Has anyone seen a version of CCleaner (Piriform Software) that will work with Mavericks yet?

CCLeaner for Mavericks now released...http://www.piriform.com/blog/2013/10/30/ccleaner-for-mac-update

As I said I was not thrilled. I stated it did allow me to block comm traffic by port, app, or other factors. THAT was interesting.

Regarding Nortan: As I said I was not thrilled, but it did allow one to block say, any In/Out comm by port, app, etc. I found that informative. The rest of its features (virus protection, etc), I'm not qualified to judge.

Very informative. I also have used CCLeaner and Onyx on my mac and was impressed. (sadly in this field thats not hard) I'm much more aware, or at least comfortable w/biological informatics. Said systems are robust, as in forgiving. Both CC&Onyx were straight forward and not "cryptically cute". Both products were very effective at saying: "If you don't know exactly what you're doing, don't"

Constructively humbling, and robust enough.

I have never used CCleaner, but I have used OnyX. OnyX has a robust set of tools, but as you point out, they are only needed if you have specific problems that a specific tool helps with. It would be nice if they had a list of symptoms that helped you determine which tool to use. I haven't needed it in a few years, so if they've implemented something like that, great.
