I have a 2012 MacBook Pro. A1278. It’s getting very very slow. Boot up is 5 mins. Random freezing. I thought it was just old. But I’ve done research and apparently it’s either the hard drive failing or hdd cable so I’m gonna replace both. SSD is gonna be faster anyways.
Question is: do I need to do anything to do a brand new install when ssd is in as I haven’t got a disc or usb install for OS X? I don’t want to clone or anything as all my important stuff is in cloud.
