Hello guys i decided to switch from gaming to creating websites, developing apps, and programming software. I am 15 years old and money is a big thing. I currently have a computer which is worth about $1,000 but I do not know whether or not I should sell it. What in your guys opinion is a good MacBook for under $900 that will be good for my needs and will last me a good time. I am ok with buying used items if that isnt a problem. Thanks.
