Hi, I have been using Macs since buying a PowerBook back in the early Panther days. I know it's ridiculous, but I've got into an obsessive routine when I start up my computer... I power up and wait for OS X to load (Snow Leopard, at the moment), initiate and dismiss Dashboard to get it responsive, then open Disk Utility and repair Disk Permissions. I do this every time I start up my computer. I don't have any applications set to open automatically at startup but I then manually open iTunes, Twitter, Mail, Reeder, Safari, iCal and Things before I get to work... Now, when I upgrade to Lion I quite fancy having all these items open automatically, some of them (iTunes and iCal) in full screen mode... My question: is there any disadvantage to abandoning my long-held permissions repair routine? Or was it pointless all along? It was from forums like these, and scare stories, that I got into the habit in the first place, by the way. I also used to use the Terminal to run the cron scripts, but somehow managed to break the habit... Steve.
