Hi guys, I’ve been using a mid 2010 mac book pro running snow leopard. The hard drive recently died and disc utility was unable to repair it so I’ve had to do an erase and install. As I’m reinstalling snow leopard from fresh I was thinking about updating to Yosemite. My question is as I’m using a mid 2010 mac book pro, in regards general performance would I be wise to stay on snow leopard or update to Yosemite.(considering the machine is a little old) The machine isn’t used for any particularly power crunching tasks. Many thanks for any insight you can offer.
