My new 2018 MBP shipped with High Sierra, which is what my old 2014 was using. For reference, I was on Yosemite until very recently because I am always reticent to update while working on major projects (I work with music technology, and rely on a lot of third party software and hardware on a daily basis). I'm considering just leaving the machine on High Sierra, since I know everything works there. Is there any reason why I should think about moving to Mojave? Is there something I'm missing?
