Can anyone recommend me a best mac cleaner software?

There are tips you can use to free up more space without using Mac cleaning software. Manually cleaning large files and cache is a way to free up storage space by directly deleting files and temporary data that take up a lot of space.

Large files (e.g. videos, installers) and cache files (e.g. browser cache, app cache) usually take up a lot of space, but they are often easily overlooked. Manual cleaning can pinpoint and delete these files to free up space. And there is no need to use a Mac cleaning software within the trick.

Delete large files

1. Open Finder. 

2. In the menu bar, click ‘File’ > ‘New Smart Folder’. 

3. Click the ‘+’ button in the upper right corner to add filter conditions: Select ‘Type’ as ‘File’. 

5. Select ‘Size’ as ‘Larger than’ and enter a value (e.g. 100MB). 

macOS will display all large files that meet the criteria. Browse the list and delete the large files you no longer need (e.g. videos, installers, etc.).

Clear the app and system cache

1. Open the Finder. 

2. In the menu bar, click Go > Go to Folder. 

3. Enter the path ~/Library/Caches and press Enter. 

4. Once in the cache folder, you will see several subfolders, each corresponding to a different app's cache. 

5. Select the unwanted caches folder, right click on it and select ‘Move to Wastebasket’. 

Note: Do not delete the whole Caches folder, only the sub-folders.

Empty Trash

1. Right-click on the Wastebasket icon on your desktop. 

2. Select ‘Empty Wastebasket’. 

3. Confirm the operation and permanently delete the files in the wastepaper basket.
