macOS Sierra on E6420

[macdev2000]

E6420, A23 BIOS, NVS 4200M 512, 128 GB SSD with Vanilla macOS Sierra Retail throws a strange show of checkers once it boots to login screen;

Boots fine through
-> Clover v2.3k_r3763 -> though it does takes some time to initd6, then ++++++++++++++,
-> continues alright till end to load NVDAStartup (Stock or WebDriver-367.15.1.0.05f01) with NVHAL100
-> Shows apple logo with progress bar and then instead of login screen this happens;

Seemingly the crux;

/var/log/displaypolicyd.log: AGDC support not present in system
/var/log/displaypolicyd.log: Policy Engine instance init failed

Ideas???

Use nv_disable=1. Maybe after install you can use the Nvidia web drivers.

Merci et apprécier.

Yes! With nv_disable=1 is how I installed it in the first place. Though then installed WebDriver-367.15.1.0.05f01 with clover boot args "nvda_drv=1" and/or clover config's <key>NvidiaWeb</key><true/> to shake it down. Yet still the same checkered screen whence OS X puts itself out of VESA into NVDRV. Seemingly the matter revolves around;
/var/log/displaypolicyd.log: "Policy Engine instance init failed".

Love to hear more ideas / solutions....
