Please help. I have never owned an Apple product and am trying to navigate the world of refurbished Apple Macbooks to then put Logic on for my daughter's music course. I do not understand all the different operating systems and processors so PLEASE can someone tell me the most basic requirements I should be looking for. We do not expect all singing and dancing, just something for her to use as part of her course. Also, will I be able to put Logic onto an older Macbook straight from the Apple website? Thank you in advance, from one very confused mum!
