So I just ordered 8GB of Corsair ram as well as a 250GB Samsung 840 Evo SSD for my macbook pro early-2011. I was wondering how I would go about doing everything when the things get here. I understand that I probably shouldnt change both at the same time, so I will add the memory first, test it, then add the ssd. I am not going to be adding the ssd as a secondary drive, I want to replace the hard drive that is currently in my MBP. I do not need to copy files over between drives because I can just mount the current harddrive to my desktop and recover files that I need. So the two questions I have are: Will the ssd fit perfectly into the slot that the harddrive is currently in, or I am going to need to do some interesting things to get everything to fit properly?, and can I literally just place the ssd into the computer as a blank ssd and boot it up, or do I need to preload macos on it or something? From my knowledge, I always thought that you could have the laptop automatically setup on a blank disk for you, but I wasn't entirely sure. Thanks Edit: Will I need any additional tools other than a screwdriver to open the macbook?
