Network mac address not present in OS yosemite

HI, I have a 2012 retina MacBook Pro (Retina, 13-inch, Late 2013), 2.4 GHz Intel Core i5.
I recently upgraded to Yosemite and can no longer see the mac address of my Apple usb ethernet adapter on the network setting on the system preferences application. Also, I can no longer see 'USB ethernet' in the network options. I only see thunderbolt bridge and thunderbolt bridge 2. Under thunderbolt bridge, i can see 'USB ethernet' as active but I can't see the mac address in the hardware tab. Anyone else have this problem?

Well, the explanation makes sense but I don't think it is true. I got to this thread because I have the same issue. I have hard wired my TC to my home network and set the Router mode in TC as Bridge Mode. Some days when I use the Airport Utility to view the clients it will show clients' names and the next day it will show the Mac Address. So, I believe it is a software / firmware issue.
I have turned off the wifi on my main router and all the devices are being connected wirelessly through my Time Capsules.

Airport Express WiFi network MAC address filtering not working

I have an Airport Express WiFi network which I bought and installed new in 2011. Initially I enabled MAC address access control and populated a list. It was working perfectly, I know, because a niece visiting tried to connect her iPhone and could not until I added its MAC address to the allowed list. Now however, anyone can connect without being added to the list. I think I read somewhere that a recent firmware update permanently disabled MAC filtering in Airport Express, even when it was previously working? Can anyone enlighten me about what's going on here?

In a sense those are/were/should operate as two separate functions, which they did before recently.
They do operate as two separate functions.....but it all depends on how you have the default rule setup in Timed Access.
If the default rule in Timed Access is set to No Access.......then a wireless device cannot connect....even it has the password for the network.....unless it has been setup on the list of allowed devices in Timed Access.
I have checked this 3 times this evening to verify. It works as it always has, and as expected.
If the default rule in Timed Access is set to Unlimited, then any device can connect to the network if it has the password. Devices that are listed or specified in Timed Access will be allowed to connect at the specific times that have been set up for each device.
So, if you want to use the more traditional MAC Access Control settings, the default rule has to be set to No Access and then you must set up a rule for each device that you want to allow to connect to the network. Only devices on the Timed Access list will be allowed to connect to the network. Other devices will not be able to connect to the network....even if they have the correct password.
If a recent firmware update has changed things from what they have always been.....then I am not affected....and I should be if I am using the same firmware as others.

ICloud registered to mac address, not me address

I originally got dot mac al those years ago and set up [email protected] (a)
then mobileme came along and I also got [email protected] (b)
I also set up two aliases with mobile me [email protected] (c) and [email protected] (d)
"a, c &d" all work fine on my iphone. but b doesn't appear in the from field wen sending mail.
Obiously as its linked to "a" by way of the same account I still get mail from "b", but I can't send from it, even when replying to messages addressed to "b"
Now my mac address "a" ended up getting signed up for a load of spam through a site that betrayed me so I don't use it anymore and all mails that come to it get atomatically deleted.
This poses a small problem when the iPhone wants to send all mail from this address.
I can choose "c" and "d" but neither of these are my primary email address. "b" is my primary address, the only one I can't send from on my iphone.
If I go into iCloud settings, the account is the Mac address and if I go into it I can't the apple ID from the Mac address, and down the bottom the Mail is the Mac address and if I go into that the address is the mac address and can't be cganged.
I set up iCloud with address "b" and it went back to the mac address.
If I go to manage my ID it has my primary email address as "b" but my ID is the Mac address.
I'd love to be able to delete the Mac address
To make things even more complicated, I can't send email from my Mac address from my Mac Pro, not that it matters, just shows its not all in sync properly, or so it seems.
So can anyone offer any help or tips or insight as to what I can do to fix this. I'v wanted for years to delete the mac address but I can't.
Thanks in advance

You can use either one.

Airport MAC address not set at factory?

I just received my new MacBook Pro and was getting ready to set my router so that DHCP requests from the new Macbook Pro would receive the same IP address on my home LAN.
The IP address for the Airport in my new machine is: 00:11:22:33:44:55 as determined by the following terminal command.
macbookpro:~ pderby$ ifconfig en1 | grep ether
ether 00:11:22:33:44:55
I tried to "spoof" the address with this command:
sudo ifconfig en1 lladdr 00:19:e3:d8:f5:07
which does not throw an error, but does not work.
Anyone else get a MacBook Pro where the MAC address for the airport was not set?
Any ideas on what to do?
I suppose I can just tell my router the MAC address is 00:11:22:33:44:55

Of course the MAC address and the IP address are two different things. I'm not sure why, Kappy, you thought I had this confusion. And I beg to differ, but MAC addresses are by interface, not by machine. So the ethernet port has a different MAC address than the Airport. They HAVE to have different MAC addresses or using two IP connections at the same time will not work when both ports are active at the same time and have the same MAC address. Using both ports at the same time with two independent IP addresses is completely supported by BSD Unix as well as OS X.
On my new machine the Ethernet Port EN0, has the MAC address 00:23:32:c8:27:4a
On my new machine the Airport Port, EN1, has the MAC address 00:11:22:33:44:55
I've had a lot of Macs, and this is the first time I've had an airport with this "default" MAC address.
My question is 1) does anyone else have a MAC address of 00:11:22:33:44:55 on their new MacBook Pro for the Airport hardware? If so, is this correct? Usually the MAC address has a manufacturer's Id embedded followed by a unique ID. 2) If someone is in the same situation have you talked to Apple about this? What did they have to say?
I can spoof the MAC address temporarily via the terminal, but it will reset to the hardware address on reboot.

Mail to my .mac address not being received. Mail to .me is.

Very Strange. Mail sent to my .me address is recived. Mail sent to my .mac address is not. Yet in iCloud I am identifed by my .mac address.

No, can't be done. Backups will occur when you are home if you are using Time Capsule, or when you connect your Time Machine backup drive.
Portable Macs back up locally, while awaiting a connection to your backup device. Try it yourself - you can "Enter Time Machine" and browse recent backups even when you are away from your Time Capsule.
Read about that here: http://pondini.org/TM/30.html. It has limitations - a consequence of sharing your local volume with TM's "local snapshots".
This feature can be disabled in Time Machine Preferences.

VNic Mac addresses not associated correctly when installing OVM Server

We are trying to get our first Oracle VM environment running and noticed that on the UCS the mac assocated with eth0 ended with 0B but on the Oracle install the eth0 interface mac address ends with 08. The mac for eth3 on the Oracle install lines up with what the UCS sees as eth0. How do we correct this and ensure the interfaces line up so that eth0 on the UCS is eth0 on the Oracle service profile ?

This is going to depend on how Oralce numerates the PCI BUS. That will dictate which PCI device the OS sees in which order.
You can try manipulating the order using a vNIC placement policy. This will allow you to ensure certain vNIC/vHBAs appear first on the PCI BUS for the host.

10.4.7 w/ 2 Wire Networking (Mac will not allow driver to see USB PC Port)

I've been using a 2 wire Networking DSL modem (AT&T/SBC) for years with no problem. Now with my new Intel iMac running 10.4.7 - the system will install the 2 Wire driver, but the new USB setting are wiped when the driver asks me to restart. Is there any way around this? It has completly shut down my DSL Internet system that untill now has been working flawlessly.

Maybe it's a good time to consider moving to a DSL router (wireless or not.) It is so much more cleaner solution... These days you can get a three-in-one box: DSL modem + 4port router + wireless access point.

SNMP data - MIB address not present

Hi,
My switch: CISCO Catalyst 2960-S (WS-C2960S-24TS-L V03).
I am trying to read some diagnostics data from the switch by using Kepserver Ex (SNMP protocol). I have downloaded the MIB files from CISCO site, RFC1213 and IF-MIB.
The problem is, that I can't read all the data. For example the OperStatus of the switch the server can read only for the first port (port no 1). For the other ports there is an information, that the address is inaccessible.
I have used the standard scanner (part of Kepware software) and i found inside the switch only one addres for OperStatus (1.3.6.1.2.1.2.2.1.8.1). Other addresses are invisible, for example there is no address for OperStatus port 2 (1.3.6.1.2.1.2.2.1.8.2).
How to deal with this problem, what can I do / change to read the data properly?
Regards

It is not necessary that port numbers has their index in order and port 2 would be accessible by # 1.3.6.1.2.1.2.2.1.8.2.
You can check the following command to see the IfIndex to interface mapping :
show snmp mib ifmib ifindex
Example :
Switch-01#show snmp mib ifmib ifindex
Loopback200: Ifindex = 92
GigabitEthernet1/32: Ifindex = 32
Vlan301: Ifindex = 187
unrouted VLAN 19: Ifindex = 145
GigabitEthernet9/8: Ifindex = 77
GigabitEthernet1/21: Ifindex = 21
Loopback1: Ifindex = 156
Vlan142: Ifindex = 184
GigabitEthernet5/1: Ifindex = 54
GigabitEthernet1/30: Ifindex = 30
Many times the index mapping can be random and port 1 can have snmp index as 1 and port 2 not necessarily may have snmp index as 2.
So from the above switch example, to see the operational status of Gig5/1 i will have to poll instance 54 :
ifOperStatus.54 (1.3.6.1.2.1.2.2.1.8.54)
Please check.
-Thanks

Networked mac will not share internet connection

When I connect my G4Imac to a Imacdv I can establish file sharing etc but the Imacdv is not able to connect to the internet via the G4Imac. Is this not possible or am I missing something? They are connected by ethernet ports but my broadband is by adsl speedtouch modem.
OSX3.9 on both machines

Hello and Welcome to Apple Discussions.
Go to  Apple Menu > System Preferences... > Sharing > Internet tab.
Now check the
"Share your connection from: Speedtouch Modem
To computers using:
Built-in Ethernet.".
Then click the "Start" button.
I used to do this but to my Powerbook using Airport. I assume that the Speedtouch connects via USB and has it's own driver installed?
kind regards

Device in Linksys Smart Wi-Fi is listed with two MAC address - not correct.

I am using a EA4500 and use Linksys Smart Wi-Fi to manage the device. In the household we have multiple Apple i devices. Somehow the Linksys Smart Wi-Fi combined two separte i devices (iPhone 5 and a 4th generation iTouch) to one user.
The devices actually have different names, but the Smart Wi-Fi is combining them into one device. So I can't use Parental Controls on one of the devices.
I hope you can help me on this. We have made sure both devices have different names.
192.168.1.106
F01:A9:95:67:17
192.168.1.122

Solved!
Go to Solution.

Before you decide to used the classic firmware, I would suggest that to try to manually add your TV under the DHCP reservation of the router's UI.

Networked Macs Not Always Showing Up In Network In Finder - On One Mac

The problem is that awake and running networked macs do not always show up in Network on the Finder. Sometimes they do and sometimes they do not. The problem happens fequently on one machine. Very similar questions have been posted on this. I suspect many are dancing around the same issue. I am hoping to get to the bottom of this.
All the OS X machines are running 10.4.9. Two are networked by Airport. The Airport and the problem iMac, an older G3, are wired to a LAN. On the LAN sits a PPC 7200 running OS9 IpNetRouter serving up IP addresses for all the connected devices, including printers. IpNetRouter also provides an internet connection out through a second ethernet card. The PPC 7200 drive is always reliably available for connecting to in the Finder.
Each of the OS X machines are set for Personal File Sharing only, with Firewall running, and without Stealth Mode enabled.
The problem is noticed on the wired Mac. Perhaps that is the key to this. The problem is not two way. The Finder on the wireless Macs shows the wired Mac in Network when the wired Mac is not showing the wireless Mac. Sometimes only one of the wireless Macs shows on the wired Mac. When that happens it is always the wireless eMac instead of the wireless Intel Mac.
When this problem occurs, it is always possible to connect to the "missing" wireless Macs by using their local IP address reported by IpNetRouter. It is not possible to do the same using the computer name of the Mac that should be visible in Network or by using its DHCP client ID.

No Macs are sleeping, but they might have been in the past. They don't show up when they are sleeping. These machines are often on for days. All are updated on a regular basis, including in the past two days.

Mac address - mac mini

does anyone know how to find the mac address[not ip address] for a mac mini? i need its mac address to connect to a network?

This solution is not applicable for Mavericks or Yosemite. If you are using either of these two OS do this: Go to System Preferences>Network in the left column choose the method you connect to network (e.g. Ethernet, WI-FI etc) click on Advanced>Hardware. This will show you your MAC Address.

DHCP and Pointers for Addresses Not Released

I was aksed to see if there could be anything to fix this:
Our DHCP hands out new IPs within a 24 hour period.
The Macs in our mixed environment ( 300 PCs, 52 Macs)
will get assigned an IP Address, and then keep it for the day, and in the morning release and get a new one at boot.
HOWEVER, according to the DHCP server, the IP address
still "points" to the Mac, and thus the DHCP server
thinks its in use.
Our IS department is convinced its a Mac problem,
and there has to be some way to make the Macs
release address, and tell the server its released
that address, so that the Server can re-assign
the address down the line.
I personally do not think so, I think it is something
on the DHCP server's end, but I'm not sure.
Any help on this or insight or general theorizing
would be helpful. I have also posted this over in
microsoft.public.windows.server.dns,
if this post seems familiar....

Backing up a bit - what is the actual problem leading
to this investigation? A DHCP server keeps a database
of pairings of IP addresses with MAC addresses (not
Macintosh addresses). It should automatically prevent
any MAC address from consuming more than one IP
address.
Most likely it is the fact that we have close to 400 total computers on site, and that we only have a limited available blocks
of IP addresses ( ranges 10.0.0.x, 10.0.1.x, and 10.0.2.x), and although at any given time not all 400 total computers
are on the network ( people out of house, some only go online
when necessary for updates etc), the fact that the DNS pointers keep saying that, for instance that an imac
on my desk is using 10.0.1.174, and that the DNS server is
saying that it should also be 10.0.1.146 ( which it had yesterday) as well as 10.0.1.174, but since the DNS server thinks
that 10.0.1.146 is still validily assigned, then it won't release this address, and thus on the PC side, they cannot
get the address 10.0.1.146, hich then causes a shortage of addresses.
I hope I explained that the best way possible; to me, it seems like it should be an easily fixed cache problem, if a cache exists for the DNS pointers, that it could be
regualrly dumped?

WRT160N V3 router ignores MAC address Access Restrictions, Filtering policies

I have added a list of 2 MAC addresses in the Access Restrictions for the access policy #1 and enabled it with Allow policy. But one of my PC's MAC address which is not on the list of access policy #1 still can access the internet and ping websites. I tried to add a Deny policy in 2nd policy for this PC MAC address and then it can not ping websites anymore.
The problem is why my PC with a MAC address not on the list of Allow Policy #1 can access the internet? It seems the router Access Restrictions don't work well.

I've already added Deny rule (blocking all LAN IPs) to all computers accessing my network in Access Restrictions Policy #1 but I leave one PC left to access the router web configuration.
Then in Acess Restrictions Policy #2, I added an Allow rule to one of my PC's MAC addresses (and its IP too) but the PC can not access internet and ping websites. It looks like the allow rule in policy #2 doesn't overwrite the Deny rule in Policy #1.

Where can I find the MAC address

Dear all,
Do anybody know in which scripts or files I could find out the MAC address (not type command line e.g ifconfig -a), thx a log!!
Regards,
Vincent

Hi Vincent,
<pre>
OK, Sparc systems gets its MAC address from NVRAM
and Intel (x86) systems gets its MAC address from
the ethernet card that they use. Since you had posted
this question on Solaris on Intel I presumed it to be
Intel.
Following is an unsupported and untested
method(atleast from my end). All the best.
You may try to change the MAC address using the
ifconfig command.
(ifconfig elxl0 ether x:x:x:x:x:x)
In this file, add the entry at bottom.
Do this on test system.
/etc/rcS.d/S30rootusr.sh (<= SunOS 5.7)
/etc/rcS.d/S30network.sh (>= SunOS 5.8)
example:
ifconfig <interface> ether 8:0:20:83:fe:75
If this does'nt solves your purpose, then please provide
the reason why do you want to change the MAC address,
perhaps one may suggest some good alternate method.
Thanks
Kalpesh
