How to update Macbook Pro mid 2010 to the latest version?
So my main computer that I use recently broke so I'm using a old Macbook Pro from mid 2010. It's currently on OS X 10.9.5 and I was wondering how to update it to the latest version. Every time i try to update it it says I need version 10.10 but I can find it anywhere.
