What's inside
Clipboard history
Your last copies, newest first, with image thumbnails. Pin the keepers, search instantly, and paste straight into the app you were using.
Sticky notes
Drop color-coded sticky notes on your desktop. They survive reboots and can be spun up from any clipboard item.
Markdown reader
Open any .md file in a clean offline reader — code highlighting, tables, and Mermaid diagrams. No network, no tracking.
Stays out of the way
A pure menu-bar app — no Dock icon, no clutter. It's only there when you summon it.
Yours, locally
No accounts, no telemetry, no cloud. Clipboard and notes live in ~/Library/Application Support/PowerBoard/.
Installing Power Board
Power Board is self-signed, not notarized by Apple — so Gatekeeper will challenge the first launch. It's a one-time, 30-second dance. Totally safe.

Let it past Gatekeeper
Double-clicking the first time shows a “can't be opened” notice. Pick one of these:
Easy way — right-click
- Right-click (or ⌃-click) PowerBoard.app → Open.
- Confirm Open in the dialog. You won't be asked again.
Instead of OK, right-click the app → Open, then confirm.
Terminal way
Strip the quarantine flag, then it opens normally:
xattr -dr com.apple.quarantine /Applications/PowerBoard.app -

Grant Accessibility
The double-tap ⌃ hotkey and paste-on-pick need Accessibility. On first launch Power Board asks once; or add it manually:
- Open System Settings → Privacy & Security → Accessibility.
- Toggle Power Board on.
Done — double-tap ⌃ Control anywhere and the panel appears.
FAQ
Why does macOS say it “can't be opened”?
Because the app is self-signed rather than notarized by Apple. It's safe — run step 3 above (right-click → Open) once and macOS remembers it.
Apple Silicon only?
The current build is arm64 (M1/M2/M3/M4). If you're on an Intel Mac, reach out and I'll ship an x86_64 build.
Which macOS versions?
macOS 14.0 (Sonoma) or newer.
Is my data sent anywhere?
No. There is no network code in the app. Everything stays in ~/Library/Application Support/PowerBoard/.
How do I uninstall?
Quit the app, drag PowerBoard.app to Trash, and optionally delete ~/Library/Application Support/PowerBoard/.
