X11 Server (Quartz 1.20.4) not having security extensions

[Christopher Jones]

Hi,

I am not an expert on this, but my understanding is this was intentionally disabled by default by the Xorg server build system, when XACE was added. The MP port stays as close to the upstream defaults as it can.

That said, adding an optional variant to enable this, if the user wishes to, seems an option.

please give the update there a go and report back to the PR if it works for you.
