SimpleTopBar

A native macOS menu bar app: a hamburger menu in the menu bar whose panel collects every other app's menu bar (tray) icons, plus every app running on your Mac, into three sections:

• Menu Bar — a tray of all other apps' menu bar items, discovered through the Accessibility API. Click one to open its real menu. Optionally hide the items from the menu bar so they only live inside this panel (best-effort; see below).
• Apps — regular apps that live in the Dock.
• Background Apps — accessory/agent apps without a Dock icon. This section is a dropdown: it stays collapsed to a single header, and when you expand it only the first few apps are shown. The rest are hidden behind a Show N more row so the list never overflows the panel.

Click any row to activate the app, or right-click for Activate / Hide / Quit.

Accessibility permission

Collecting and opening other apps' menu bar items needs Accessibility permission (System Settings → Privacy & Security → Accessibility). The panel prompts for it; without it the Menu Bar section is empty and everything else still works.

Hiding menu bar items (best-effort)

macOS has no public API to move another app's status item. The Hide items from the menu bar toggle uses the spacer technique: a zero-width status item is created at launch whose length is expanded to push the other icons off-screen so they only live in this panel. It is on by default (the choice is remembered), always undone on quit, and if the app dies macOS removes the spacer automatically.

What it can and cannot hide:

• It hides other third-party apps' icons (cmux, Kapture, WireGuard, input source, Now Playing, …) so only your apps' icons leave the bar.
• It keeps Wi-Fi, Spotlight, Clock, Battery and Control Center. The spacer's boundary is tuned (preferred position 250) to fall just left of Wi-Fi, so the Apple items on the right stay visible. macOS reserves that far-right area: a third-party item can never be placed to the right of it, so those icons cannot be pushed away even in principle. (Bartender and Ice hit the same wall and cover the area with their own overlay bar instead.)
• Newly launched apps are placed to the left of the spacer, so they are hidden automatically.
• Advanced: set defaults write dev.tzgyn.simpletopbar debug.spacerPos -float <n> to move the boundary (larger = keep more icons; > ~400 starts leaking app icons back into the bar).

Install with Homebrew

brew tap TZGyn/tap https://gitea.tzgyn.dev/TZGyn/homebrew-tap.git
brew trust TZGyn/tap
brew install --cask simpletopbar

The tap is hosted on Gitea, so the full URL is required. Homebrew may print an "Unsupported tap" warning — it's harmless.

Upgrade

brew update
brew upgrade --cask simpletopbar

If Gatekeeper still blocks the app after upgrading (it is not notarized yet):

xattr -dr com.apple.quarantine /Applications/SimpleTopBar.app

Build from source

swift build                 # debug build
swift run SimpleTopBar      # run from terminal (app appears in the menu bar)
swift run SimpleTopBar --self-test   # headless check of the dropdown logic
./build-app.sh 0.2.0        # release build + SimpleTopBar.app bundle + icon + codesign
./release.sh 0.2.0          # build-app.sh + dist/SimpleTopBar.zip + sha256

Around the Background dropdown

The background section is collapsed by default. Expanding it reveals AppListModel.backgroundPageSize (5) apps at a time; when more are running a Show N more button reveals the next page. Collapsing resets the page.

Releases

./release.sh <version> builds and zips the app to dist/SimpleTopBar.zip and prints its sha256. Tag v<version>, attach the zip to a release on the Gitea repo, and bump version/sha256 in the cask in TZGyn/homebrew-tap.
