You can set a static ip address in OS X with the following command. Replace en0 with the appropriate interface.
sudo ipconfig set en0 INFORM 192.168.10.12
The default ethernet interface on a Mac is usually en0. You can run ifconfig to view all the interfaces available on the machine.
The ip address will last until you reboot.
You first need to boot your Mac into single user mode by booting it up while holding down the “command+s” keys.
Once your in Single User Mode type in
mount -uw /
That will mount your Mac hard drive. Now run
launchctl load /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist
and now you can change the password. Replace “username” and “password” with the username for the user and the new password.
dscl . passwd /Users/username password
Now you can reboot the machine
reboot
and log in with the new password.
The following command installs the .pkg to the local hard disk.
installer -pkg /Users/username/Desktop/package.pkg -target LocalSystem
You can also replace “LocalSystem with a “/” they both do the same thing.
If you want to install the package on a different disk you can change the -target to the drives path.
installer -pkg package.pkg -target "/Volumes/Macintosh HD2"
You can find more about the command by typing “man installer” in the terminal.
