I am looking to buy a MacBook for the sole purpose of installing and using AFNI (I will be attending the bootcamp in July). I don't want to spend an unnecessarily high priced model but also want to make sure I buy a machine that is up to the task (as a lifetime PC user, I do not speak Apple). In addition to ensuring that it has at least MAC OS X, what other specs should I be sure to look out for? I am assuming springing for the MacBook Pro with 16GB as opposed to 8GB is a must? Any advice would be greatly appreciated!
