Update Gadget II on a mac

Hello everyone!

Is it possible to upgrade the Gadget II firmware using a mac? Contrary to the console or PC version, there's no firmware box on the maintenace eos settings menu. And I can´t find a way to do it using Concert...

Do I need to do this exclusively on a PC/nomad or console (or Updaterator)?

Thanks in advance,

Filipe
