New Macbook Pro Retina Display keeps freezing.
I bought my Macbook Pro Retina Display (2015 edition) about a week ago and have so far been using it mostly for general online browsing (on Safari), and using apps like iTunes and Notes. In this one week however, there have been two instances when, while on Safari (both of these times I was googling the definition of certain terms), the computer completely froze; the cursor wouldn't move, and I couldn't 'click' on the trackpad either resulting in me having to force restart the laptop using the power key. The computer worked fine after both times I restarted it, but I still can't help but worry about why this might have happened in the first place. Does anyone have any suggestions as to how I can deal with this? Thanks a lot!
MacBook Pro with Retina display, OS X El Capitan (10.11.4)
