Top 5 Most Popular Cleaners

Macs are loved for their reliability and polish. But, like all computers, even Macs tend to slow down with age. When that happens, many people choose the nuclear option: a complete system reinstall. There are cases when a full reinstall is really the best course of action, but using the best Mac cleaner apps is much faster and often just as effective.

Testing most Mac OS X cleaners available, we’ve selected our top 5 favorite free and paid cleaners for your Mac.

Top 5 Best Mac Cleaner Apps in 2021

A great Mac cleaner must support the latest version of Mac OS X, it must be easy to use, and it must deliver on its promises. As much as we like free Mac cleaner apps, we’re not excluding paid cleaners from this list. Often, paid cleaners come with the best features and the most reliable support. Paying a relatively small amount of money for a Mac cleaner makes a lot of sense if it can extend the life of your Mac computer for another year or two.

What Is Mac Cleaner and How It Works

Mac Cleaner
A Mac cleaner is an app designed to speed up your Mac computer, making it as fast as brand new. To understand how Mac cleaners work, you need to understand why Macs become slower with age:

☁️ Lack of Free Storage Space

Perhaps the most common cause of Mac slowdowns is the lack of free storage space. It’s, unfortunately, no secret that Apple charges a premium for large storage devices. Base models are usually offered with much less storage space than comparable Windows or Android devices. The Mac OS X operating system alone takes around 10 GB of space, and large apps and games such as Microsoft Office, Adobe Photoshop, World of Warships, or War Thunder make the number skyrocket.

Without any free storage space, Macs have nowhere to store temporary files, which can cause the entire operating system as well as all apps to come to a crawl.

Mac cleaners address this problem by deleting the leftover system and app files. They also help users identify large files and folders and either delete them or move them elsewhere.

📁 Stale Caches and Temporary Files

The Mac OS X operating system stores a lot of information locally to improve loading times and make websites and apps more responsive. Sometimes, the locally stored data become outdated, potentially causing all sorts of issues. This most commonly happens when browsing the Web.

Most Mac cleaners allow you to quickly and easily empty stale caches and delete old temporary files, which causes websites and apps to send you the latest copies of data. You could, for the most part, achieve the same results even without a Mac cleaner, but it would take you a long time to accomplish what Mac cleaners do with a press of a button.

🔀 Startup Background Processes

Every time you boot up your Mac computer, multiple critical, as well as non-essential system processes, load in the background. The problem is that some apps are designed to behave in the same way — even if there’s no good reason for them to start automatically in the background! What’s more, these apps continue to run in the background until you manually close them, eating up your precious hardware resources.

If you want a clean Mac, make sure to identify all processes that automatically start in the background and only keep those you really need. A good Mac cleaner can identify startup processes with a significant negative impact on the boot time and disable them.

How do you clean out your Mac to make it run faster?

A Mac cleaner is a software solution that scans your computer’s disk storage to identify the items that are taking up space. The objective of a Mac or MacBook cleaner is to find unnecessary files that are no longer needed to run your applications so they can be deleted to free up disk storage.

Let’s look at how Mac cleaning software works. We will demonstrate the steps required to run a Mac disk cleaner using Disk Drill, one of the best free Mac cleaners available.

  1. Download and install Disk Drill on your Mac. The free trial version of the software is all you need to run the cleaner app.install disk drill clean up software

  6. Open folders and subfolders to identify specific files. Check the box to the left of the files and folders you want to delete from your Mac.
  7. When you are finished making your selections, click the Remove button in the lower-right corner of the app’s window.select files and remove them
  8. Click OK on the confirmation prompt to perform the deletion or cancel if you want to rethink your selections.confirm procedure
