I notice the least slowdown when using Applejack. It fixed the small amount of damage OnyX did.

After using OnyX, I had an immediate speedup, followed by a steady decline in system performance.

In contrast, after using Applejack, my system slowed for a short amount of time, but stayed snappy longer.

I recommend Applejack over this app.


kinda slow but does what it's supposed to

Fantastic multi utility that combines things like macjanitor and tinkertool and does a whole lot more :)

Most recent version - for Tiger at least - is 1.7.4

tried to schedule the maint scripts. kept crashing every time i changed the hour, gave up and uninstalled it

This is a very handy maintenance utility. And it's free.

There is a more recent version available for Tiger: 1.7.1

one of the best pieces of freeware ever.
