Can't apply 2018-001 security update

I installed macOS using corpnewt's guide and most of my setup works, but I can't install the 2018-001 security update: each time I try, it ask me to restart my computer at the end, but when I do the App Store keep showing me this security update as not installed. My downloads stick after reboots so the hack doesn't start "blank" each time, but because of this I can't install the Nvidia Web driver (my macOS version is not compatible).
