I want to buy a new MacBook for uni but I already the 2015 retina version, it’s currently lasted me 5 years the only problem with it is that the charge doesn’t last as long as it used too, I think the setting is just that battery should be replaced soon. I’m wondering whether to just let my MacBook die out fully and buy a new one or to just buy one now since now I’m starting uni. I also wanted to know which MacBook is better the air or pro? I’ll only need it for assignments, watching videos and maybe here and there editing as I do YouTube on the side as a hobby
