after onyX cleaning, i recovered 6GB space, this s surprising, I don't know OS X took so much space for log/obsolete files and others.
The only places i can think of that might cause this un-necessary space hogging are:
1, Temporary and obsolete Files
2, Trash can
otherwise, i can't match the released space size.
