Which MAC address do you need? There are multiple MAC addresses. If you want the MAC address of the fuse, just use this example

uint32_t chipId = 0;

void setup() {
Serial.begin(115200);
}

void loop() {
for (int i = 0; i < 17; i = i + 8) {
chipId |= ((ESP.getEfuseMac() >> (40 - i)) & 0xff) << i;
}

Serial.printf("ESP32 Chip model = %s Rev %d\n", ESP.getChipModel(), ESP.getChipRevision());
Serial.printf("This chip has %d cores\n", ESP.getChipCores());
Serial.print("Chip ID: ");
Serial.println(chipId);

delay(3000);
}
