Hopefully you guys have some answers as I'm not sure what to do.

1- I keep getting error 8003 and can't empty my trash of certain items no matter what I do and I restarted my Macbook. I also haven't used Time Machine if that matters.

2- Nothing shows up in the 'Today' or 'Yesterday' section of my finder when it used to.

3- Not really a problem but I'd say a day or two ago it started asking for my password at start up and I never changed any settings to make it do that.
