[solved, scroll down to EDIT] Heya, first time here because i just got a HUGE ptoblem with Leopard. Installed and everything went fine, then tried to connect to the computer through my MacbookPro. Wow, i said, they improved the permission rules! But i want to access the entire disk, right? Then added it to the shared documents. But i do not want other to read my volumes, let's change those preferences. Here came the problem:i clicked the wrong line and then set "no access"....but to ALL ADMINS!!!! The disk's icon then cahnged into the one that ahve folders when they are not condivided and everything then freezed....Doing the startup again causes the blue screen to appear and stay...the computer is unusable and the disk cannot be seen through network. I am trying right now to install Leopard even on my second disk and i hope i will be able to reset the permissions. Anyway... WATCH OUT! And to Apple: it would be nice to add a damned WARN message to prevent dorks like me to commit such a suicide. [EDIT]: That fixed the problem. But what if i hadn't got another disk on the same machine?
