So I've decided to purchase a 250 gig Samsung 840 EVO (you can see my earlier post in my history on how/why I decided on the EVO) to replace the current HDD in my early 2011 Macbook Pro. I'd like to do a clean install considering I already have the files I need/want backed up onto a USB drive. Additionally, I already have a bootable USB drive I will use to install Mavericks onto the SSD. All tutorials I've read online/watched on youtube just do a physical install of the SSD and a clean install of the OS without getting into the technical stuff. I just have a few of questions before I get started: 1. I know I will need a #00 phillips and a torx T6 screwdriver, but what exactly do I need to do besides physically install the SSD and install Mavericks off of the USB and onto the SSD? 2. Is there a certain partition/reformat method I have to do before installing Mavericks onto the SSD? 3. Are there any firmware updates I need to be concerned with? If so, when/how do I go about doing that? 4. Do I need to enable TRIM? 5. Am I missing anything? Thanks for your time. I'm obviously not the most tech savvy person and I apologize if this info is somewhere in the forums.
