The Leopard 10.5.7 update, the keychain and the clock.
I installed the 10.5.7 update for Mac OS X Leopard and after logging in i got a prompt that the system date was reset (to 1990-something). I am using the automatic date setting which gets the current date and time from apple.com so I figured that it was no biggie. But after a short while I noticed that I have no wireless network connection and that the password for the network was blank, which is odd, since I am supposed to have this password saved in the keychain.
I opened up the keychain access and checked the "show password" on the wireless network in my office (I don't remember it, ofc ) and i got a message that "Access to this item is restricted.".
After a lot of digging around (on another laptop) I found out that if the current system date is earlier than the creation date of your keychain file (~/Library/Keychain/login.keychain) you cannot view the items in it. So here's a loophole: No internet - can't set correct system date - no correct system date - no internet ....
Luckily for me, I devised an extremely clever plan - I manually set the date to today, got the keychain working, and then switched back to auto-date. Ha-ha.
