You won’t regret cleaning up pools of unwanted files from your macOS Catalina, as doing so optimizes your Mac performance instantly and lets you reclaim the storage drive space.

But you may find it difficult to distinguish between essential and unwanted files and accidentally remove crucial files in the clean-up process, resulting in data loss.

So, before you clean your macOS Catalina or an earlier version, click the Time Machine icon from the menu bar and select Back Up Now to back up your start-up disk. Then, wait till Time Machine performs incremental backup of your Mac hard drive or SSD. Next, go through the various methods below to achieve the Mac clean-up task.

1. Empty Your Mac Trash Folder

Warning: This may cause data loss; hence, backup your Mac before proceeding.

You can clean out Trash files without using the mouse by pressing the “Shift + Option + Command + Delete” keys. This quick cleaning is helpful when you’re sure that there are no vital files left in the Trash. If you’re not sure, manually browse your Trash folder to put back essential files to their original location, and then empty your Trash folder to regain used Mac drive space.

2. Remove Unwanted Files from Download Folder

You must have downloaded the best Mac apps or videos for your macOS or OS X. But did you remember to move all the used DMGs, zip archives, and unwanted large video files to Trash? 

Go to the Download folder and press-hold Command + I to get info about the Download folder. Don’t be surprised to see the enlarged size of the folder due to unwanted files. Remove all those unwanted files from the Download folder by sending them to the Trash immediately.

3. Clean Up Duplicate Files from iTunes

Music files can easily get duplicated in iTunes. But don’t worry, iTunes can help you find the duplicates for removal. To find duplicate files on iTunes in macOS Catalina or other Mac operating systems that support iTunes, launch iTunes, then go to View > Show Duplicate Items. The app lists all the duplicate music files by name, artist, or group items. To remove the identical files, uncheck the original files and leave the rest checked. Now, click on Edit from the iTunes menu bar and click Delete. This process cleans up your iTunes duplicate files.

4. Clean Up Caches from Your Mac

If your Mac SSD or the hard drive shows the error message, “Your start-up disk is almost full,” resulting in Mac freezing or other issues, then go ahead and clean up your Mac cache files. Make more space available on your start-up disk by deleting files. Removing large stockpiles of caches can help you reclaim your wasted drive space.

One shortcoming of cache deletion; some of the macOS or Mac OS X apps, such as browsers, may behave slower than before. But the creation of new caches will fix this problem later.

5. Uninstall Useless Applications from Mac

Mac storage drive cleaning process is incomplete without removing unwanted freeware, shareware, widgets, and plugins. First, get rid of all sorts of useless and unused applications from your MacBook (iMac) running or macOS Catalina, then empty the Trash to free up the occupied drive space. Uninstalling useless apps will also speed up and optimize macOS Catalina performance.

6. Back up Your Mac and Fresh Install macOS Catalina

There may be unknown causes of slow Mac; that’s why you should go for a fresh installation of macOS Catalina after taking the full backup with the Time Machine. Better upgrade your Mac to the latest macOS Big Sur 11 and see the change in your Mac performance. You can also clean an old copy of the sluggish and freezing macOS and replace it with a new one.
