Take the 2-minute tour ×  There are a lot of applications that I
have no use for that take up space on my Mac that I want to
delete. When ever I try to delete them it says that it is an
essential part of the OS, which is bollocks because since when
is Chess an essential application?  share|improve this question
Is your question why Apple thinks Chess is an essential part of
the OS or how to delete programs that Apple considers essential?

application you would like to remove and Get Info on it, either
Command + i or from the Menu File>Get Info.  At the bottom of
the resulting window, in the Sharing & Permissions section,
change the "everyone" setting to "Read & Write". You will
probably have to click the lock in the lower right corner first
and authenticate as an administrator.  Once the setting is
change, close the Get Info window. You should be able to move
the application to the Trash without any trouble.  share|improve
