Floodtide does not update Tailscale
Tailscale is not published through Homebrew as an app cask. Here is how to update it yourself, and, rather than leave you to find out after paying, the whole reason Floodtide does not.
Update Tailscale by hand
- Check for updates inside Tailscale. Open Tailscale and look in its own menu, or under Help, for Check for Updates. Vendors who publish no public index usually build the updater into the app instead.
- Or download it from the vendor. Sign in to the vendor's site where the download lives, get the current build, quit Tailscale and replace the installed copy with it. Your settings live outside the app and are kept.
Why Floodtide does not
Floodtide learns what the current version of an app is by reading a source the vendor already maintains. For most apps that is the Homebrew cask catalogue or the app's own Sparkle feed. Tailscale has neither in a form Floodtide can read before the app is installed, usually because the vendor puts the download behind a registration form or an account. There is no index to consult, so there is nothing honest to show you.
Tailscale has to be updated from inside the app or from the vendor's site.
Floodtide also reads the Sparkle feed of any installed app that publishes one, which is a separate path from the Homebrew list. If Tailscale ships a Sparkle feed on your Mac, it will appear in your update list even though it is not on the coverage chart.
What this says about the rest
MacUpdater kept a hand-maintained database of every Mac app, which is why it could claim near total coverage right up until the day it could not maintain it any more. Floodtide reads sources the vendors already keep current, so the coverage list is smaller and it does not go stale. The trade is deliberate: a shorter list you can trust beats a longer one you cannot check.
Questions about Tailscale
Does Floodtide update Tailscale?

Will Floodtide ever cover Tailscale?
If the way Tailscale is published changes so that a verifiable version becomes readable, it appears in the coverage list automatically. The list is rebuilt from the live source, so nothing has to be added by hand.
Does Floodtide hide apps it cannot update?
No. Floodtide shows an app it cannot handle with the reason attached, in the app and here. An updater that quietly omits what it cannot do is one you cannot use to answer the question "is this Mac up to date", which is the only question that matters.
