Safe Boot?... What the..

[Sdahe]

Yesterday my MBP took almost 1 minute to shut down and today when I turned it on it took like 2 minutes and the login window had this thing in red - Safe Boot.

What could this be?... I reboot and everything came back to normal.

The only thing I did yesterday was some updates from Apple and one of my friends that used my computer for a while in the Internet. I hope he didn't mess up my computer!

I have backup in time machine so maybe I can restore the computer back to where it was.

Thanks for the help

Here it is according to Apple Support:

I've only used it one time...

Mac OS X 10.5.6 or later: A Safe Boot deletes the dynamic loader shared cache at (/var/db/dyld/). Restarting recreates this cache. A cache with issues may cause a blue screen on startup, particularly after a Software Update.

So this happened because the update I did... I though that my friend did something wrong in the computer.. jajajaja!!!

You can boot into safe boot by holding the shift key just after the startup chime. Is there a chance you hit the shift key?

I don't think so but maybe I hit it by mistake...
