Fast Cleanup - Free

1. Clean up the user cache and log files.

***User Cache Files***

Your Mac's cache is where applications store pieces of data it needs to reference often. In most cases, your Mac's cache—both the system cache and application cache—makes your Mac run faster! But sometimes files in the cache grow too large or get corrupted , which can cause errors and application crashes.

If an application is crashing or showing errors, clearing its cache may help. Applications on your Mac create temporary files they can use to speed up performance. If the cache gets too large or contains a corrupt file, clearing out that app's cache folder can free up disk space and may improve application issues.

***User Log Files***

What Are Log Files?

Many different applications and operations on your Mac generate log files as diagnostic aids; they help you when something goes wrong.

You can often use Notepad to open and read them. In some applications, you can understand what the log says, but for the most part, the content is pretty meaningless to most, and is really intended for support or technical folks.

Is It Safe to Delete Log Files?

If you're running out of space, you might want to clear out older logs to free up space. It's completely safe to remove application and system logs on a Mac, so you won't be causing any damage by doing so. Your Mac will automatically recreate any log files you remove, so there's no harm in removing them.

If the log file is deleted, In the case of an application needing to write a new entry and the file not being found, it will be re-created automatically. Some old log files, if not cleared, will take up a lot of disk space, they are basically useless.

2. Empty the trash bins

3. Clean up the uninstalled applications leftovers.
