thanks sig for your reply understood..
and thanks linc for the advise: P.S...
First, its a discussion room and i didn't expect anyone to speak for apple, if needed i would contact them directly, it was just a question. jeez thanks for making my first "post on this really pleasant, for future ref, if you really want to help great! just dont come off as such a douche ( and i mean that in the nicest way seriously)
Second if Apple did not recommend any third party software, their app department would be pretty scarce as most of these are 3rd party apps,
However i really appreciate the time you took to reply, i'll take your word for it and not bother with mackeeper.
