This could be a “nasty” for remote updating. Thank you for the public service announcement on this.
I have been seeing this more and more as well, but not really after CDVR updates, but whenever apple does point updates to Sequoia - thats when I see em.
Like last week for when I updated from MACOS 15.5 to 15.6 I saw these popups related to channels. There have been two point updates recently 15.6.1 and 15.6.2. I dont use auto updates on my mac, so I haven’t seen the popups yet after updating MACOS again but I just confirmed updating channels to latest prerelease DIDNT cause the pop ups this morning.
When I remote update channels I’m already using Tailscale, so I guess in a weird situation with pop ups happening when I’m not at home I would Remote Desktop into my machine, or I’d figure out a way through SSH to grant permissions if possible.
Good to keep aware of this, especially if the trend continues with MACOS26 and undoubtedly many point updates in the fall!
