Before the Software Update:

If you decide to install macOS Catalina on your computer, we advise using these five helpful tips:

Preparing your Mac for a new update is a convenient time to clean up your computer from unneeded equal files. Just download the free Duplicate File Finder app from the App Store to easily and quickly remove duplicates.

Clear cache and other unneeded files. You can delete temporary files, like caches, logs, and downloads from your disk. To remove these junk files, you can use the ClearDisk application for Mac.

Delete media files. It’s likely that you have lots of old and large files stored on your Mac. Generally, the largest portion of them is media files.
