I have a 2009 macbook running sierra. I want to upgrade to something bit newer and faster. I'm on a low income so buying a new mac is out the question. So I have been looking at refurbished macs. Found a refurb A1278 i5, 4GB, 500GB at a supplier. They can help me out with finance. Now here is the thing. My macbook works all well and good but can lag at times at work. But the finance deal is £744 (£31p/m over 24 months) I could afford this but.... Buy time I paid it off it more than an ebay item (which I cannot afford outright) and a step up on my 2009 model is it still going to be supported as it a 2012 model. It has usb 3.0 so be good for my usb sticks and HDDs as they usb 3.0 plus the sd slot means can download my dashcam vids with a card reader. Am I just being silly and should I save for few years and buy a new macbook. How many here have been in similar situation? what did you do?
