Scope
FortiGate.
Solution
From GUI:
Go to Network -> Interfaces -> Edit Interface and along with the interface name hardware address also be added from version 5.4 onward.
In non-VDOM mode.

In VDOM mode.
conf global

Example.
To see the firewall port2 MAC address:
get hardware nic port2
Name: port2
Version: 1.1.29.0-k-NAPI
FW version: N/A
Bus: 0000:0b:00.0
Hwaddr: 00:75:72:61:5f:02
Permanent Hwaddr:00:75:72:61:5f:02
State: up
Link: up
Mtu: 1500
It is also possible to use fnsysctl utility. This will show the current HW address and it works also for virtual interfaces, like VLAN:
Note that when executing the above command on a member of the HA cluster, the primary unit will display the virtual MAC address of the interface, whereas the subordinate unit will show the MAC address programmed by the Network Interface Card manufacturer for the respective vendor.
