Advantage of cloning the MAC Address?

What's the advantage of cloning the MAC Address?
Solved!
Go to Solution.

There is no "advantage" of cloning the MAC address. The only advantage would be to have internet or not.
In many cases, it is absolutely unnecessary to use the MAC address clone.If you have a working internet connection through your router then there is no need to use the MAC address clone function.
Only when you find that you have a working internet connection on one computer directly on your modem but not when you connect through the router (or a different computer directly on the modem) then it is necessary to use the MAC address clone function.
This usually is only the case with cable TV ISPs. They only allow you to have a single active internet connection at any time. They do this by remembering the MAC address which connects through a specific modem. If you first connect a computer for tests directly to your modem you'll have an internet connection. Now if you connect a different device to your modem it doesn't it's because the ISP has still locked the internet connection for the MAC address of the first computer.
How to remove the lock depends on the ISP and the modem. Sometimes it's enough to reset the modem or to power down everything. Sometimes you have to power down everything for a few hours and after that the first connecting device is the one with the internet connection (i.e. make sure to connect the router then...) If you want to know exactly how your ISP does this you should ask them...
The simple workaround is to use the MAC address clone function. The router "clones" the MAC address of the first computer, i.e. it basically pretends to be that computer. The MAC address is accepted by the ISP and is immediately allowed to the network. You have a working internet connection either directly on the first computer or through the router because both use the same MAC address. (It's no problem on the router because the MAC address is used on the internet port only...).
Of course, you have to remember all this. If at some later time you connect a different computer directly to the modem (e.g. you have connection problems and you want to find out what's wrong) you may "lock" in a different MAC address for your connection and you'll have to wait again to regain the connection for a different device.
But again: there is absolutely no need to use the clone function if you have a working internet connection through your router.

I have a MAC Pro from 2011 currently running MAC OS 10.9.5. This weekend I cloned the MAC HD drive to a new SSD drive for improved performance. The clone was completed successfully with no errors. After the clone completed I successfully restarted my system using the SSD as the boot device. I then successfully tested all of my products, including Photoshop CS6 and all of its plug-ins. I successfully tested the key features that I frequently use. Today while attempting to launch Photoshop CS6 a message is being displayed indicating that a scratch disk cannot be found. All drives are available on the system via the Finder and Disk Utility. I can access all drives including the old MAC HD which is no longer the boot device. I've even attempted to launch Photoshop from the old device yet the same error persist. Is there a way to review/edit/change Photoshop preferences if Photoshop doesn't launch? I've even restarted my system several times to see if that would resolve the issues. Does anyone have any recommendations for this issue? Have you previously address this issue?
Thank you Gregg Williams

I need to change the MAC Address for Airport on MacBook

I have a specific need to change my son's Airport MAC address as his school requires the use of USB network cards that aren't compatible with MACs. These cards are needed because the school's router uses MAC address filtering.
Before we upgraded his Mac to Snow Leopard, we were able to change the MAC address to the MAC address of the useless dongal the school supplied. We basically created an AppleScript program that ran the "sudo ifconfig en1 ether xx:xx:xx:xx:xx:xx" and all was good.
This command no longer works for changing the MAC address. We tried it as root user as well and by typing it into the terminal window as root. After running the command, we can run "ifconfig en1" and it does display the new mac address but when we turn the airport on and try to connect, it just hangs and won't connect.
Our other non-Snow Leopard still works fine after running the commands so I'm guessing Apple disabled this functionality. It's hardly a security issue by being able to change your mac addres.
Is there a new way to accomplish this? I've searched everywhere.
Thanks!

Would an easier solution be to provide the school's IT admin with your mac address and have it added? If they can add a block of mac addresses for the usb dongles, they can add more for machines that cannot use the dongle.
Also: "It's hardly a security issue by being able to change your mac address."
While it may not be a security issue for your machine, it is a security for the school network who is using mac address filtering as hopefully only one part of their wireless security.
That being said, have you read this?

How can I get the MAC address of my Apple TV?

How can I get the MAC address of my Apple TV? I currently do not have an HDMI device to connect it to, and the MAC is not listed on the box or the Apple TV itself.
(to answer the obvious, I am trying to pair it with an iPad, and I need to register the Apple TV for the network so the two can see each other)

As long as I know java doesn't have support to work on link-layer, only internet and transport layers. You may write simple native code. On windows, IP Helper functions, like SendARP allow you to pass an IP address and get the hardware address. You store the hardware address on your database/file and later, when that machine is off, you send a frame to the address you stored previous.

Is there any way to track a stolen laptop using the mac address, or by triangulating the wifi, or even by checking to see if the macbooks serial number has been registered online anywhere?

A little info on my question,
I had it stoeln on June 22nd 2013. I had recently bought it so had not installed any software on it nor did I have registered with icloud. I had contacted police, registered it stolen with Apple (but then just discovered this week that apple do not have a database for stolen products, which makes no sense at all).
I have contacted all the major pawn shops and computer stores in town etc etc. I have recently discovered that each laptop has a unique MAC address whcih begs the question, is that traceable somehow? I have been made aware that the router strips the mac address before it connects it to the internet but does the isp log the laptops MAC address? If i contacted all the major isp in my country would they have the ability to search for the mac address of my latop and then link that with an ip address?
Any help would be great please!

Yeah but I registered it stolen with Apple first thing, then called local police etc. Apple told me on the phone that the serial has been logged as stolen, which I assumed would limit the computers use online.
Every machine has a unique serial number what I was getting at is there must be some way to track the serial number and for example if the theif logged onto facebook using a stolen machine, if there were a register of stolen equipment then red flags would pop up, you know what I mean?
Well, I hadn't heard of that before. If it's true, then what you say should also be true but the Mac would have to publish its hardware serial number over the Internet and I haven't heard of that either. The only Apple tech that is supposed to constantly track you is iCloud.
You said you assumed the database would limit use online but if that's only an assumption, you need to ask Apple what exactly the stolen database does. It is possible that the serial number might only get flagged if it comes into an Apple Store for service, if it ever does. You need to clarify this with Apple.

How do I find the MAC address of a CLIENT ACCESS POINT created from the FILE SERVICES ROLE

I have several Client Access Points created within the clustered File Services Role. The only way I seem to be able to determine the MAC address of each of these, is by visiting the DHCP server.
Does anyone know if there is a way of reporting on this from the server (active node) itself? I have tried ipconfig all, checked the properties of the CAP in the FCS console etc.
Many thanks.

Hi,
As far as I know there have no original option for query all the CAP MAC address, may you can create a PowerShell command then filter the configuration result, you can ask
in PowerShell forum for the further help.

How do I find the MAC address of a paired bluetooth device?

I have just connected a bluetooth device to my MacBook. When it was pairing, it displayed the MAC address of the device, but a few seconds later, the MAC address was replaced with a test description of the device. I need to figure out what that MAC address was.
For clarification, this is not an ethernet connection, it is Bluetooth. The device is a type of headset, it has no use accessable interface, and no the address is not on the device itself.
Thanks,

My MacBook was stolen and I need to know the MAC address

An emergency question to Apple support. My MacBook was stolen and I need to know the MAC address of its network card. I have a receipt with the serial number of my MacBook. Can you assist?
My serial: W8***66D
Thank you
p.s Any ideas how I can find it?

Report the theft to your local authorities.
Apple has no means of tracking thefts, as thieves themselves may claim the machine is theres just by looking up the information on the computer, and unless you registered the machine, it is really their word against yours, unless you also have receipt or other information that they can track to your receipt against your serial number.
Your homeowners insurance may be able to recoup the cost.
In the future, consider getting Lapcop, or Lojack for notebooks.
Good luck!

On windows XP or linux have a MAC adress Change function allow 00 mac adress and another normal mac adress range.On windows 8.1 all Mac changer program dont work.This 2,6,A,E on second adress are not vaild Mac adress. You simply can not use normal MAC
addresses on windows 8.1.When i connect the usb the Pc windows 8.1 recognizes the adapter but the default driver and the downloaded ralink driver the same problem.On windows xp the current driver works perfectly have (Local Mac Network Adress) funktion
and works with the 802.11b hot spot.I got the internet my PC and laptop too public HotSpots and another wifi HotSpots if wont work correctly i can not use neither the windows 7,8,8.1 or 10. Many users have expressed interest in the problem more forums.
The 3. problem im tested in virtualbox the windows 7 and 8.1 on 8.1 (on the blue wifi platform) not show correctly the signal strengh. On windows 7 show this correctly.The windows 7-8.1 Configure/advanced the advanced options on Ralink 3070 the default (windows
driver) somehow downgraded function is less than for Xp. Configure/advanced the advanced options (needs to be upgraded in the future) because it does not advance but rather regressed.
Today it is very common these wi-fi technology increasingly used (hotels,Public Hots Spots,Internet coffe,) growing free bublic wifi projects. The wifi funktions on windows need debugging and modernize.The quality of Wi-Fi is now the operating system

Hi,
For changing the MAC address for Windows 7 is designed with some limitation, we cannot get over it. Thanks for your understanding.
Under Windows 7, the possible range of spoofed addresses for wireless adapters that can be set is limited. To be used by Windows 7, a spoofed MAC address should have 0 as a least significant bit (unicast) and 1 as a second least significant
bit (locally administered) in the second nibble. Thus possible values for the second nibble are limited to 2, 6, A and E.
In other words
MAC address: “XY-XX-XX-XX-XX-XX” “X” can be anything hexadecimal. The hexadecimal “Y”, written in binary format, is Y: “kmnp”, where “p” is the least significant bit;
p=0 --> unicast;
p=1 --> multicast;
n=0 --> globally assigned MAC;
n=1 --> locally administered;
So, actually MAC can be changed to any combination in which p=0 and n=1;
“Y” can be 2, 6, A or E.
So the possible MAC addresses in Windows 7 for wireless adapters:
X2-XX-XX-XX-XX-XX
X6-XX-XX-XX-XX-XX
XA-XX-XX-XX-XX-XX
XE-XX-XX-XX-XX-XX

Hi Bruce,
Out from what I can find on this network card is it not possible to get the mac address without a OS. I would recommend you to get/burn a Linux/Ubuntu live CD/DVD and run a Ifconfig in there.
Hope it helps you.

Can I get the Mac address in Audit logs of Active directory server for the user's machine which connect to the network/Domain

Hello All,
I am trying to get the information of all the user's who connect to our Domain network by signing in using the domain account. For this I am using the Windows audit group policies ( I am not sure of there is any other way). I can see when the user tries
to login to the network there is a audit event created on the AD/DC server. I can see the Kerberos authentication and logon/logoff events in the audit events under event viewer.
However the info which is being populated in these events include :- Hostname, IP address, Username and so on... But I can't see the MAC address of the user machine/system. Is there any way I can
get the Mac address of the endpoint system as its one of the important criteria for our project.
Any inputs on this would be appreciated, incase if there is any other way other than group policies please suggest.
Thanks,
Kavish

If you use DHCP, you can query the DHCP server. There's no builtin
method to get the MAC address directly.

How to get the MAC address of a PXI in a dll

Hi,
I am looking for a way to get the MAC address of a PXI RT controller. I know that there is a VI to do this, but I am looking for a solution for a dll (C-Code).
I use the "Call library node" to call this dll and want to make sure that it is only used on a specific PXI.
Since the VI provides the functionality, I am wondering if it is also available to be called from C-Code?
Thank you,
Christian

If it is available in LabVIEW it is probably available in CVI, which you could then build into a DLL (if there isn't one available already).
