Hello,
My macbook black bought new 2 months ago crashed when I was working in gmail. I was loading several mp3's to send a friend, Fairly large file. Safari crashed in the middle of loading up the email. When I restarted safari, and went back to my gmail account it seemed to be working fine. I tried to open and compose a new email. It spent a very long time working on that and would not let me do anything else in that window, I could not stop it to try and click on another function within that window. It would also not let me do anything on the tool bar at the top.
Tried to force quit the programs several times and it seemed to go in a loop without closing the program. I left the computer for a few hours to see if it just needed some time and still working on opening the email. Meanwhile my wife's internet worked fine, so the problem was not the internet connection. Finally I just shut down the computer by using the power button. Since no further force quitting worked.
Turned power on and Mac office wanted to update. So I let it update. Opened Gmail again to work on the lost email. I could load gmail but safari crashed after signing out of gmail. Opened Safari again and then tried to open gmail and the screen came up your computer must quit. Please use the power button and turn off. I did that and when I tried to turn the computer on the computer just beeps and does not start.
Any Ideas? Thanks!
