So, everything was going fine for bit now. I also did a file vault on the laptop to secure it. not sure if it was the few updates to mavericks, i notice when i reboot the system and i get to login screen, i enter password and when i go in, the animation of the desktop coming up shows up laggy as if its struggling to come up. Then I try maps in google and street view seems laggy too. so not sure whats happening. i did disk repair etc. and permissions so wasn't sure.
