I think the best argument is to remind Apple that they aren't selling the OS anymore, so they don't need a new version every year. And that macOS features is not what is pushing Mac sales. People aren't buying the M series machines because of the new macOS version, they are buying it because of the hardware. The M series chips are impressive and provide some great benefits that you can't get elsewhere. And that hardware needs to be coupled with solid software to hook and keep people on this computer. So they can take more time to create more compelling upgrades and sand off more edges. I think they need to desync all their OS's and focus on providing better releases. There really is no benefit to spending the day updating your Mac, phone, tablet, appletv, and HomePod. Especially when there are no good reasons to update. I feel like Apple became far to addicting to habit and routine that it's become more important to keep that than deliver product. Apple Intelligence is a good example of that.
