Mac OS X Tiger seems to be the most stable and dependable Mac OS to date.

So why are there so many Mac maintenence utilities? Check the price tag. The Top 7 Utilities are free.

Does that mean your Mac running on OS X Tiger doesn’t need maintenance?

The truth is that Mac OS X is highly sophisticated, very complex, and needs a little tuning here and there.

There are caches to be dumped, hidden features to be opened, logs to be deleted, and much more.

Should your Mac begin acting a little wonky, start looking for reasons and start with a few of these free utilities.

#7 – MacJanitor

Not all Mac maintenance utilities are created equal. Enter MacJanitor.

Dig intro cron and other goodies with a set of utility scripts for Panther and Tiger. There’s no Intel version yet and MacJanitor was last updated over a year ago.

#6 – Maintenance

Titanium Software has two of the top free maintenance utilities for Mac OS X.

Maintenance sports the standard fare of repair permissions, run scripts, reset Spotlight and more.

Cleaner

# 5 – Cocktail

This superb little utility has been around awhile so expect to devote time to reading the reviews on Cocktail at MacUpdate.

As with most Mac OS X maintenance utilities, Cocktail is general purpose in the Swiss Army Knife mode.

The lack of brushed aluminum makes it a favorite almost as much as the lengthy list of tools and tweaks.

#4 – ultimateTask

The geekier among us may love the elegance and depth of ultimateTask and a companion product, rootMachine.

Anything that helps me get rid of Dashboard is fine with me.

#3 – MainMenu

High on anyone’s shopping list from Santa is Santa’s MainMenu.

As you might expect, this suite of maintenance utilities sits in OS X’s menu bar.

That means getting a cleaner, healthier, shinier Mac is just a click or two away.

#2 – Onyx

Doing a little more for less (or, the same price, since everything’s free) is Onyx.

No brushed aluminum left over from Panther days, Onyx opens up hidden features, deletes caches and hidden files, and lets you look at logs.

#1 – AppleJack

Frankly, any of the Top 3 could be #1, but AppleJack has a few extras.

Can’t even get Mac OS X to show up on the screen? AppleJack to the rescue in single user mode.

There’s the standard fare of repairing permissions, validating files, and killing corrupt caches.

The Top 5 are ready for Intel Macs, but all seven maintenance utilities are essential tools to keep your Mac running clean, lean, and mean.

Can you pay money and get the same thing? Yes. Among those maintenance utilities with a price tag, I prefer Xupport and Macaroni.

The latter costs less but comes with more stars. The former costs more and does more but has less stars. Your mileage may vary.

What’s your favorite Mac maintenance utilility? Did I miss one that should be on the list? Are these utilities even worth using on your Mac?

Update – I’ve used Cocktail for so long that I mistakenly placed it in my Free List. A license is $15. I plead insanity, which, of course, comes from my child.

Allow me to remove Cocktail from the Top 7 Free Utilities (since it’s not really free, Alexis—duh), and replace it with the capable Mac HelpMate.

Though relatively new, Mac HelpMate is popular and straightforward with many diagnostic tools, and a unique screen sharing and remote access feature. Highly recommended.
