The question is made because my 2015 macbook slowly will need a replacement. It served well for djing, video streaming as media server, live vjing, music making, recording sets, streaming with obs, doing some edits, music library management, and all other stuff not specially dj related. I can still run serato or traktor on it with no issues, but I know that upcoming new updates of some apps will become more Power hungry eventually… so upgrade is needed.
