Im' replacing my HD with an SSD. I figured I could just download a copy of yosemite onto a USB thumb drive from my macbook pro. Then plug in the thumb drive into the mini. I don't want to have to transfer anything over from the old drive. I just want to install the new one and go from there. So some questions: After booting up the mini with the new SSD, can I just boot up in disk utility and install Yosemite from USB? If I download yosemite from my macbook pro, is it a different copy than what needs to be used for the mini? I could just do it from the mini then. Thanks.
