Some log files and temporary files can be generated during system and application running. Take the Safari as an example, an internet browser you might use every day. The temporary files record the information about the web pages you visited. It would accelerate the same webpage load speed when you revisit it next time, but the acceleration only works for the same unchanged pages. The longer you use the computer, the more potentially unneeded files will be accumulated. Without cleaning these files timely, they will eventually consume your disk space dozens of Giga Bytes and harm the Mac performance. You can remove them and save the disk space for better use.
EaseUS CleanGenius can fast clean the potentially unneeded files and recover the disk space. Please refer to the following steps:
System Caches locates at /Library/Caches. The directory is used to save the temporary files created by the system apps.User Caches locates at ~/Library/Caches. It is used to save the temporary files created by the user apps.
System Logs locates at /Library/Logs. It includes redundant files which are used for recording the activity of apps and system services for debugging purposes.
User Downloads locates at ~/Downloads. The directory contains the download files. Please be sure there is no important data before you clean it.
