A Mac with Apple Silicon running macOS 14 or later, and one or more Google accounts — regular Gmail addresses or Google Workspace, both are fine. Nothing else: Nuncio has no account or sign-up of its own.

By design: all system permission prompts arrive at one predictable moment — right after installation, or on a fresh install right after your first sign-in — instead of scattered throughout your day. Downloads access is for the downloads bar; microphone and camera are used exclusively for video calls in Google Meet and nowhere else.

If you decline something, you can enable it later in System Settings ▸ Privacy & Security.

Click the "+" at the bottom of the account bar (or Account ▸ Add account). You first pick a name and color; then the regular Google sign-in appears. Every account gets its own fully isolated storage — accounts never see each other.

Correct, unfortunately: Apple reserves passkey handling for full browsers, so the embedded web view can’t offer it. In the Google sign-in screen, choose "Try another way" and sign in with your password — it’s a one-time thing; you stay signed in afterwards.

Yes, fully — including Workspace environments with a custom product name. You sign in as usual; your organisation’s admin policies remain in force, because it is the real Gmail web interface.

Sign out only clears the session (cookies and site data) — the account stays in your bar and you can sign in again. Remove takes the account away and erases all of its data from your Mac.

Right-click the account circle ▸ Edit…. Name and color live together there: eight fixed colors as swatches, plus a color well for any color you like (with color wheel, eyedropper and hex input). The color shows up as the ring around the circle, in the floating panel and on notifications.

That only happens if you kept the suggested name ("Account 2"): after the first sign-in, Nuncio fills in your address automatically. A name you chose yourself (say, "Work") always stays.

Yes — drag the circles up or down in the account bar. The order also determines the shortcuts ⌘1 through ⌘9.

Usually desktop notifications are turned off in Gmail itself for that account; Gmail then simply sends nothing. Open Settings ▸ Notifications in Nuncio: each account has a status row — green means it works, orange ("no notification seen yet") almost certainly means it’s off in Gmail. The button next to it takes you straight to the right Gmail settings page: under General ▸ Desktop notifications choose "New mail notifications on" and click "Save changes" at the bottom.

Also check once that macOS allows Nuncio to send notifications (System Settings ▸ Notifications ▸ Nuncio); Nuncio warns you in Settings if that was declined.

Were you looking at the account that received it? Gmail deliberately doesn’t notify for the account that is visible — you can see the mail arriving. Test with a mail to an account you are not looking at, or use Test ▸ Send test notification in the menu bar.

Yes: right-click the account circle ▸ Edit… ▸ "Notifications for this account". Below it you can also turn off only the slide notifications for that account and keep the regular banners. The main switch is in Settings ▸ Notifications.

Yes: Calendar reminders arrive as regular Nuncio notifications; clicking opens that account’s calendar. Two requirements: turn on desktop notifications in Calendar itself (⚙ ▸ Settings ▸ General ▸ Notification settings), and keep Calendar open as a tab for that account — saved tabs load automatically in the background after launch.

Nuncio comes to the front, switches to the right account and the right app, and where possible opens the exact message or event.

A small dark panel that floats above all your other apps, in every Space: your accounts with their unread counts, always visible. Click an account and Nuncio jumps to it. When mail arrives, a clickable card slides out of the panel, next to that account’s circle.

All three. Drag it (grab the dark background) wherever you like — the position is remembered, even across restarts. In Settings ▸ Floating panel you pick the orientation (vertical or horizontal) and can turn the panel or just its slide notifications off. Per account, Edit… decides whether it appears in the panel.

macOS shields Focus status from apps; to read it, Nuncio needs Full Disk Access (System Settings ▸ Privacy & Security — Settings ▸ Floating panel has a shortcut). With that access, Nuncio suppresses slides during any Focus mode; the regular notification banners respect Do Not Disturb regardless, because macOS filters those itself.

At every level. Settings ▸ Badges has the main switch "Show unread counts" (circles, floating panel, window title and Dock in one go) and a separate switch for the Dock total. Per account: Edit… ▸ "Show unread count" — that account then also stops counting toward the Dock total.

The badge counts what your open Gmail tab reports (usually Primary). Gmail’s total across all categories — Promotions, Social — is often much higher. This keeps the badge a measure of what you actually want to see.

That account is signed out (the session expired or was cleared). Click it and sign in again; the badge and notifications return by themselves.

By design: pop-out compose windows and pop-out messages become tabs in the top bar, so everything stays visible in one window. Sending closes the tab by itself; the close button (appears on hover) or ⌘W closes it manually. Only sign-in pop-ups open as separate windows — a login flow would break inside a tab.

By design: if Nuncio quit, your notifications and badges would stop too. Closing the window only hides it; click the Dock icon (or a notification) to bring it back. ⌘Q really quits.

⌘1–⌘9 pick an account · ⌘⇧[ and ⌘⇧] previous/next account · ⌘⌥← and ⌘⌥→ previous/next app · ⌃⌘S show/hide the account bar · ⌘N new mail (as a tab) · ⌘W close tab or app · ⌘R reload · ⌘+ / ⌘− / ⌘0 zoom · ⌘, settings.

Yes: empty bar space behaves like a title bar (dragging moves the window, double-click zooms). Tabs and buttons keep their own behaviour and never drag the window by accident.

Yes, by design: external links open in your default browser, so Nuncio stays a mail client rather than becoming a browser. Google links are the exception — a Drive link in Gmail opens your own Drive tab for that same account. If you’d rather keep external links inside Nuncio, turn off Settings ▸ General ▸ "Open external links in the system browser".

In the bar that appears at the bottom whenever something downloads: progress per file, click to open, right-click for Show in Finder. The files themselves are simply in your Downloads folder.

Check the bar at the bottom of the window — small files often finish before you notice. If the bar stays empty, check that Nuncio has access to your Downloads folder (System Settings ▸ Privacy & Security ▸ Files and Folders).

Nuncio asks once by itself. After that it’s always available in Settings ▸ Default mail — macOS asks for confirmation. Manually works too: Apple Mail ▸ Settings ▸ General ▸ Default email reader ▸ Nuncio.

With multiple accounts there is deliberately no fixed default mailbox: on every mailto link you choose again via "Choose mailbox" — your accounts with photo and address. With one account the message opens directly. Address, cc, subject and body are pre-filled; the message opens as a tab. Close the chooser without picking (✕, Esc or clicking beside it) and nothing happens.

Six: English, Dutch, French, German, Spanish and Italian. The app follows your Mac's language order automatically. Want Nuncio in a different language than the rest of your Mac? System Settings ▸ General ▸ Language & Region ▸ Applications ▸ + ▸ Nuncio, and pick the language there. If your Mac speaks a language Nuncio doesn't know, it falls back to Dutch. Note that the Gmail panes themselves follow your Google account's language setting, not Nuncio's — you change that inside Gmail.

Yes. By default everything follows your Mac’s system theme. In Settings ▸ General you choose System, Light or Dark — and with Light or Dark the web apps recolor along by default, via smart inversion that keeps photos in their real colors. A web app that is already dark (like Gmail with its own dark theme) is left alone. The recoloring can be switched off separately.

That’s Google’s one-time chooser per account. Nuncio answers it automatically with "Device default" — the option that follows Nuncio’s theme. If you do see the dialog, pick "Device default" yourself; the effect is the same.

Yes. Gmail stays loaded for every account, so switching is always instant — even with six accounts. Only the active page is rendered; the rest is parked without drawing anything.

Settings ▸ General ▸ Memory. Efficient (recommended) unloads only the other tabs (Calendar, Drive, …) you haven’t used for fifteen minutes; they reload in a few seconds on the next click. Everything warm unloads nothing. Gmail stays loaded in both modes.

No. Nuncio is native Swift with your system’s WebKit (no bundled Chromium), does no background work in the interface, slows itself down automatically in Low Power Mode and pauses completely as soon as your screen sleeps.

Everything stays on your own Mac: each account lives in its own isolated storage (cookies, sign-ins, site data), like separate browser profiles. Nuncio has no servers, no accounts and no telemetry — nothing about your use is collected or sent anywhere. The full privacy policy spells this out.

That account’s entire storage (sign-in, cookies, site data, avatar) is erased from your Mac. Your Google account itself is of course untouched — only the local access disappears.
