工具。
一键式智能扫描功能将扫描您的 Mac 系统驱动器以查找安全漏洞、清除不需要的文件、诊断和性能问题。
MacKeeper是一款以订阅模式运行的付费应用程序（价格从每月 5.95 美元起）。但是，免费试用版可让您使用一个月的恶意软件扫描、实时防病毒保护和其他磁盘清理功能。
6.MacBooster _(MacBooster)
启动MacBooster，您会发现九种工具的集合，旨在优化您的Mac。System Junk remover 扫描应用程序缓存文件、损坏的登录项、剩余文件、系统日志文件、iTunes 缓存文件等。应用程序卸载程序也做了彻底的工作。它迅速扫描安装在我们Mac上的应用程序，并显示与应用程序关联的所有首选项文件和支持文件。
如果您的Mac需要几分钟才能启动，请使用Mac Booster 的启动优化(Startup Optimization)工具通过删除不需要的启动或登录项来提高启动速度。有趣(Fun)的事实：Mac Booster在我们的测试(Booster)Mac Book上检测到的启动项比此列表中的其他清洁软件多。
尽管MacBooster是一个基于订阅的应用程序（起价 2.49 美元/月），但我们可以访问试用/免费版本中的所有功能。我们在开发者的网站上找不到任何信息。但是，我们预计免费试用特权将在几天后结束。
这是另一个著名的清洁软件，具有磁盘清洁工具、速度优化选项、恶意软件清除程序、存储管理功能。CleanMyMac是一款全能工具，具有清洁软件应具备的所有功能。这是一款付费应用（39.95 美元/年），但您可以注册免费试用以测试其功能。

到更安全、更快的 Mac
虽然这些清理应用程序可以帮助防止攻击并释放设备的存储空间，但它们也可能为黑客和其他恶意软件铺平道路(pave the way for hackers and other malware)。因此，请确保您只安装信誉良好的应用程序，最好是从App Store安装。同样(Likewise)，在下载或安装之前阅读软件的最新评论。您可能会发现该软件对您的Mac(Mac—if)造成的新攻击或漏洞——如果有的话。
7 Best Mac Cleaner Software Tools You Should Be Using
Performance-wise, Mac computers are beasts. Compared to Windows devicеs, Mac computers are also generally less vulnerable to νirus and malware attacks. So, security is also top-notсh. However, сontrary to popular belief, macOЅ can be infected with various types of malware. This 2021 State of Malware report by Malwarebytes is solid proof.
Malware infection isn’t the only culprit responsible for slow performance in Mac. Other factors are outdated software and hardware, slow login applications, and limited hard drive space. Manually diagnosing or troubleshooting these issues can be difficult. That’s why you should occasionally scan your Mac using cleaner software.
These apps can free up disk space on your Mac by deleting junk files, duplicate files, temporary cache files, and other redundant large files. Some cleaner apps are even bundled with antivirus tools, so you don’t have to install a stand-alone macOS antivirus software.
This article compiles some of the best Mac cleaning software that can help speed up your device’s performance.
AVG Technologies developed this software, the creators of the popular AVG antivirus tool. It is available for free in the Apple App Store, so it’s relatively safer than cleaning tools available outside the App Store. The interface is simplistic and super easy to use. We also found the disk scan speed incredibly swift on our test MacBook.
There are two options on the app’s dashboard: a Disk Cleaner tool and Duplicate Finder. The Disk Cleaner scans your Mac’s hard drive for application cache (temporary files), junk files, downloads, and log files.
The Duplicate Finder, on the other, hunts for duplicate files in specific folders. Disappointedly, the tool cannot scan your entire Mac drive for duplicate files—you’ll have to assign a folder for it to scan manually.
AVG Cleaner is one of the best free Mac cleaner apps in the market. It is lightweight and gets the job done. But, there are better (paid) alternatives with extensive disk cleanup and performance optimization features.
CCleaner is a household name in the cleaning software ecosystem. In the “Tools” section, you’ll find utilities for uninstalling unneeded apps and removing large files & duplicate files. You can customize the duplicate file finder to search the entire disk or specific user folders. The “Large File Finder” can also be finetuned to locate apps within a size range (say, files larger than 2GB, 500MB, etc.).
The “Cleaner” section is where you go to delete Safari data, internet cache files, application cache, and other system files using up disk space. Ensure you use the Analyze button to check how much potential storage CCleaner can free up before running the cleaner.
Interestingly, CCleaner’s cleaning functionalities are free to use. However, you’ll need to upgrade the app (a $24.95 one-time payment) to use advanced features like Smart Cleaning, automatic browser cleaning, etc.
MacCleaner Pro 2 has one of the best user interfaces you’ll find in any cleaning software. The app scanned our test Mac in less than 30 seconds and presented a neatly-categorized report of likely performance issues, junk files, and files occupying significant disk space. Things get more interesting when you open the “Clean up Mac” section on the sidebar.
The cleanup tool consists of four cleanup options, plus it displays a preview of freeable storage space under each option.
Turn on “Expert mode” to access more cleanup options for removing unnecessary junk files like applications cache files, old screenshots, applications logs, and browser cache files.
Although MacCleaner Pro 2 is free to install, new users are restricted to a two-day trial period, after which you’ll need to pay ($44.95) for continued usage. The payment is also required to use pro features like Duplicate Finder, Memory Cleaner, etc.
When you uninstall apps on Mac using the standard deletion method, they usually leave Remainder files (also called Leftover files) on your computer. These files and folders are often hidden, and they can consume gigabytes of disk space. You can manually clear leftover files, but it’s a lengthy process and not the best way to use your time. That is why we recommend removing apps from your Mac using dedicated uninstallers or app cleaners.
If you delete apps from your Mac now and then, App Cleaner & Uninstaller is a must-have. It’s the stand-alone version of the uninstallation tool embedded in MacCleaner Pro 2.
App Cleaner and Uninstaller scanned our test MacBook in under 10 seconds and presented a summarized status of applications, extensions, installation files, and leftover files consuming storage space. You can also view and modify your Mac’s startup programs directly within the app.
In the “Remaining Files” section, App Cleaner & Uninstaller indexes all files leftover by apps deleted from your Mac. That’s what the app does best: cleaning files and folders associated with an app during uninstallation. It doesn’t scan for duplicate or large files, but it does an excellent job eliminating leftover files in macOS.
We should mention that App Cleaner & Uninstaller is also a paid app ($19.90). But, you can use the app for free for two days without making a payment.
This software bundles several tools that’ll help boost your Mac’s performance. With MacKeeper, you get security-focused utilities (an antivirus and adware cleaner), disk cleaning features (junk cleaner, duplicate finder), and other performance optimization tools.
The one-click smart scan feature will scan your Mac’s system drive for security vulnerabilities, clean out unwanted files, diagnose and performance issues.
MacKeeper is a paid app that operates on a subscription model (price starts from $5.95/month). However, the free trial version gives you access to malware scans, real-time antivirus protection, and other disk cleaning features for a month.
Launch MacBooster, and you’ll find a collection of nine tools designed to optimize your Mac. The System Junk remover scans for app cache files, broken login items, leftover files, system log files, iTunes cache files, etc. The app uninstaller also does a thorough job. It swiftly scanned apps installed on our Mac and presented all preference files and supporting files associated with an app.
If your Mac takes several minutes to boot, use MacBooster’s Startup Optimization tool to increase boot speed by removing unneeded startup or login items. Fun fact: MacBooster detected more startup items on our test MacBook than other cleaner software in this list.
Although MacBooster is a subscription-based app (starting at $2.49/month), we could access all features in the trial/free version. We couldn’t find any information on the developer’s website. However, we expect the free trial privilege to end after some days.
This is another reputable cleaning software with disk cleaning tools, speed optimization options, malware remover, storage management features. CleanMyMac is an all-around tool with all the features a cleaning software should have. It’s a paid app ($39.95/year), but you can sign up for a free trial to test its features.
Read our CleanMyMac X review to learn more about the app, its features, shortcomings, and how it compares to other macOS cleaning tools.
To a Safer and Faster Mac
While these cleaning apps can help prevent attacks and free up your device’s storage, they can pave the way for hackers and other malware. So, ensure you install only reputable apps, preferably from the App Store. Likewise, read recent reviews of the software before downloading or installing. You may discover new attacks or vulnerabilities the software poses to your Mac—if any.
