When using a Mac for a while, you will see that the available storage space is getting less and less without knowing why. According to I’s experience using Mac, the main reasons come from installed applications, forgotten large files, and an increasingly bloated cache. I have used CleanMyMac to clean up my Mac, and I found it effective for the above reasons. In this article, I will guide you to download CleanMyMac for free for Mac and use it.
Download CleanMyMac for free
Because CleanMyMac is a lightweight application, according to me, downloading and installing CleanMyMac is quite simple. Follow these steps:
Step 1: Download the installation file and open the DMG file.
Step 2: Drag and drop CleanMyMac into the Applications folder.

Step 3: Use Terminal to allow CleanMyMac to open. Use Terminal to allow CleanMyMac to open. When you first open the app, you will see a notification to open the app. Click the Open button if it is available. But if you still can’t open CleanMyMac, you can bypass this error with a simple command in Terminal.

xattr -cr /Applications/CleanMyMac*.app
Using CleanMyMac
I have been using CleanMyMac for more than 3 years, and during that time, I have only used the cleaning-related functions because those are the core functions that users need. As for the Protection and Speed-up functions, I do not appreciate them for an application specializing in cleaning.
Uninstall multiple apps
CleanMyMac’s Uninstaller feature is very convenient when we need to uninstall multiple applications simultaneously, saving a significant amount of time compared to manually searching and uninstalling applications on a Mac.
Steps: Go to Applications, click Scan, click Manage My Applications, select Uninstaller, select the applications you want to remove, and click Uninstall.

Find forgotten large files
Large forgotten files are one of the leading causes of full storage. You have downloaded huge files and saved them somewhere in Downloads or Documents, and then months – years pass, you do not use them anymore, but also forget about their existence.
Steps: Go to My Clutter, click Scan, click Review All Files, select Large & Old Files, select the files you want to delete, and click Remove.

Right-click on a file name and select Reveal in Finder if you want to see where a file is located. This is useful if you want to move files to another location, like the cloud, instead of deleting them immediately.
Compare the size of folders
CleanMyMac’s Space Lens feature helps you track down the folders and files that take up a lot of storage space on your Mac. By listing the size of folders from heavy to light, you can drill down to see the subfolders and files inside. Based on my experience, I find Space Lens very effective in discovering the cause of running out of storage space.
Steps: Go to Space Lens, click Scan, go deep into the heavy folders to find unnecessary files and subfolders, and click Remove. Be careful with system files.

The Space Lens feature is temporarily missing from CleanMyMac 5. The developer commented on Reddit that they are redesigning the feature and will bring it back in the future. For now, to use Space Lens, download the latest version of CleanMyMac X.
Clear system junk
System Junk is files that are automatically generated during computer usage, such as cache, logs, and application updates. I clean the cache about 1 – 2 times a month, and according to Tachus, this is also the recommended frequency to keep the browser running smoothly and limit errors caused by old data.
Steps: Go to Cleanup, click Scan, click Review All Junk, select System Junk, choose the files you want to delete, and click Cleanup.
