One of the reasons I'm not on HS yet.
They've had support issues as well (Serato just released their latest version, which is compatible with HS).
In truth, if properly setup, users should be creating a password for their root accounts, which would avoid this problem. This is no different than using an Admin level account (which is root) on Windows as your daily account and with either no password or autologin - and this happens EVERY DAY.
'researchers confirm—that it's possible to block the attack by either setting a password for the root user, or disabling root access altogether' - similarly stated for MS, this would be 'researchers confirm—that it's possible to block the attack by either setting a password for the admin user, or disabling admin level as a daily use account'.
One of the differences is that Mac has 3 levels of security, while MS only has 2. The Mac has general users, system admins and then root. MS has general users and admin (root). From a security aspect, unless needed, root should be disabled on Mac's - and by default, is a hidden account to protect it from users using it as their everyday account.
In any environment, security is only as strong as the weakest link.
