Thunderbolt/Gigabit adapter

[CasperSally]

Can anyone with one of the newer adapters confirm if Apple put the mac address on the packaging or device anywhere via barcode? I suppose it's too ugly to hope for this.

We just ordered a whole bunch and dreading plugging them in one by one to get mac address for JSS.

I got a brand new unopened box in my hand and I only see a UPC code and a JAN code.
Just opened it and:
Nothing on the inside paperwork.
Nothing on the adapter itself.

Nothing that looks like a MAC address.

figures as much, thanks.

Only Enterprises need MAC addresses...why do you think it would be there then? However, this is good to know there will be another step in that process when ours gets here.

[CasperSally]

My fear is one adapter mac address is somehow copied/pasted wrong, or doesn't make it to JSS for whatever reason (we're buying a few hundred), then machines imaged with those adapters will be messed up / replace each other in JSS.

My plan is to enter them in JSS as carefully as possible, and then ask the technicians who do the mass imaging to check after second batch they have as many airs in their inventory as they expect.

Best thing I've found (at least with the USB ones) is to plug them into a MAC, go to System Preferences -> Network -> Advanced -> Hardware.

There you can select it and copy. Go into the JSS, paste it into the removable MAC address field.

Here's what we're seeing on a MacBookPro8,2 from early 2011:

replace the awk match string for whatever the usb adapters present themselves as:

/usr/sbin/networksetup -listallhardwareports | awk -v n=2 '/Hardware Port: Ethernet/ {queue[NR+n]} NR in queue {print $NF}'

[donmontalvo]

@rockpapergoat Thanks Nate, trust that I copy/paste to my cheatsheet.txt file whenever you guys post these nuggets! :D

We are also using a Sharpie to put the MAC Address on the Thunderbolt/Gigabit adapter body...hopefully it won't wipe, but if it does we have an engraver. We only have a handful of adapters though...for those of you with MANY of them, I would let your Apple REP know. I just submitted to RADAR (11769043) and I'm forwarding to our Apple rep.
