How to change mac address on mac

i'm sry i'm not sure if this is the right section or not but yeah.... nyways does anyone know how to change mac address on a macbook?

If you have not updated your OS you can use the following command.
sudo ifconfig enX ether xx:xx:xx:xx:xx:xx
You will need to replace the X with your network number and the xx:xx:xx:xx:xx:xx with the mac you want to have.
Then run
sudo ifconfig enX down
sudo ifconfig enX up
This change will last till your next reboot.
cheers
NOTE: This is not working in 10.5

  • How to change enthernet address into mac

    i wana change my enther net address how i can change any one tell me .......
    i have install mac os x snow leopard 10.6.8

    Ok now i understand. Well, there is an easy way to do it, but it is only available for OS X 10.7and previous version, anyway here you have the link because they will support 10.8.* in a near future.
    https://github.com/halo/LinkLiar
    Now, the "not so easy" way depends on your experience with terminal consoles, but anyway it is easy to do it.
    Follow this steps:
    1- Open System Preferences
    2- Open Network
    3- Click on your Ethernet connection
    4- Click on the Advanced... button
    5- At the bottom of the window you will see your MAC address (Ethernet Address: xx:xx:xx:xx:xx:xx) write it down in a text file and save it, just in case you need to set it back.
    6- Open a Terminal window
    7- Login as superuser (root) in your terminal by typing:
    sudo -s
    If you didn't set a password for your root user then type your user password
    8- Now that you are a superuser type:
    ifconfig en0 | grep ether
    I am assuming that your ethernet interface is en0 because this is the Macbook Air discussion forum and that's the default interface name for the WiFi interface. The output from that command must give you a MAC address matching the one you wrote down in step 5
    If you are not sure what is your ethernet interface name just type:
    ifconfig
    and you will have a list of your interfaces. For me, when i connect my USB LAn adapter it is en2, you must check yours, and then just change everything that says en0 in these steps to your interface name.
    9- Now turn off your ethernet interface by typing:
    ifconfig en0 down
    10- And now let's change the MAC address by typing:
    ifconfig en0 ether your:new:mac:address
    11- Turn back on your ethernet interface by typing:
    ifconfig en0 up
    12- Check that you have your desired MAC address:
    ifconfig en0 | grep ether
    And that's all
    I'm not sure if this change will be permanent or if your MAC address will be rolled back to default after reboot. But now you now how to check it.
    Good luck

    How to change "home" address on IPhone 5s map app for navigation purposes

    OK I tried that.  I have two apps that need updating and it STILL shows the old Apple ID from the App store.  I even tried logging off iTunes and powering off the phone, then powering it back on and logging in.  Still shows the OLD Apple ID in the app store.  The correct one is showing in the Settings/iTunes.  Any other thoughts?

  • How to change billing address to another country?

    how to change billing address to another country?

    Before you change the country, you might want to note the following:
    1) If you have store credit, you must use the credit before you can change countries.
    2) You will need to download all purchased content. In addition, rented items must be past their 30-day expiration. For more information on rentals, please see:
    http://support.apple.com/kb/HT1657
    3) You must provide a payment method, such as a credit or debit card associated with a valid billing address in the new country. An iTunes Store Gift Card issued in the new country is also an acceptable payment method.
    4) After you change countries, you will no longer receive application update notifications in iTunes for the apps you purchased in your original country. However, you'll still receive update notifications on your iOS device for any applications installed on it.
    5) If you have an iTunes Match subscription, you can't change countries until the subscription has expired.
    6) If you have purchased a Season Pass, you cannot change the country associated with your account until that season is done airing and the last episode of the season has been added to the iTunes Store.
    7) If you have been using iTunes in the Cloud to download past purchases from your Purchased page, these purchases will no longer appear when you change the country.
    That said, you can change the country for your account using a computer using these steps:
    1) Sign in to the iTunes Store.
    2) From the Store menu, select View My Apple ID.
    3) Sign in with your Apple ID.
    4) Click Change Country or Region.
    5) Choose your new country from the menu, and click Change.
    To change the country for your account using an iOS device, check out this article:

    Check out the built-in Address Book Help guide on your Mac (in Address Book, choose Address Book Help from the Help menu.  I dont think you can change the way the address book looks in terms of changing its appearance to look more book like, but I could be wrong.  I checked out a few google searches and did not find anything that stated how to do what you are asking.  If you find you cant change it to your desired specifications, you can always make the suggestion to Apple: http://www.apple.com/feedback/

  • Can't add new MAC address to MAC ACL on Airport Express

    Hi,
    I just recently got a new iPhone 3GS. When I logged into my Airport Express to add it's MAC address to the ACL I found that the + icon was greyed out. I can modify old MAC addresses in the list and delete addresses, but I can't add new ones. Anyone have any idea why this might be the case. It seems like I can modify all other settings without any problems. I restarted the basestation, no help. I also even reset the password just incase, as you might expect that didn't help either. Any thoughts? Thanks.
    Setup:
    WDS with 2 other access points
    Mac Address Access Control set to "Local"

    If you are configuring the router as MGCP, you do not enter the mac address, just the router name.

  • WRT610N: Cannot enter MAC address in MAC address filter list

    My WRT610N cannot accept a very specific MAC address in any position of the MAC address filter list.  It is a valid address and it was working fine in the filter list of my WRT54G but the 610N will just not take that specific address!  What is this all about?
    Solved!

    I recommend to replace the WEP only device instead of taking the risk of a hacked network.
    And just forget about the wireless mac address filter. Anyone, who wants to crack your WEP network will collect enough accepted MAC addresses during the cracking process. It's just not worth the trouble to set up the filter and keep the list current...
    Thanks for the diligent follow-up gv but I can't replace the WEP-only device for now.  (I need to go through a conversion process for that device to accept WAP and that will take a fair amount of time)  I understand your point about getting accepted MAC addresses but, at least, it requires a bit more effort... Maybe I will return the WRT610 and stick with my old WRT54 until the 610 gets fixed...

  • Apple Airport Express: How To Change IP Address While in Bridge Mode

    Hello, I have a Apple Airport Express router and it has been good for a few years. Just wondering how to change my public IP address. I am also in Bridge mode to a cisco router. Also I am on a Windows 8 computer and this is mainly what I want to change the ip for.

    Power cycle the cable modem.. I presume that is what the cisco router is.. your modem.. if not tell us precise model and make of the modem.
    The public IP is not changed by you.. it is changed by your ISP.. normally if you power cycle the modem on a dynamic system you will get a new IP.. if not call the ISP and request them to make a change.
    It is never really necessary unless you got banned from a site.
    I am on a Windows 8 computer and this is mainly what I want to change the ip for.
    There is no logical link to needing a new public IP to being on a windows 8 computer.
    Explain more about your problem.

  • How to change IP addresses of APs and WLC to the ones from different VLAN

    I'm trying to figure out what is the best practice to change IP addresses on all my access points connected/managed by the WLC.
    I have one WLC2504 controler and three AIR-LAP1041N access points the idea is to change management IP of the WLC from 192.168.2.100 (vlan1) to 192.168.12.100 (vlan79) and all access points accordingly:
    ap1 192.168.2.101 (vlan1) to 192.168.12.101 (vlan79)
    ap2 192.168.2.102 (vlan1) to 192.168.12.102 (vlan79)
    ap3 192.168.2.103 (vlan1) to 192.168.12.103 (vlan79)
    FYI all my APs obtain IP from DHCP server which sits in the vlan1 and each AP is connected to trunk port on Catalyst switch, trunk port (vlan1, vlan79, vlan80, vlan81, vlan82) carries traffic for different WLANs, so my question is what is the best way to change management IP on each device with the minimal downtime.
    Thank you for your advice,
    Luu Manioro

    Well, you will have downtime anyways, but how I would do this is the following:
    Make sure the WLC trunk port has vlan 79 being allowed
    Change the high availability on each AP to point to the hostname of the WLC and the new ip address, you don't need the old ip address anymore
    Console into the WLC or use the service port and change the management ip address and at the same time if possible, move the AP's to the new vlan 79, since they have already joined the WLC, they will know of the ip address of the WLC
    Reboot the AP by shutting down the PoE port or powering off/on the AP
    The AP will find the WLC since you have defined the high availability and also since the AP and WLC are on the same subnet.

  • How to Change IP Address?

    Hi,
    I've a two node RAC working fine. I want to do an experiment and want to chang the VIP and private IP adresses. I canged the IP addresses in /etc/hosts files on bothe nodes and re-configured the eth1 with new IP addresses. I rebooted the nodes. When I try to start crs, I get error:
    CRS-0184: Cannot communicate with the CRS daemon.
    My question is that is it possible to change IP address of RAC nodes? If yes then what are the steps?
    Thanks.
