Notice the MAC address associated with VRID1 in VRRP overview. The first five octets of the address are the standard MAC prefix for VRRP packets, as described in RFC 2338. The last octet is the VRID. The VRID number becomes the final octet in the virtual MAC address associated with the virtual router. Virtual Router is not available for Mac but there is one alternative that runs on macOS with similar functionality.

difference between Virtual MAC Address and Physical MAC Address | Virtual MAC Address vs Physical MAC Address
This page compares Virtual MAC Address Vs Physical MAC Address anddescribes difference between Virtual MAC Address and Physical MAC Address.
Virtual MAC Address
• The virtual MAC address is associated with virtual router.
• It is IEEE 802 MAC Address which is 48 bits in size.
• It has been specified in RFC3768 and RFC5768.
• The hex format for virtual MAC address is as follows:
00-00-5E-00-01-{VRID}
• Here first 3 octets are derived from IANA OUI.
• The next 2 octets i.e. 00 followed by 01 indicate address block assigned to VRRP protocol.
• {VRID} field is VRRP Virtual Router Identifier. Due to 8 bit field VRID, upto 255 VRRP routers are supportedin a network.
It is associated with VRRP virtual router and ARP protocol converts IPv4 or IPv6 into virtual MAC address.The master router uses virtual MAC address as source address in all VRRP periodic messages.
Refer VRRF protocol for more information.
Physical MAC Address
It is also 48 bits in size. It has following 6 hex digits.
Example - 00-14-2A-3F-47-D0
First 3 digits i.e. 00-14-2A represents manufacturer while
last 3 digits represents card or device specific unique number.
