sudo nvram boot-args=”-v”
After the next restart/reboot you will see the boot loading process when your mac turns on. To view the log file use the following command:
log show –predicate “processID == 0” –debug
To view just today’s data use the following command
log show –predicate “processID == 0” –start $(date “+%Y-%m-%d”) –debug
