Hey guys, sorry if this has been talked about elsewhere, ive been looking but cant seem to find my exact situation. So my question is im upgrading my 2012 macbook pro today, with a 256 soldid state drive, 16gb ram, and regular hdd drive into the optical bay.. It came preinstalled with mountain lion, i want to create a thumb drive with a copy on it to do a fresh install of it on my ssd. How exactly do i go about doing that. Its not in my applications and i dont have it as a purchase in the app store. thanks again in advance.
