Does a iMac mid-2014 have two NIC cards?

I was looking at my system info and noticed in Network > Ethernet one MAC address and then Network > Wifi > another MAC address.
I could only see one card Airport Extreme, I could not find info on this on apple.com specs or with a few lazy searches.
If I do have two NIC cards, How does that effect a loopback ping?

Do 'ifconfig' in a terminal window...loopback is on its own interface.

Is there a way to have two payment cards under one apple id

Is there a way to have two payment cards under one apple id?

You're confusing icloud and itunes store accounts. Individual users should have their own icloud accounts (using their Apple ID) but multiple users can share the same ID for logging into the itunes store account.

I'm not aware of any, not to say that there aren't any issues.
it may have nothing to do with ntpd, there are a lot of things running.
ntpd just happen to make the log entry at the same time as the panic.
I would check to see if there are any updates available for you system.
if this is the first time that this has happened. it may be (pick one):
cosmic rays
sun spots
the trilateral commission
if this happens more frequently and that traces look the same, then
there may be a real problem that needs to be looked into further.

Does the iMac 21.5 have a cd rom

i just purchased an iMac 21.5 and i am not sure if it has a cd rom

If it's the brand new thin profile models, these new iMacs no longer have a built-in CD/DVD Super Drive.
You must purchase a separate optical drive and connect it to your new iMac.
Any external Thunderbolt, FireWire or USB optical drive will work.

Do I need (or do I even have) a NIC card? Modem works, comp not responding

Hi All,
Recently we have been experiencing connection problems with our cable modem and Mac. We've had our cable company out several times and I finally believe they have resolved any problems on their end.
Currently all of the cable modem lights are on (normally indicating we should be able to connect) and we are still not connecting. During a phone call to one of our cable techs he asked me to pull up System Preferences and click on Network. Upon doing this I then,under the "Show" drop down menu chose "Network Status". He and I were both surprized that the only thing that showed up in the dialog box was Internal Modem. There was no "Built in Ethernet" which is how our modem is connected to our Mac. He said that Built in Eternet should be there and that I need to get a new NIC (Network Interface Card) to resolve the problem so that the computer can communicate with the modem. Makes sense to me.
My question is this: Is there such a card for a Mac or was he referring to a PC type of card that performs that function. From my converstion with him he is obviously somewhat conversant with Macs (or had good scripts,prompts to read from) so I left our conversation thinking he knew what he was talking about. Is this a piece of hardware or software? I got the impression from him it was a piece of software that needed to be reinstalled. Lastly,where would I obtain the software/hardware?
Sorry about the long post. Any help will be greatly appreciated.
Cheers,
Vance

Both of the G4 Macs you mentioned have built-in Ethernet on the motherboard. They would not require a PCI card to support this function unless the built-in Ethernet hardware on the motherboard were defective (this does not happen often), or you wanted to run much faster than the speed provided by the built-in Ethernet (not generally needed unless you are using a File Server at your location).
You already have a top-notch Apple brand Ethernet interface. Do not let your ISP talk you into installing a different PCI-slot NIC card unless you are certain the motherboard Ethernet is defective.

Why does my MyBook Studio 1 have two firewire 800 ports?

Hi, I have a WD MyBook Studio edition (version 1) that I use as a backup for my iMac (Early 2008). I'm planning to upgrade my iMac's internal drive to 1 or 2 TBs and I want to know if I can add another MyBook onto the one I currently have via its second firewire port. I'm not sure if that's why there are 2 ports, but that's why you guys are here, right? Thanks in advance and if you know any good internal drives send a link my way ;)!

Hi funman895: Yes indeed the Firewire drives can be daisy-chained. So you can add another MyBook to the second FW port on your drive.
Hope this helps

Does my iMac 10.7 have: USB mass storage protocol must be supported by your OS

This is via IRIS=-for IRIS Anywhere 4 business card scanner and then opened using the Cardiris 4 software for insertion into Mac Address Book?

Lion needs 7 GB of free storage in the hard drive, but you have 4 GB of RAM installed (Lion needs 2 GB of RAM memory). Hard drive and RAM memory are different hardware of the Mac

HT4623 Can I have two sim cards on one iphone

I have a personal iphone 4s and a work iphone4 and i hate having two phones and i would like to merge them is this possible or can people call my personal number and it be re-directed to work phone? Or can an iphone run two sims at once like mail can run two emails at once

hi there,
yes, call forwarding is possible. Be aware though, that with call forwarding additional charges might incur.
no, the iPhone does not support Dual-SIM capability.
Hope this helps,

Leopard server 10.5.6 with two nic card and two hostname

Hi,
Here is what I am intending to do but don't know how:
-setup a Mac server that has 2 built-in nic.
-nic1 is setup as a DHCP, has proper hostname, DNS, etc. and connects to internet and is easy when you configure it as a server while is connected.
-But, my other nic2 is not DHCP and is cut off from outside and is intended for internal research, but given a proper IP and hostname.
If I want to install the server, then without internet connection it is hard to complete the setup and If I do then it assigns the hostname pointing to the nic1 (which i don't want)
How should I go about this? I tried both way, but Mac picks the hostname that is associated with nic1 always.
Any help is appreciated!
Thanks

Can you do what you want? Sure. (If I understand what you're up to.) But it gets a little ugly.
It's easier to use a firewall-router-NAT device here.
Dual-NIC configurations and IP are an interesting case.
A firewall-router-NAT configuration and the resulting IP routing works out of the box. It also avoids the case where users and software are active on the firewall (as is the case with a dual-NIC host system acting as a firewall), and where these activities happen to modify the firewall configuration; this whether by accident, by intention, or through an exploit. Firewalls are best kept locked down.
If you want to learn IP routing and preferred paths and other network-level considerations, then by all means do continue to work with a dual-NIC host system. (This isn't specific to Mac, either. This is simply how IP and IP routing works. There's no concept of automatically returning the packets of a connection out the same controller that the connection arrived on, for instance. And various IP protocols don't use connections.)
As for DNS and particularly with NAT, you'll probably end up with a split configuration. I'd tend to have an external DNS provider translate the public DNS domain and the public address, and have the NAT box (with port forwarding) map that to the appropriate private IP address. Within the private address space, a private DNS domain (a subdomain of a public registered domain, or a separate registered domain) uses the local (private) DNS server to resolve its queries, and that DNS server forwards queries for which it is not authoritative to the organization's public DNS server.
Do use node.foo.example.com and node.example.com (where you own example.com) or use node.example.com and node.example.net (where you hold both domains), with the former being external and the latter being the internal address space. Having the same name resolve to two different IP addresses gets weird, as (for instance) a laptop moving between domains (particularly in the co-presence of that abomination known as NAT) may not end up routing its IP traffic where you expect. Having the convention of a specific internal subdomain or a specific internal domain also makes the "inside versus outside" distinction very clear, too. It's possible to use a completely private domain internally, but (given ICANN is opening up TLDs, and in the absence of an ICANN-reserved internal-only domain) I don't recommend that.
If you want to continue with the original course of action, this IP routing and split DNS is a common question. Dig around in the forums, and dig around specifically for discussions of IP default routing, for split-brain or split-horizon or split-zone DNS, consider acquiring Cricket Liu's DNS book (which is what we all usually go read when we hit a DNS weirdness), and for tools such as the CutEdge Systems DNS Enabler tool.

Is there a way to have two sim cards with one icloud?

I am trying to use an ipad mini and iphone. they both have sim cards with different numbers and I am getting the facetime calls on both devices as well seeing iMessage on both devices. But when i try to send a text out from the ipad it doesn't seem to go. I always get the fail to send message.

So it turns out that I was trying to do something that isn't allowed by Apple. I was assuming, incorrectly it seems, that because the ipad had it's own sim card that I could text anyone. But you can only use the iMessage. The sim card is just for connectivity. So it is all good with my iPad and all is working the way it should.

HT201413 I get error 20 when I try to download updates to installed Apple software I have two users on the IMac. I resolve the problem by clearing all cookies on both users Safari. Why do I need to do this? What is going on?

I get Error 20 when I try to download updates for installed Apple apps on my IMac. I have two users on the IMac, and I resolve the problem by clearing all cookies on both users Safari, opening and closing the App Store for each user, shutting down and restarting the IMac for each user, until finally the download works. There must be an easier way. I also have an Air, where I have no problems whatsoever. Both machines have Doorstop and MacKeeper with the same settings, so I have ruled those programs out as the cause. I believe iot is because I have two users - any ideas?

Please read this whole message and be sure you understand all of it before doing anything. Back up all data before making changes to your settings.
Write down the server addresses.
Click Cancel to close the Advanced sheet. Unlock the preference pane, if necessary, by clicking the lock icon in the lower left corner and entering your password. Open the DNS tab again and change the server addresses to the following:
8.8.8.8
8.8.4.4
That's Google DNS. Click OK, then Apply.
In Safari, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If you’re using another browser, empty the cache. Test. Any difference?
Notes:
1. If you lose Internet access after making the above change to your network settings, delete the Google servers in the Network preference pane, then select the TCP/IP tab and click Renew DHCP Lease. That should restore the original DNS settings; otherwise restore them yourself.
2. I’m not advocating Google or anything else as a DNS provider; the server addresses are offerred merely for testing purposes. There may be privacy and technical issues involved in using that service, which you should investigate personally before you decide whether to keep the settings. Other public DNS services exist.

2013 27" iMac, can you have THREE 27" screens NOT mirrored?

Straightforward question:
Say you have the BRAND NEW 2013 27" iMac
Say you have TWO of the 2013 brand new, thunderbolt 27" external monitors.
YES you can plug in both the monitors, giving you "three displays"
HOWEVER
Can you run this as THREE LOGICAL DISPLAYS.
So, you can move your mouse pointer completely from monitor A to B to C
So what I mean is NOT using mirroring in any combination. Three full logical screens?
Is this actually possible?
Has anyone DONE IT and can supply a PHOTO?
Apple DOES NOT answer this question anywhere.
Pls do not answer unless you know the difference between mirrored and logical screens, thanks!
Yes, it says everywhere on the Apple web site you can connect "two external displays". No big deal.
Can you actually have three LOGICAL displays (move your mouse pointer completely from monitor A to B to C, the content of all three screens is completely different).
This is a straightforward question that I have never seen decisively answered. Thanks for any info.

Contacted Apple support with the same question. This is what I heard back. The iMac supports 2 Thunderbolt displays because it has dedicated graphic cards. It supports only 2 thunderbolt displays. Hope it helps.
