Firstly, if I were to make a list of top most useful, critical and generally indispensable utilities for the Mac...ever...AppleJack would top the entire list. It has for years now. It is, hands-down, the most useful utility I've ever employed and I have been using it through all its updates from Tiger on.

I give the developer so much credit for keeping this indispensable little utility free for the masses of Mac users out there while a bunch of others like MainMenu have sold out to folks who now want to charge money.

The AppleJack developer has provided something that by its very nature of being free and more useful than all the other ''wanna-be'' system maintenance-optimizers out there, and for nothing but the thanks of a hard-core, fiercely loyal group of followers, something very special.

You have my whole-hearted thanks and hopefully others of us out there will add to this and let you know we appreciate your continued hard work. You are one of the ''good guys'' of the Mac world.

Knowing in advance that it was incompatible with Snow Leopard 10.6, I used it ''one last time'' in 10.5.8 just prior to my move to Snow Leopard, I then sadly uninstalled it and then installed the Snow Leopard update. I miss AppleJack and look forward to ''reuniting with a long-time friend soon.''

Until then I have had to settle for the demo version of Snow Leopard Cache Cleaner. It works okay but to borrow a quote from the Hertz car commercial, ''there's AppleJack and not exactly.''
