As most of you, I am very pleased with this product and its price. Although the "Automation" feature seems a bit slow in running on a 1.8 Gig iMac G5 with 1.5 Gigs of RAM--and has unnerving and unexplained pauses while running--everything seems to work as advertised. It is very convenient for discovering versions installed on your computer. They might add a feature to disclose the firmware version and perhaps the versions of printer and scanner drivers, but that may be going far afield. I don't know any application that can determine the S.M.A.R.T. status of a "foreign" disk, but if any of you know of one I would certainly be interested to hear of it. This application does more for free than almost any application I know. I keep it in my "Unused Applications" folder of my Applications Folder only because it isn't something anyone needs to run every day. But every once in a while . . . .

If there could be popup explanations for each selection choice, I think it would help a lot of people to make wiser decisions about how to use Onyx. There are a few warnings scattered through the panels, but whenever one is for example cleaning or deleting--especially with a new broom--every bit of information helps. Going to the "Help" menu each time is a rather tedious process with so many little items to choose among. I haven't tried optimization with Onyx, as Apple seems to optimize everything when new updates are downloaded. I have had BAD LUCK with some other optimizers in the past; but as I say, I have never used Onyx for optimization.
