When Apple first introduced the notch to the MacBook Pro, the community was split. Some people didn't mind it, while others found it visually distracting. This divide led to the creation of two very different types of apps: those that try to hide the notch, and those that try to make it useful.
TopNotch is the king of hiding it. OneNotch is the king of using it. Here is how to decide which approach is right for you.
TopNotch: The Eraser
TopNotch has one single, simple job: it makes your macOS menu bar completely black.
Because MacBooks use MiniLED displays, rendering a pitch-black menu bar effectively blends the physical notch into the screen, making it practically invisible. It's a fantastic, free cosmetic utility that does exactly what it promises.
If looking at the camera cutout actively bothers you, and you want your screen to look like a perfect rectangle again, TopNotch is the app for you.
OneNotch: The Utility Belt
OneNotch takes the opposite approach. If the notch has to be there, why not give it a job?
Instead of hiding the cutout, OneNotch wraps a powerful, interactive dashboard around it. It turns dead space into the most productive part of your screen.
Here is why you might want to embrace the notch instead of hiding it:
1. Incredibly Low Resource Usage
The obvious fear: TopNotch is a static black bar that costs nothing, so surely a whole dashboard — clipboard manager, AI-agent monitoring, media controls — will cost your battery?
We had the same worry, so we measured it properly with Apple's own profiling tools instead of guessing. On a Release build:
- ~0% CPU sitting idle in the notch
- under 1% CPU while music plays with the default waveform
- 95–130MB memory, flat even after 8+ hours
In other words, the day-to-day battery cost of running the full OneNotch dashboard is close to the cost of running a cosmetic black bar. You are not trading battery life for functionality. The full measurement write-up is here, numbers we were not proud of included.
2. The Ultimate Clipboard Manager
Why travel to the corner of your screen to paste something? OneNotch stores your clipboard history right on the notch.
- Use Copy Stack to copy multiple items and paste them in sequential order.
- Organize text into Boards for easy access.
- Access a floating panel right at your cursor with a keyboard shortcut.
3. AI Agent Monitoring
For developers and power users, OneNotch is the only app that integrates with AI coding agents like Codex and Claude. You can monitor API responses, task progress, and token quotas directly on the notch. It frees up your terminal windows and keeps you in the zone.
4. Media & Live Activities
OneNotch also handles Now Playing media controls, calendar previews, and iOS-style Live Activities, giving you all the benefits of a "Dynamic Island" without the bloat.
Which should you choose?
- Choose TopNotch if: You want a purely aesthetic fix. You don't need extra productivity tools; you just want the camera cutout to disappear, and you want it for free.
- Choose OneNotch if: You want to work faster. For a one-time $9.99 lifetime purchase—currently $6.99 with launch code
LAUNCH30—OneNotch turns an annoyance into a feature: a clipboard manager, an AI-agent monitor, and media controls in one, at a measured ~0% CPU when you are not using it. You keep the all-day battery and gain the workflow.
