Tiemo,

You may need to use two commands if you need the information from both Macs and PCs.

On the Mac, "networksetup -listallhardwareports” in the shell should give you a report that looks like this:
MLRCTBHUB:~ msiskin$ networksetup -listallhardwareports

Hardware Port: Thunderbolt Ethernet Slot 2
Device: en6
Ethernet Address: 00:10:74:b8:02:fd

Hardware Port: Thunderbolt FireWire
Device: fw0
Ethernet Address: 00:0a:27:02:00:6d:57:03

Hardware Port: Wi-Fi
Device: en0
Ethernet Address: f4:5c:89:9e:70:d7

Hardware Port: Bluetooth PAN
Device: en3
Ethernet Address: 7c:d1:c3:9a:1b:cd

Hardware Port: Thunderbolt 1
Device: en1
Ethernet Address: 6a:00:01:b2:92:70

Hardware Port: Thunderbolt 2
Device: en2
Ethernet Address: 6a:00:01:b2:92:71

Hardware Port: Thunderbolt Bridge
Device: bridge0
Ethernet Address: 00:10:74:b8:02:fd

VLAN Configurations
===================
MLRCTBHUB:~ msiskin$

On PCs, you may be able to use the command “getmac” in a shell which should give you a report that looks like this:

C:\>getmac
Physical Address    Transport Name
=================== ==========================================================
2C-3F-45-02-1B-32   \Device\Tcpip_{7E49B486-120A-4BC2-2114-B345A4D5C5}
10-13-17-BC-12-48   Media disconnected
22-B3-C5-30-76-78   \Device\Tcpip_{213E8D2A-1DBE-4240-8301-BE6F3EACAF9D}
00-05-2A-3C-78-00   \Device\Tcpip_{F01E3FC2-A5A1-6940-D1A1-C7521AEC4296}
2C-23-45-14-23-AD   Media disconnected
C:\>

Now I haven’t tried this on PCs, so your milage may vary.  But the macOS version does work.

Good luck,
Marc

Hi Marc,
I need the MAC addresses from all network adapters. How can you narrow the scope of this request?

Tiemo,

I ran the command directly on my Macos 12.4 laptop and it took about 20 seconds to generate the entire listing.

Is there specific information you are looking to obtain?  You may be able to narrow the scope of the request and generate it faster.

Hello,

I am not sure where to start searching and I am not good under the hood of Macs.

I am retrieving MAC addresses:

put "netstat -I" into myShell

put shell(myShell) into tRes

In former times that has taken "a few" seconds, now it takes around 20 seconds. First I tested, if it was a slowdown of LC 8/9, but in LC 6.7.10 it is almost the same 20 secs. I am not sure, when the decrease actually happened, but if it is not LC then it must be an issue of one of the latest MacOSs.

Has anybody any idea, if I can optimize anything in the performance of this shell request? Could it be any permission issue in the new OS? Anything I could workaround, or do I have to take this shell call as it is?

Thanks for any ideas

Tiemo
