Does the ethernet adapter have a MAC address?

Hi, I wonder if anyone can answer this one for me. I use programs under bootcamp that need a 'dongle' to prevent them being used on more than one machine at once. ProE for example uses a Pluscom ethernet adaptor that carries its own unique MAC address that the license is assigned to. My question is, is the Mac ethernet adapter the same? does it have a unique address - should be six pairs of numbers / letters.
Just wondering if I could use one of the Mac adapters for this purpose.
Thanks for any help

Yes, the Apple Ethernet adapter will have a Media Access Control (MAC) address. In general, every network adapter (NIC) will have a unique MAC address. So if your program only works with a specifc MAC address, basically you can't install the program on a different computer without contacting the software vendor for a new installation code or whatever. (More specifically, you can't change the NIC. If you change computers, you need to keep the NIC.)
In Windows, to get the MAC address, open a command prompt and type "IPCONFIG /ALL" (without the quotes.) The line that says "Physical Address" is the MAC address. Note that you may have more than one NIC. (Wired, Wi-Fi, etc.) So you need to be sure you get the appropriate MAC address for the desired NIC.

Does the C7200 All in One have a MAC Address?

I need the MAC accress from the printer so I can enter it into the security of my router. Does the printer have a MAC address and where do I find it?

As a side note -- MAC-filtering does not improve the security of your wireless-network in any meaningful way. The best way to secure your home wireless network is to use WPA-PSK (or WPA2-PSK) encryption.
MAC-filtering is easily spoofed. It's trivial to listen in on a wireless network, note the MAC addresses being used and to reprogram one of those MAC addresses into your notebook's wireless radio.
BTW -- hiding your SSID is also a bad idea from a security point of view since it doesn't hide your network at all.
There's a good discussion here on this subject.

I have two .mac addresses; how does this work in iCloud?

This is not about consolidating Apple ID's... I think.
When I got my first .mac address, I thought I picked a good one at the time. Later on, due to the peculiar spelling, I opted for an additonal (paid) address which I use every day. Now the first one (which is an Apple ID) contains my calendars, contacts, etc. I never use the email portion of it, again because of challenging spelling. The second .mac address (also an Apple ID) is an email only account. This is the email account I use daily.
When I make the transition to iCloud, I intend to keep my original AppleID (from the pre-.mac days) as my iTunes store ID.
My question is, what happens with my two other accounts?
.mac #1 with the contacts and such would move to iCloud and sync everything there as it currently does with MobileMe. Since .mac #2 is an email only account, would I even need to bother moving it to iCloud (if that's even possible), or would I just keep using that as email only using the current mail settings on my iThingys and Mac? Does anyone know if .mac #2 will live on after MobileMe vanishes, or will I loose my daily and coveted .mac email at that time?
I'm sure Apple has a good reason for not allowing us to just consolidate everything in one place, but I know there are many out there with a similar situation to mine.
I've spent a good deal of time tonight searching the various threads and can't seem to find an answer to the two .mac email dilemma. My appologies if it's already been discussed.
To sum up, I have one Apple ID that I use for iTunes and intend to keep as such. I have two .mac addresses which are also Apple ID's; one that syncs with MobileMe and one that is email only. I would like to use iCloud to sync what is currently on MobileMe, AND continue to use the simpler email address that I've been using for years.
Am I screwed??
Thanks in advance for your help, and Happy Holidays to all!!

Migrate the account which contains your calendars, contacts etc. first, at http://me.com/move and set it up on your Mac and devices.
http://www.apple.com/icloud/setup/mac.html
Now migrate the email-only account in the same way. On a Mac you can add it in System Preferences>Mail, Contacts & Calendars - it won't sync anything but will be added to the accounts in Mail where you can then use the email in the normal way.
I don't know what the equivalent process on an iOS device is; very likely you need to add it as an account in the Mail app.

Does the Base Station HAVE to be connected to a computer?

Due to some new wiring in my house, the room where my computer now is is a few rooms away from a phone outlet. I have an Apple Extreme Base Station, and this is my previous my wireless set-up:
DSL phone line goes into router/modem, which is then plugged into the Airport Extreme Base Station. The Base Station is then plugged into the Ethernet port of my G4 (which also has a wireless card).
My question is whether my computer has to be plugged into the Base Station at all, considering that it already has a wireless card? Since the Base Station is already configured, can my computer just get DSL access across the wireless net from a few rooms away via it's wireless card? Or does the Base Station have to be hardwired to a computer in order to properly operate?
Thanks in advance.

Nope, hard wiring your computer(s) to the ABS isn't required. In my case, I run a PowerMac, Mac mini and two laptops off one ABS with a cable modem input (range extended with three AirPort Express modules). None of the computers are hardwired to the ABS...all connect wirelessly.

Does the ethernet port work when the using airport express in client mode?

I am considering using an airport express to extend my existing wireless network to a room where I can't get a cable to.
I will need to connect a at least 3 devices to the airport express.
The questions are:
- is an airport express the right answer to this problem?
- if so, does the ethernet port work (AE on client mode) as a passthru into the main network?
- can I plug a hub to it?
Thanks
RFSF

Hi Tesserax,
Really appreciate you taking time to respond.
I stopped by the Apple store this weekend and one of their sales people ( not one of their genius bar people) told me NO to all questions. I tend to believe more answers from people in this forum but just realize that I have not mentioned one possibly important point:
the main AP to which I will be connecting the airport express is not an Airport Extreme/Express AP.
Thanks,
Ricardo.

Does the Flashback malware have an effect on OS X systems without java installed?

Does the Flashback malware have an effect on OS X systems without java installed? Just asking since i do not have java installed...

It's not likely, but better safe than sorry. See
Helpful Links Regarding Flashback Trojan
Visit Thomas Reed's site for insight and help: Mac Malware Guide
A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started. However, be careful about what you do as new variants of the malware circumvent the efforts of earlier tools.
Also see Apple's article About Flashback malware.
Apple has released Java updates for Snow Leopard and Lion users:
Java for OS X Lion 2012-003; available only for users of Lion with Java installed.
Java for Mac OS X 10.6 Update 8; available only for users of Snow Leopard.
Flashback malware removal tool; available only for users of Lion without Java installed.
Install whichever shows up in Software Update. It removes the malware (if present), updates Java (if present) and tightens up Java settings for the future. You may download from Apple's web site instead of using Software Update, but it's important to know which one to get, because the other two won't work for you.

Does the Macbook Pro have a program to run Windows built in? If not, what is the best program to do so. Purchasing a new Mac.

No. The Mac does not have anything to run Windows
You must install either virtualizrion software or use BootCamp to create a partition for Windows. Once you have done that then you must install Windows.

iMac G5 - you are at the end of the line, though you may be able to upgrade your RAM, or hard drive.
iMac CoreSolo, CoreDuo - you can upgrade to 1 GB of RAM or 2 GB of RAM and get up to 10.6.8.
iMac Core2Duo - you can upgrade to 2 GB of RAM or more and get up to 10.7.2.
Go to Apple menu -> About This Mac to determine which Mac model you have.
Here's what you have to watch out for on 10.6 to 10.6.8.
Here's what you need to watch out for on 10.7 to 10.7.2.
Some stores may not have 10.6 installer CD available, or may not have 10.7 Flash drive available. For those you have to make the purchase from elsewhere,
and bring it in to the store with you. http://www.apple.com/retail has phone numbers for all their stores, and extension 5 often will get you a real person at the store, though if yuo don't get it, you might try a different extension.

Unfortunately I lost my life and am trying to rebuild. Isn't the technical era great.
Backup, backup, backup
As a minimum, use 3-2-1 (or even more)
3 copies of your data (original copy counts as 1)
2 different backup utilities/storage formats (protects from bugs in the software)
1 copy off-site (protects against theft, fire, and natural disaster)
More backup copies are even better.
Backup disks are cheap compared to the lost of personal data that does not exist anywhere else.

Is the Gmail sync option in Mac Address Book bidirectional ?

Is the Gmail sync option in Mac Address Book bidirectional ?
basically, If I put information directly online on Gmail Address Book will the information go on my computer's Address Book ?
can anyone explain with his/her experience ?

SangomaDB wrote:
It is bidirectional, but I'm not sure how often the sync is triggered, or what triggers it. I saw some stuff on the web that talks about setting it up with Google Sync, but I have not really tried it.
*_Question on: Is it Bidirectional ?_*
How can you confirm it is bidirectional ? I have not seen a site that confirms that is it bidirectional.
*_Question on: How often the sync is triggered ?_*
ONLY when Google Sync is activated from Address Book, you will see a file created in ~/Library/LaunchAgents/com.google.GoogleContactSyncAgent.plist which contains the sync schedule, which by default is 3600seconds (an hour).
The user can change the sync schedule by editing that file using TextEdit.
*_Duplicates using Google sync with Address Book_* ?
I've noticed that my 2000 contacts where duplicated at least 3 times which then I had 5800 contacts about.
Is there any way to stop that ?

Will I Still Have a .Mac Address

I have not switch to iCloud yet, mainly because I currently do not wish to upgrade my Mac to Lion as I would lose the functionality of some software I use just about daily. But next year when MobileMe is sent packing, I will have to switch. When this day comes, will I still have my .mac address? I've used this for so many years, I don't want to have to let everyone know that I have a new address. Also in the Mac mail program I use an AOL account as well, will this address be supported in iCloud as well?

Yes, I believe your .mac email account will still be available once mobileme is fully retired.
You should also have no problem accessing your AOL account through the OS X mail client.
