    Security of High Sierra with Latest 2019-003 update vs Mojave 10.14.5
    Hi Guys,

    I'm currently looking at the prospect of doing a full HDD erase and clean USB install of Mojave (ideally 10.14.5) using a bootable USB (offline installer), but am interested to know whether I will have higher security after going through all the effort.

    Is High Sierra with the latest security update (2019-003) equally as secure as Mojave 10.14.5? I recall reading that Mojave has in built protections such that permissions are required before any app accesses the system microphone etc. Are these the kind of features that even a 2019-003 High Sierra security update won't provide for meaning that Mojave is the better/more secure choice?

    Hi and welcome.

    Most of your questions, maybe not all, have been addressed in your other post: Offline Mojave Installer

    If there are outstanding issues, please advise.

    What Mac are you going to do this on? MBP, iMac, MBA, Mini, MB or Pro? What year is your Mac?
