If you have Homebrew, install SpoofMAC with

brew install spoof-mac

You can also install SpoofMAC with pip, or directly with:

git clone git://github.com/feross/SpoofMAC.git
cd SpoofMAC
python setup.py install

Add a local.macspoof.plist file in /Library/LaunchDaemons:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
        <dict>
            <key>Label</key>
            <string>MacSpoof</string>    
            <key>ProgramArguments</key>
            <array>
            <string>/usr/local/bin/spoof-mac.py</string>
                <string>set</string>
                <string>ca:fe:ca:fe:ca:fe</string>
                <string>en4</string>
            </array>   
            <key>RunAtLoad</key>
            <true/>
</dict>
</plist>

Adapt the interface name and address to your need then reboot.

Then load the launch daemon:

sudo launchctl load /Library/LaunchDaemons/local.macspoof.plist

P.S.: There is a similar question Change MAC address in OS X Yosemite but the question is not about permanent change and is only for Yosemite.
