I’m mulling over whether to upgrade from Sierra to Mojave and have read the various opinions of people on here. There are a couple of things which I’m uncertain on – any advice/clarification would be most welcome: 1 - As I’m currently on Sierra (not High Sierra), I assume my file system is HFS+. I know nothing about this system or the APFS one, although if I upgrade to Mojave it will be APFS I understand. I’m unsure of the difference and – if I do upgrade – will I notice any changes to the documents currently stored on my Mac? 2 - I appreciate that the Mojave GM version has only just come out, but does anyone have any idea on when the .1 update is likely to be? I’ve only had a Mac for a few years and am unsure when this could be. Thanks and apologies if these matters have been covered elsewhere on here.
