the Mac does not have a registry.
However, there are apps like Cocktail that will do a little housekeeping for you.
Alternatively, you could leave you iMac on 24/7 and the built in CRON jobs will do housekeeping for you in the wee hours of the morning
i saw an ad on yahoo home page for a product (software) called SAMMSOFT.
this product is supposed to search out and delete registry problems than can slow down a computer.
sounds interesting, however i am sure it doesn't work on macs. is there a product that will do the same for my imac?
imac, 10.5.8, intel core 2 duo, 2ghz, 1 gb
