maralcbr proposed omacom/omarchy#16986, which 
emirb merged into the quattro development branch. It adds the Apple Silicon templates needed to select RC, while keeping edge as the default and stable unavailable. Package-repository master commits also add checks that refuse promotions of an unqualified Mac package set and check every planned slot before publishing: omacom/omarchy-pkgs@05422a2243fb and omacom/omarchy-pkgs@1359fc98322b.
After the merge, 
ryan-winkler requested a documented upgrade path, the first published build containing the templates, and separate migration guidance for users of the older Mac fork in omacom/omarchy#16986:issuecomment-6495243961. Their installed system still lacked the templates despite seeing RC packages, and they explicitly had not tested a live channel switch. The development merge therefore establishes channel support without establishing that every existing Mac installation can already reach it.
