How to Clear Temp Files & Clear Up Disk Space on Mac

The temporary files are created by a program on your Mac to keep the data temporarily. As the name suggests, these files are temporary and will be deleted automatically over time.

Following are the 4 types of temporary files on your Mac:

  1. Intermediate document versions
  2. Outdated system logs
  3. Browser cookies
  4. Application cache

Temporary files can be deleted by two methods.  The first is manual deletion which may be risky and the second is using tools that will save you time.
