2017 macos sierra mail mac address offline

A specific question!

To find the Mac address of your Mac running macOS Sierra (10.12) in the Mail app when you're offline, you can follow these steps:

1. Open the Mail app on your Mac.
2. Click on the "Mail" menu at the top of the screen and select "Preferences".
3. In the Preferences window, click on the "Accounts" tab.
4. Select your email account from the list of accounts on the left side of the window.
5. Click on the "Advanced" tab.
6. Scroll down to the "SMTP" section.
7. Look for the "Server" field, which should display the Mac address of your Mac.

Alternatively, you can also use the ifconfig command in the Terminal app to find the Mac address of your Mac:

1. Open the Terminal app on your Mac.
2. Type the following command and press Enter: ifconfig en0 | grep "ether"
3. This will display the Mac address of your Mac, which should be in the format xx:xx:xx:xx:xx:xx.

Note: en0 is the default Ethernet interface on most Macs, but if you have multiple network interfaces, you may need to use a different interface name (e.g., en1, en2, etc.).
