Link to Matriarch 1.3 Firmware points to 1.2.3 (MacOS)

So, I’m sure this is somehow user error, forgive me. But when I attempt to download this from here, the link points to
here. The Moog Firmware Updater (Mac) file, when unzipped, only contains files pertaining to 1.2.3. Is this release Windows-only, or am I missing something?

Thanks y’all.
