No Mac users listed today (though past records are still displaying as before). For today, I’m seeing 552 PS5 users, 4 Xbox, and 12 “other”.
Thanks for confirming, checked with the mod.io team and it does seem to be a visual bug they're looking into at the moment! The numbers come from cross-play sessions where the PC host has this mod installed and console players are notified that there is a discrepancy in the shared mods in the session.
