Hello, I have some questions that I'm hoping to find help with. I'm getting a 2009 White MacBook off of eBay for a pretty good price. But it only has 2GB of RAM, and a 5400 RPM HDD. I'd like to upgrade the RAM to 4 GB, which is pretty simple. However, my problem is with the HDD. I'd like to upgrade to a Samsung 850 evo SSD, but I don't know how to go about it. I've seen installation videos, but I don't know how it works. Being that it's a new-to-me computer that I don't have a backup of, when I put the new SSD in, how do I get Mac OS X onto it? It's currently running Snow Leopard. I'm not worried about losing data, because nothing on it is mine anyways. Do I have to make a backup first before changing over to an SSD to be able to boot into Mac OS X once the SSD is installed? Thanks for any advice, I am completely new to stuff like this.
