macOS: Useful Commands

The intent of this page is a quick reference of some interesting and useful commands.  The following commands had been tested against macOS versions 11.5.2+ .

Serial Number

ioreg -rd1 -c IOPlatformExpertDevice | awk -F'"' '/IOPlatformSerialNumber/{print $4}'

Model Number

sysctl -n hw.model | cut -d "," -f 1 | tr -d '[0-9]_'

Current logged On User

ls -l /dev/console | awk '{ print $3 }'

Change Computer Name

Note: ComputerName works with FQDN.  The LocalHostName did not like the .local (as some sites would suggest).

hostname "$computerName".domain.com
scutil --set ComputerName "$computerName".domain.com
scutil --set LocalHostName "$computerName"
scutil --set HostName "$computerName"

Display names of all local users

I have added the '-x' otherwise, any domain user that begins with uid 5XX will be displayed.

dscacheutil -q user | grep -A 3 -B 2 -x -e uid:\ 5'[0-9][0-9]'

Add SecureToken access to user

sysadminctl -adminUser <LocalAdminAccount> -adminPassword - -secureTokenOn <user> -password -

Domain User.  You changed a domain user account group access and want it to propagate quickly.

exec su -l $USER

Add color to vim, edit ~/.vimrc

syntax on
