    It's been weeks now. My mac has forgotten everything. Some stuff just pop ups, and then I have to approve it or not. Stuff like if I give some program permission to do something. And then it always forget the password to wi-fi. Everytime I restart it or it goes on sleep mode, it asks for the password. And today I can't even get on the net because it has forgotten the ip-address.

    It all began after I restarted my mac normally, as usual.

    Someone who know what is wrong, and tell me what to do?

    Sounds like you need a new PRAM battery.

    Just pick up a new CR2032 Lithium battery from your neighborhood drug store and replace the one in the machine.

    Thought, I guess you could try reseting the PRAM first and that's holding [Command + Option + P + R] on the keyboard before the gray screen pops up.

    I don't think it's the PRAM battery as the type of configurations he mentions usually are stored on their own plist file. Try repairing permissions.
