Changing MAC address at the boot time
I want to call "ifconfig eth0 hw ether (...)" before dhcp client starts. Is there any place in the network scripts which already does it or should I add it anywhere I want?
Hi,
According your description, this may be caused by virus or malicious client.
Please try to perform a network capture on your DHCP server. Then find the device which send these malicious discover messages.

To prevent this issue, you may implement NAP Enforcement for DHCP.
Here is a checklist of configuring NAP Enforcement for DHCP,

DHCP Server with the strange MAC address at the same time. This MAC address is HEX IP address!
Server version: Windows server 2008 R2 Ent.
Structure of DHCP scopes: Two DHCP server 50% to 50% all allocation for per scopes.
Question: Sometimes the DHCP server
allocate the IP address at the same time to the a strange MAC address per IP address, the type is "DHCP/BOOT", it cause DHCP scopes out of space at some time point. We need clear up them manually.
I found strange MAC address in HEX is the IP address which the server allocated.
Someone meet the issues before, any solution for this ?
Thanks !

AddressBook - Is there a way to change multiple addresses at the same time?
To be clear....I have 25 contacts at 1 company and that company moved.
Is there a way to link the cards together so that when I change the address on one card it automatically updates the other 24 cards?? Rather than having to change each contact individually, which is time consuming and annoying.
I have created a "Smart Group" for the company and all of the contacts place themselves in the group but it still won't sync the addresses.
Can someone tell me how to do this, if it's even possible? And if it's not, I really wish it was!!
Thanks!Open your Photos App > Camera Roll > At the top right corner you will see a rectangle with a right arrow, select that. Now you can select as many photos as you want and you can hit the red Delete button on the bottom right.

Probably incredibly simple question, so sorry. I have just changed e-mail after many many years and I want to e-mail everyone in my mac mail client with the new e-mail address at the same time.
If you are using Address Book, open it, create a new Group, select all you contacts by click the top one while holding down the shift key and then select the last one. Drag the contacts to the group, then send an e-mail to the group.

How to change mac address on time capsule
Hi there,
How to change mac address on time capsule?There are routers that allow you to create/clone a mac address to whatever you like. Since many companies use the mac address to 'register' a unit connected to it's system, you usually just have to let them know you've changed your router and they will reset your system to accept connections from the new device.

Why is the boot time on my mac pro 2010 slower than my 2010 core 2 duo 13 mbp?
Why is the boot time on my mac pro with clean install of lion around 34 sec on my mac pro 2010 2.8 quad core, when it is only around 17 sec on my 13 mbp 2.67 core 2 duo?
The mac pro uses around 13 seconds from i hit the power button til i hear the chime and see the grey screen.
Is it because it uses time to find the wireless keyboard, trackpad and cinema display?
Mac pro has 16 gb ram and 240 gb ocz agility 3 ssd, macbook pro has a intel 120 gb ssd (320 i think) and 8 gb of ram, so the mac pro has more umpf....Well it might take a little longer since POST (power-on self test) needs to check more memory.
But try doing a smc and pram reset and see if that helps. -
i just did something on my mac and now the date, time and battery percentage are in arabic and it says lebanon (arabic) in the language and text preference, how can i change it back to english?

How do I find the MAC address for the time capsule?
I am trying to install 2T time capsule as my main router. Telus my internet supplier allows me to in install the MAC address for the static ip that I am going to use. But where is the MAC address on the cube or how do I get it?
On the bottom label it should list the MAC address.
If you happen to still run the original.. ie decent airport utility it has all that info right in front of you.
But you see that was before Apple reduced the airport utility to the status of a toy..
Pretty pictures no info.. think kid's book.
See very very pretty.. as a UTILITY though.. useless. -
Can't change MAC address of my wireless card on Windows XP
Dear Forum Members,
I have recently bought a notebook, Lenovo IdeaPad G550L (I haven't found section for the G series here on the forum) and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly changed MAC address. I installed the recommended driver, available from Lenovo's website, version 5.10.38.14. I tried the common way to change the MAC address, went to Control Panel -> Network Interfaces -> Broadcom Wireless Network Adapter -> Configure... -> Advanced -> Locally administered MAC address, and changed it to a different address (without ":" or any separator characters). Unfortunately this common solution won't work at all. Although, no error messages are produced when changing it (so it seems successful) my wireless router shows me the original MAC address of my integrated wifi card. Tried to restart my computer, my router, everything.
* Tried different drivers, downloaded a driver from HP which had a separate wireless configurator, Broadcom Wireless Utility. It worked like the driver from Lenovo (except this one hasn't got the utility), but I was still unable to change my MAC address.
* Tried a different driver from SoftPedia, version 5.10.79.14 (this is newer than Lenovo's), it didn't work either.
* Tried Nathan True's MACShift utility. It seemed to change the MAC address, but my router showed the original, so it didn't.
* Tried to look for official Broadcom drivers on www.broadcom.com but found nothing for BCM4310.
* Finally, I booted my alternative OS, the latest Ubuntu Linux, and used the kernel driver b43 for my wireless adapter. I tried to change my MAC address using the command ifconfig wlan0 hw ether .... and connected to my network. It worked, my router showed the changed MAC so the hardware (or the firmware) is capable of doing this by the right driver/firmware.
I tried to address Broadcom with the issue, sent them a letter like this post they replied that they are not competent, they wrote the following (I guess this was an automatically generated message because it got back in 10 seconds ) from [email protected]:
"As the chipset supplier, Broadcom provides driver support to our customers - the manufacturers of wireless devices - that ultimately provide products to end customers, such as wireless LAN vendors, cable modem vendors, and notebook providers. It is up to these manufacturers to provide product-specific drivers and software support to their end customers. Please contact the manufacturer of your wireless device for their current drivers"
Then I addressed Lenovo with the problem, their answer:
"Dear ******,
Thank you for contacting Lenovo, the makers of ThinkPad and ThinkCentre products. As I understand, you have purchased a Lenovo IdeaPad G550L and would like to use its WiFi adapter (BCM4310 according to Everest) with explicitly change MAC address.and you would like to know is there an official driver for Windows XP that allows you this basic feature like b43 in Linux. We apologize,Please do speak with our Idea pad technical Team at 877-453-6686 Option 1-2-1-2 for further assistance.
If you have further questions or concerns, please feel free to contact us at 866-42-THINK (84465) option number 2. We will be happy to assist at that time.
Once again, thank you for contacting Lenovo.
Sincerely,
Lenovo Websales/CustServe"
So this means I should call them and spend extra money for phone bill of international calls because of their fault of providing a basic feature that is to be expected from every single wireless card in the market. Should I believe that a guide over the phone is more efficient than a step-by-step solution or a link to an alternative driver? I'm getting kind of disappointed. At least they have understood (or copy-pasted) my problem, dutch comfort though.
Any ideas? Anyone experienced the same problem and solved it? Is there an official (or even unofficial) driver for this device for Windows XP that allows me this basic feature (like b43 in Linux)?
Thanks in advance,
str4ngSYes, I have posted this thread to different forums after I realized that Lenovo "customer care" is not likely to help me out and even wirelessforums.org members couldn't come up with any ideas for days, that's why. I have already written that helper applications like SMAC (or etherchange or macshift) don't work, because they do the same thing in the system as I change it in the driver panel, so they use the same method which simply does not work.
Locked? Definitely not. If yes, why can I change the MAC of my adapter under Ubuntu Linux using b43 open-source driver if it's really locked? Or you mean it's locked from software, because Lenovo or Broadcom didn't want their users to change their MACs or they just forgot to release a fully-functional driver? Well, then I would like to have a driver in which it's not locked, because this is a basic feature of my adapter of which the hardware is capable.
I have already contacted Broadcom, see their (automatically-generated) answer in my initial post, but I will try to do that again with more foresight. -
help! i actually have the same issue after disk recovery with mavericks, i changed my system drive to ssd. everything else works perfectly, but the boot time is more than a minute.
as soon as i press the power button, the sound goes, and a black screen will stay for about 10 seconds, then the white screen appears and lasts for about 45 seconds and as soon as the apple logo comes, it takes about 10-15 seconds only. I tried everything from resetting NVRAM and SMC, indicating the ssd as the startup disk, (i thought that would solve the problem for sure) and the like. everything works perfectly except for the boot time which is much slower than my original 7200 rpm drive.
i really do not want to do a full reinstall of my software because initializing would probably take a day or two, and i have lots of deadlines. is there something else i can try?
i'm using a mac pro 4,1 (early 2009) and using mavericks 10.9.2. 16 gb ram
<Subject Edited by Host>Are you speaking of a Mac Pro or a MacBook Pro? A 4,1 MacBook Pro can handle up to 6GB of RAM. I don't know about a Mac Pro - the is the MacBook Pro forum. If you need information about Mac Pros, see -> https://discussions.apple.com/community/desktop_computers/mac_pro.
Good luck,

Changing Mac Address/Static ip
I recently bought an New iMac and Migrated everything over from my old mac.
However I mistakingly migrated the Static IP address or MAC address from the old machine too!
This is now giving me problems when trying to connect both machines to my network via Ethernet!
My wireless access is fine, but ethernet is saying ‘no ethernet cable is inserted’ on both machines now. The cable is in and works fine on other machines.
Do I need to change the MAC address on the machine?
If so how?Hi
System Preferences > Network > Select the interface > Advanced > TCP/IP. Have a look at both macs to see what they're using. Change one of them.
You can't change a MAC address unless you know how to spoof it or if the NIC hardware has changed. The MAC address is not your macintosh IP address. In this instance MAC stands for Media Access Control. It's the unique ID number given to a network adapter. No two are the same, leastways they should not be. If you want to view both your macs MAC addresses. Apple Menu > About this Mac > More Info > Network. Select the interface you're interested in.

Changing MAC address on wrt300n
So what did I learn today ... never let your little brother on your PC when logged in at a forum ! Result = kicked out, profile deleted, IP banned !
So I gather that my ISP has only static IP's and they suggest to change my MAC address to get a new IP so I can return to the forum and sign up again with a new profile. So the question is ... how the heck do I change the MAC address on the router ? Anyone have a source that I can read up on this ? This is all very new to me.
Thanks in advance.MAC addresses are like DNA. There are no two matching ANYWHERE in the world (each device in the world has a unique hexidecimal MAC address and no two are alike). Therefore you cannot change your MAC address.
What I can tell you is what your ISP really means. When you connect your router (which has a MAC address) to their modem, their modem memorizes your devices MAC address and assigns it an IP address. You need to make the modem forget this MAC to get a new IP.
To do this, turn off your modem and old router and leave it off for a bit (10 min). Borrow someone elses router (or if you have an old router, use it). Connect it. Turn on modem and new router. Leave on for about 15 min so that your ISP forgets the old MAC address of your original router and creates a new IP address under the new MAC address of the newly connected router.
After 15 min, power them both down again, disconnect the temp router and connect your original router. Power them back up and wait 15 min again. You *should* get a new static IP from your ISP as it thinks it's a new MAC again. The ISP doesn't remember MAC addresses, only their modem does and once it forgets, it should give you a new IP when you connect the router again.
Hope this helps!! -
Recently i have been trying to change my Router's MAC Address. I have a WRT54g v.3. I have done it before where i had unplugged the internet cable going from the wall to the modem. I saw the change on the 192.168.1.1 status page. And i noticed with a proxy and the new changed MAC address i was able to get into gaming servers i hadn't been able to before because my IP was banned.
Now when i try to change my MAC address, it doesn't seem to change on the router stautus page like it did once before. I'm sure that it's possible to concel my identity of my old IP and get a new IP (through a proxy), many people do this for security reasons so i'm hoping linksys products can offer some kind of security by doing this.
btw, sorry about the name, if it's possible can it be changed to Joe. Thanks guys.Your MAC is "stuck" to that router, you need to spoof it. Google it.

I have just bought a Humax 7500T PVR and a Humax W-Lan dongle to connect to my Airport Extreme.
I have put the mac address into the AE. The installation screen on my TV is picking up the network name but once appied it won't connect to the internet.
I've a few other things connected to the AE such as computers, ipad, itouch, etc, and have never had a problem connecting these once I've entered the mac address into the AE. Can anyone help me with this please?have you made sure that the network setting in the system preferences is set up to use dhcp? if not i would try changing it so that it shows that it is getting its address by dhcp
