Works on Macs without a notch

OmniMac derives the island from the screen, not from the model: it reads the safe area, and when there isn't one it draws a floating island sized to the display. So it works on an iMac, on a Mac mini with an external monitor, and on a 2019 MacBook — not just on a 2021+ MacBook Pro.

To be straight about it: OmniMac isn't the only one that does this. Notchy does it too, and it's free — though closed source. Atoll is open source but needs a notched MacBook. What's unusual here is having the island and ten other utilities in the same 16 MB process, under MIT, with the idle cost measured and published.

What it replaces

Instead of	You get	Costs
Amphetamine	Keep awake, closed-lid mode, triggers	Free
Rectangle	Window shortcuts, drag-to-snap, saved layouts	Rectangle Pro is paid
Maccy	Clipboard history with images, files and pins	Free
AltTab	⌘Tab by windows, with live thumbnails	Free
SoundSource	Per-app volume + 10-band equaliser	$47
TextSniper	Copy text from the screen (OCR)	$7

It doesn't replace everything Ice does (its menu-bar hider is much simpler) or Stats (that one reads fans and far more sensors). Both are excellent — go install them if that's what you need.

Everything it does

Module	What it does
▮ Dynamic notch	Hover and it expands: music, a file tray with AirDrop, today's calendar, sound, timer and Pomodoro, performance. Sneak peek on track change, an iPhone-style card when AirPods connect, the charger's watts when you plug it in. Works without a notch.
☕ Keep awake	Indefinitely, on a timer, or until a given time. Stays awake with the lid closed, stops on low battery, turns on with the charger or an external display.
⌘ ⌘Tab by windows	All your windows, not just apps, with live thumbnails. Type to search; ⌘W / ⌘M / ⌘H / ⌘Q act on the highlighted one.
▭ Window shortcuts	Halves, thirds, quarters, almost-maximize, next display. Drag to an edge to snap. Layouts saved on ⌃⌥1…9, like radio presets.
📋 Clipboard	Text, images and files. Search, pins, pause, optional persistence. It never records what you copy in a password manager, or in any app you add to the list. ⌥⇧⌘V pastes without formatting, and it can strip tracking from links as you copy them.
🔊 Sound	Per-app volume, a 10-band equaliser (global or per app) with nine presets, boost past 100 % with a limiter, output priority, and a standalone mixer on ⌃⌥⌘V.
📈 Performance	Per-core CPU (efficiency vs performance), GPU, memory with pressure, disk, network, temperature, and which apps are eating your Mac. Alerts when something goes wrong. Battery health: capacity against new, cycles, charger watts and a day-by-day history, plus alerts to unplug at the level you pick (even below the 80% where macOS's own limit stops) or when it runs hot while charging.
🛠 Tools	Screenshots to the clipboard: an area (⇧⌘7) or a scrolling capture (⇧⌘8): scroll through a whole page or chat at your own pace and it comes out as one image. OCR (⇧⌘2), colour picker (⇧⌘6), mic mute, keyboard lock for cleaning, hide desktop icons, hold-to-quit guard, and dimming below macOS's minimum brightness.
⌘ Command bar	⌥Space and type: every OmniMac feature and every app. Off by default — ⌥Space belongs to Raycast for a lot of people.
🫥 Menu bar

Every module can be switched off, and a switched-off module frees its resources and disappears from the menu.

Why it's light

0.017–0.033 % CPU and 86 MB at idle (33–37 MB of real memory), measured with a published, reproducible method — the scripts are in the repo.

The rule the whole app is built on: do work only when something needs it. The performance charts only sample while you're looking at them. The notch stops all work when it folds. The audio engine isn't even created unless you've set something to apply; when it is (an app with its own volume, or the equaliser on), it works while that app is open, at about 0.3 % CPU.

Some things do run in the background: the clipboard history checks the clipboard once a second (four times a second for four seconds after you copy something), the performance alerts take one cheap sample a minute (with the charger plugged in, every other one also reads the battery temperature), and, only if you turn it on, the Downloads installer looks at your Downloads folder every 8 seconds. The clipboard module and the alert rules can be switched off in Settings.

	OmniMac	Amphetamine	AltTab	Rectangle	Maccy	BoringNotch	Ice	FineTune
CPU at idle	0.017–0.033 %	0.000 %	0.020 %	0.040 %	0.020 %	0.340 %	0.040 %	0.000 %
Memory (RSS)	86 MB	100 MB	212 MB	84 MB	91 MB	149 MB	99 MB	116 MB

Those seven together take 851 MB. OmniMac does their job with 86 MB. Full method and caveats →

Install

brew install --cask BySergiMM/tap/omnimac

Or download OmniMac.pkg and open it. The installer only copies the app to /Applications and opens it; it installs no administrator rule (see closed-lid mode below).

First launch: OmniMac isn't signed with a paid Apple developer account, so macOS will refuse to open it. Go to System Settings › Privacy & Security and click Open Anyway. Sorry — that's $99/year I haven't spent yet.

Requirements: macOS 14.2 (Sonoma) or later, Apple silicon or Intel.

Permissions

Each one is asked for only when a feature needs it. The one you can meet at launch is Accessibility: OmniMac asks for it when it starts with ⌘Tab by windows or window snapping switched on, because both need it.

Permission	What needs it
Accessibility	Window management, ⌘Tab, paste from the clipboard
Screen Recording	⌘Tab thumbnails, OCR, colour picker
Calendar	Only the notch's calendar tab
Audio capture	Only per-app volume and the equaliser
Administrator password	Only closed-lid mode, and only if you turn it on (below)

Closed-lid mode (Keep awake › "Stay awake with the lid closed") is off by default. It uses pmset -a disablesleep, the setting that keeps a Mac awake when you close the lid, and macOS only lets an administrator change it. When you turn the mode on, OmniMac first shows what it is about to do and asks you. If you continue, macOS asks for your password once and OmniMac installs /etc/sudoers.d/omnimac-lid (checked with visudo before it goes in place): a sudoers rule that lets your user run exactly pmset -a disablesleep 1 and pmset -a disablesleep 0 without a password, and nothing else. While the rule exists, any program running as your user can change that one setting without asking. OmniMac turns the setting back off when the session ends, when you quit and when it launches.

Turning the mode off doesn't remove the rule, and neither does dragging the app to the Trash. To remove it: sudo rm /etc/sudoers.d/omnimac-lid, or run scripts/uninstall.sh.

No accounts, no analytics, no servers of its own. OmniMac makes two kinds of network request, and nothing else:

• The update check against GitHub, once a day. You can turn it off in Settings.
• Spotify cover art. While Spotify is playing, the notch downloads the cover image from the address Spotify reports for the current track.

Known limitations

• Built as a universal binary, but only tested on Apple silicon.
• Not notarized: macOS will warn on first launch (see above).
• The notch reads Spotify and Music via AppleScript, so it doesn't pick up "now playing" from other apps.
• Clipboard history lives in memory unless you turn on "save to disk" (unencrypted); pinned items are always saved to disk, which is the point of pinning.
• macOS won't let any app remove ~/Library/Containers folders, so the cleaner marks those "Finder only" instead of failing silently.
