20 CleanMyMac X Hidden Features You Probably Don’t Know

CleanMyMac X, IMO, is one of the essential Mac apps you should install if you care about your Mac’s performance.

This junk-cleaning app, along with other similar apps like OnyX, DaisyDisk, MacFly Pro, MacClean, BuhoCleaner, AppCleaner, etc., does similar things. They scan your Mac looking for (and delete) junk files in ways impossible to be done manually.

However, in this post, I’m not going to talk about cleaning up junk with CleanMyMac X. Instead, I’m going to shed light on other (great, if you will) hidden features of CleanMyMac X you probably don’t know.

1. Repairs broken file and folder permissions

Maintenance > Repair Disk Permissions

Since macOS is a UNIX compliance operating system, all files and folders are attached with permissions, as all UNIX systems do. If you encounter any problems with permissions for files and folders (i.e., unable to move or delete files, not owner of a file or folder, etc.), this can be easily fixed using CleanMyMac.

2. Reindex Spotlight

Maintenance > Reindex Spotlight

Mac’s Spotlight is a great tool for searching for apps, files, or just about anything on your Mac. If you noticed the following symptoms when using Spotlight, that probably means you should re-index it again for better performance.

  • Searching is slow.
  • Existing apps or files do not show up in search results.
  • Spotlight is stuck, and it does not search.

3. Erase private files

Shredder > Select File > Shred

Sometimes deleting files to trash won’t give you peace of mind, especially regarding highly sensitive files (or folders). CleanMyMac lets you delete them securely without leaving a trace and ensure they are unrecoverable.

4. Clear all browsers’ histories and other data

Privacy

Cleaning a browser’s history, cookies, and browsing history doesn’t seem like a tedious task, but if you constantly use a lot of different browsers (Firefox, Chrome, Safari, Brave, etc.), then wiping all these data off can take some time.

CleanMyMac’s Privacy feature allows you to check all the browsers you want data wiped off and remove them with just one click.

5. Delete all previously connected Wi-Fi Networks

Privacy > Wi-Fi Networks

Your Mac keeps a record of all Wi-Fi connections you’ve previously connected to. You can find the list under:

CleanMyMac shows you all the Wi-Fi networks and allows you to delete all of them (or a selected few) in one simple interface.

6. Discover which apps have access to your Mac

Privacy > Application Permissions

Do you know what app has access to your Desktop Folder? Or, do you know what app can access your Camera?

Head over to Privacy in CleanMyMac, click Scan and look under Applications Permissions to find out all the apps that have access to various parts of your Mac’s functionally, devices, or system features.

7. Bulk update outdated apps

Updater

If you install any Mac apps manually via the .dmg file, you will have to manually update them if they have gone outdated. To find out – manually – which apps need to be updated can be a tedious job.

Updater in CleanMyMac gives you a list of outdated apps; it also allows you to bulk-update all outdated apps.

10. Find out space-hogging files

Large & Old Files

Ever wonder what takes up most of the space on your Harddisk drive? Are the photos, movie files, documents, or applications installed? There are a few ways to find out and delete them to save space.

You can either use the Storage Management app on your Mac or you can use CleanMyMac’s Large & Old Files feature. IMO, the latter gives a clear picture of things.

11. Backup files instead of deleting them

Large & Old Files > Select File > Move to Folder

Now, after discovering what’s hogging your hard disk space, you can either delete them and never have access to them again, or you can keep a backup instead.

CleanMyMac allows you to select all your large and old files, and instead of deleting them, move them to any folder (on the current system or connected NAS) you prefer.
