Spoof Address On 2017 Mac OS X Permanently

I have question - how to change MAC address in Mac OS X permanently Ive tried using sudo ifconfig en0 ether 00:01:02:03:04:05, but changing the MAC address in this way is not permanent: after a reboot, it will revert to the MAC address physically stored in the card.

Any changes will be temporary and theres no way to do it permanently short of munging around with the hardware.

Caveat, I havent learned launchd, only have been familiar with rc.boot and rc.local type config files, so maybe this wouldnt work.

Apple sure doesnt seem to like supporting MAC address changes, you cant do this on Airport base stations either.

The system was designed this way to eliminate the possibility of 2 pieces of equipment from having the same MAC address.

I believe that you cant permantly chage any MAC address on any piece of hardware that has a nic interface.

Will they work and is it safe to use them Follow these steps to create a script that sets the MAC Address each time the computer restarts: 1.

Open Terminal (ApplicationsUtilities).

Type: cd Library 3.

Press Return. 4. Type: mkdir StartupItems 5.

Type: cd StartupItems 7.

Press Return. 10.

Type: cd MACADD 11.

Press Return. 12.

Type: pico MACADD 13.

Press Return. 14.

In the pico editor, paste in the following text.

Note: Removing the number sign () from the beginning of a line uncomments it.

Typically, en0 is the interface name for the Built-in Ethernet port and en1 is interface name for the AirPort Card.

To confirm that a network port is associated with a particular interface name, open the Network Utility (ApplicationsUtilities), and click the Info tab.

When you have finished customizing the file, save it (press Control-O), press Return, and exit pico (press Control-X).

Type: chmod 755 MACADD 18.

Press Return. 19.

Type: pico StartupParameters.plist 20.

Press Return. 21.

In the pico editor paste in the following text.

When prompted, enter your password.

Press Return. 28.

In the pico editor, add this line at the bottom: MACADD-YES- 29.

Save it (Control-O), press Return, and exit pico (Control-X).

When you restart the computer, MACADD is set for the interface that you specified.

Notes 1. The MACADD will be reset after changing a Location, waking the computer from sleep, or changing the state of the network interface.

To use the script again without having to restart, enter the following command: sudo SystemStarter start MACADD 2.

If you experience any issues or wish to not set MACADD during startup, you can turn off the new script by changing the MACADD line in etchostconfig to: MACADD-NO- Sorry, for a long post.
