Thank you for reading this. I upgraded to Leopard a few nights ago. Leopard got confused with my one and only user account. I've spent 92 minutes on the phone with Apple support and roughly an hour with an in-store Genius. A lot of the problems have been fixed, but I am CONSTANTLY having to going into files/folder to change the "permissions" so that I - yes me, the one and only user of this computer - have "permission" to use various applications. Can I make a one time change to open up all permissions? I am not worried about other people using my computer or hacking my computer. I don't care if it is wide open for the world to see; I just can't spend more hours and days changing individual permissions. Thank you in advance for your advice.
