Your startup disk should have at least 15% of a free space to run properly. So if you have 500 Gb drive, the goal is to free 75 Gb for various system requirements. And it is easier to do than it may seem. System folder is a place where some of the hidden activities of your mac’s usage are stored. Sometimes we just forget to control them.

Cleanup System Folders

  • First of all, check you Trash

    We frequently delete files, but do we empty Trash? If you do not empty Trash at least once per week, one day it may contain up to several Gb.

  • Clear out Downloads

    How many times have you downloaded files from the web? All of them stay unorganized in this folder. Several Gigabytes of free space as well.

  • Renew Caches

    It is recommended to delete them once per month. Otherwise rather than speeding your Mac, they slow it down. Up to 2 Gb. Note: some apps even after removal leave cashe files.

  • Language Resources

    The most misjudged space eater. Language Resources is the data stored by apps for different language localizations. So do you need iTunes translations for Vietnamese? You may have up to Gb of completely wasted space.

  • Check Documents, video & images containing folders

    Even if you want to keep them as memory, there is no point to store them on your startup disk (that is performed by default).

  • Clear iTunes folders

    Especially be careful with folders having audio & video podcasts, mobile applications and music. Do you now that iTunes automatically downloads updates and new series? Imagine how much space it may take.
