So I have an opportunity to get this from an authorised store in my area...at a good discount. https://everymac.com/systems/apple/...arly-2015-retina-display-specs.html#macspecs4 The ports on it are the main reason as I do not ever want to be fkin around with dongles. My usage does not need the fastest and greatest....just word processing, interwebz light video watching. So please, no lectures on get the latest it'll hold its value....i don't upgrade often....plan to get at least a good 5-7 years use from it. Plan to keep it on el capitan for as long as possible. Question Im asking is....can I swap the 128GB SSD with a larger one from the market. AND WHICH ONE TO GET? Samsung is preferred. I have no idea whether to get a NVME drive or something else....nonroom for error as I won;t be able to return it. Does it need an adaptor? and if so does anyone have a link to which one specifically?
