in another thread i've found this alternative to en0 ether xx:xx... :
sudo ifconfig en0 lladdr 00:00:00:00:00:00
but i remember trying it without success, anyone has a clue how to change the MAC address in leopard? on top of it - why on earth would they downgrade a system? is this one of these 300 new features? sweet :P

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,
str4ngS

Yes, 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.

Changing MAC Address

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.

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.

My MacBook Air lost mac os x. So I would like to reinstall mac os. But I can't select the disk to install mac os x. Only Recovery HD is shown and I can't select it. How can I reinstall my Mac os x.

you can download the mac os x recovery hd and run the setup to a flash drive using another mac computer running os x 10.7,(so that while installation the os x setup can varify your computer's serial no. and provide you the installation setup through internet)
or the time machine backup(if you have)
Now boot through the flash drive and follow the steps to install mac os x
here is the link to download the recovery hd for flash drive

Whenever I start to sign in (MSN Hotmail), previous addresses come up that start with the same letter as mine. I would like to clear them out so that only mine comes up

Problem summary: Whenever I start to sign in (MSN Hotmail), previous addresses come up that start with the same letter as mine. I would like to clear them out so that only mine comes up.
In a different help forum someone told me that the autocomplete (autofill) feature of my browser is enabled. Seems that it is set to save autocomplete data for forms and/or usernames/passwords. I need help with the steps necessary to disable this feature.

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

There are some wifi-enabled drives that allow you to stream content from them to the iPad e.g. GoFlex Satellite and Kingston Wi-Drive - I haven't used any so I don't know if one is better than the other

My MacBook Retina has been shutting off multiple times per day. It is beginning to happen more frequently. What can I do to locate the exact issue? My warranty has expired so I would like to get to the bottom of it without taking it in to an apple store.

I am currently learning how to do diagnostics on mac hardware but I am not a native mac user. It is unlikely that this is a software issue. Please, any input will be helpful.

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
     after the chime press and hold down the OPTION key until the boot manager screen appears.
     Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
     Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
