Hello, Machine: 2011 MBP unibody with 2.4Ghz Intel Core 2 Duo. OS: Version 10.6.8 i am trying to replace the hdd from 240gb to 1tb sata, and i have some questions. i read many reviews/guide, but all requires using an enclosure or time machine or backing up existing first, but i think i want to do it differently, but unable to find guides to achieve what i want. my mbp does not come with recovery disk, and from what i read, the existing hdd has a seperation partition for fresh reinstall. I do not have a 2.5 USB Enclosure which makes it impossible for me to first install the new hdd before doing a physical swap. I want to get a fresh install without any software becuase over last few years, i installed a bunch of junk software which i do not want to carry on... and i think i have some spyware going on, so i just want to do backup manually (Files, pictures, documents), and i can reinstall software one by one myself. I have a seperate portable 750gb hdd, which i can use to backup my files to. But i do not know how to get a fresh mac os reinstall after I do a physical swap. I also want to upgrade to the latest MAC OS which is free, but i ahve been hesitant to do this with my existing HDD since its a waste effort. Can you suggest me what is the best way to achieve this? Thanks.
