Apple has removed the download links on their Support page to Security Update 2019-004.

https://eclecticlight.co/2019/07/25...-for-sierra-and-high-sierra-security-updates/

Security Update 2019-004 for Sierra and High Sierra may cause problems with sleep. Either activating or waking up.

Already mentioned on Macintouch and above website; MacRumors, AppleInsider, MacObserver totally mute about this MAJOR issue. MacSurfer News points to above website.

Edit: Appears to be related to BridgeOS update for T1, T2 chips..
Mostly 2016-2018 MacBooks, MacBook Pros, and Mac Mini 2018s affected.
