Your 2 cents, do I need to defragmentate my MAC HD?

    This is my 1st mac and since growing up with windows I was/am still very used to the fact that I would defrag my windows pc around New Year.
    Do I need to do this with a Mac too? It has not been running slow or anything, but I like to keep things working optimal.

    Thanks in advance for your replies.

    Sure don't! The whole point of a journaled filesystem. Enjoy it!

    Behind you
    still hits performance like a truck after a while.

    My two cents, and it goes against the grain.

    Yes, you SHOULD consider defragmenting your internal drive, particularly if your drive is getting filled up and/or you're experiencing "sluggishness".

    I recommend "iDefrag" -- excellent product very reasonably priced.

    "Between the Hedges"
    Under normal conditions, I would say "no"
    It would be very rare to recommend defragmenting

    But I would not do anything without a current backup

    And I would probably be more inclined to do a fresh install or a clone and restore before I would consider defragging

    Not except in specific circumstances, and even in those cases I wouldn't say it hits performance 'like a truck'. And the technical details have already been shared in articles. The only reason I've ever had to mess with defragmentation was a case when Bootcamp couldn't manage to create its partition on a hard drive which had been used for years.

    That entirely depends on what you have installed and running and how you use your system. I've been running for almost 3 years on my current MBP and I've never defragged, never repaired permissions, never had any problems with constant beachballing, never had a kernel panic, never had to reinstall an app, and my system runs just as fast and problem-free as when I took it out of the box. I use Safari and frequently have 20+ tabs open simultaneously, in addition to Mail, iCal, Address Book, iTunes, TeamViewer, Skype, Preview, TextEdit, MS Excel and several other apps and widgets open simultaneously. In other words, I use my system a lot, typically 14-18 hours a day.

    So when is this "performance like a truck" supposed to kick in? :rolleyes:

    I'd call it a placebo, except that placebos work.
