Macbook pro, black screen with chime only after using Casper/JAM Every time I boot the mac I get a black screen, I can hear the chime but that's it, nothing comes on the display even when having an external display connected. In recovery mode it works, i get display. 


tried NVRAM SMC resets
tried First Aid on the disk and permissions repair
tried deleting and recreating kernel cache
tried booting in single user mode or verbrose mode and both give me a black screen.  
tried reinstalling the OS which worked just fine UNTIL I join the laptop to the domain (using Casper/JAMF) and reboot it goes back to the black screen issue
tried fsck_apfs
If I understand your problem right ... it only happens after you join Mac to the domain using Casper/JAMF !

Try following.. hold option on boot and manually select the boot drive again while holding control to set it as default
