In your Embassy, head to System -> Lan -> click Download Certificate and save it to your Mac.
Locate the certificate and double click it.
In the resulting box, choose “System” from the “Keychain” dropdown menu. Then click “Add.”
Enter your computer password when prompted. It will be imported into your mac’s keychain.
If the keychain console did not open, press “Command + spacebar” and type “Keychain Access”, and hit enter to open it.
Navigate to the “System” tab on the left, find the certificate named “Embassy Local Root CA”, and double click on this certificate. A second window will pop up.
Open the “Trust” dropdown and select “Always Trust” from the dropdown next to “When using this certificate”.
Close this window and enter your password to apply the settings.
The “Embassy Local Root CA” cert will now read “This certificate is marked as trusted for all users” in Keychain Access.
No additional setup is required for most browsers and you will now be able to safely connect to your Embassy over LAN.
For Firefox, you will need to follow these instructions.
