Some of the other things these utilities do: Read up before you try to optimize a drive: A journaled drive can get muddled if you optimize it.

If you receive an ad, pop-up, e-mail or phone call advising your computer has been compromised, this is a SCAM only intended to take your money.

How are you cleaning up memory Did it get dirty First assess what it is that you think you are fixing.

Did you get Cleaner with bundled software (Thats the most usual sourceat least you didnt pay full price).

You can selectively throw away cache files with Washer CleanMyMac, etc.

They all tell you that they have saved you Gigs of space, but how that was accomplished is often dicey.

Similar to deletions of shared software components on the Windows side registry: it might take out something that was not needed for an app you dont use decide to chuck, because it may turn out that component was shared with another application, so you wind up screwing up that other keeper application.

The fact is - many of these utilities have pretty interfaces, but give you almost no clue what they actually did.

Some give you a graphic wrapper over Unix command line functions, or access hidden functions the OS is capable of, like adding double arrows to your scroll bars.

Some of those features may be differently supported in the next OS update, or are largely useless in your work flow.

Like late-night infommercials that offer to solve problems you never knew you had: Know what you think you are fixing before trying to fix it.

The same goes for any other application claiming it will clean up your Mac or improve performance.

They are all crap.

There are a very few exceptions, however, those need to be used with great care and are really nothing more than a GUI front end to standard UNIX utilities that are already built into OS X.
