My computer has been acting stranger and stranger lately, and I am certain that all of this Texas sun has fried the internals on my old MBP. Last night I started up my MBP w El Capitan, and after logging in, I got a grey screen with a large apple on it and that is it. My MBP wouldn't finish booting up. After 5 minutes, I did a hard shut down and tried logging in to my admin account - thinking I needed to rebuild permissions. Same issue. Fortunately I have a clone from a month and a half ago that I am using to type this plea for help. Unfortunately, I have been waiting on a new HDD to come in the mail, and it took me all week to burn the new one in, and I was going to do a clone of my MBP today, until it died last night. My #1 priority it to get all of my data backed up from my internal HDD, but I don't know how to do that since I am running on an external HDD now. Why does this sh*t always happen right before you do a backup?! Oh, one more thing... For now, I can see all of my data on my internal HDD, which is good. I am thinking that El Capitan - maybe due to failing hardware - died on me last night - but at least for now my data is still there. Please help!!!
