i'm looking to buy a used MAC to start my personal projects going on. I have some ideas of apps, they're very simple, couple of screens max and very basic functions. I have a very limited budget. I was searching for some used macs that supports El Capitan because of Xcode 8.2.1.
I have come cross 4 macs.
Mac Mini Early 2009 Core 2 Duo 2.0 4GB old owner added more RAM
MacBook Pro Late 2007 Core 2 Duo 2.2 2 GB
Macbook Air Late 2008 Core 2 Duo 1.6 2 GB
Macbook Late 2008 Aluminium Core 2 Duo 2.0 2GB
My question is, will i be fine if i used any of them for development? Which one is the best? If none of them are good enough, which one is the cheapest that i can get? Thanks!
