So I have a Macbook Pro mid 2009 13 in. I installed yesterday a 8gb RAM upgrade, and my computer is bootcamped to run windows 7 as well. Now when I start up the Mac side, a gray loading bar appears below the apple logo, and booting now takes 10 minutes. I thought I'd check online to see what it is, go figure I can't get online, though it says I'm connected, tried Firefox and Safari. Switched to Windows and found that the internet works fine on that side, firefox. So back to mac, I tried to look in activity monitor for something that stands out. Guess what, Actvity Monitor is completely empty, and shows no sign of anything or movement. What is suddenly happening to my Macbook Pro? This started around last night, should I perform some step after instaling the 8gb RAM upgrade? Seemed to start after I did that. Thanks for the help guys.
