Blank / Installing

Installing Blank

Blank is not code-signed yet, so macOS and Windows block the first launch. Nothing is wrong with the app. Here is the whole path through it, once.

macOS

One .dmg for both Apple Silicon and Intel Macs.

Install it

Open the downloaded .dmg and drag Blank into your Applications folder. Then open it from Applications.

Click Done

macOS says it “could not verify” the app. Click Done, and not Move to Bin, which deletes it.

“Blank” Not Opened
Apple could not verify “Blank” is free of malware…
Done Move to Bin

Allow it once

Open System Settings → Privacy & Security, scroll down to Security, and click Open Anyway.

Security
“Blank” was blocked to protect your Mac. Open Anyway

Start writing

Authenticate, click Open, and choose a folder for your writing. It opens normally from now on.

Right-click → Open no longer works. Apple removed that shortcut in macOS 15 (Sequoia), which is why the dialog offers only Done and Move to Bin. The Privacy & Security route above is the current one.

Windows

Take the .msi installer, or the .exe setup beside it. Either one works.

Run the installer

Double-click the downloaded .msi.

Click More info

SmartScreen says it “protected your PC”. Click More info. The link is easy to miss, and there is no other way forward.

Windows protected your PC
Unrecognised app · Publisher: Unknown
More info Don't run

Run anyway

Click Run anyway, then follow the installer.

Start writing

Launch Blank from the Start menu and choose a folder for your writing.

Linux

No security prompt here, just make it executable.

AppImage

chmod +x Blank_*.AppImage then run it. Works on most distributions with no install.

Debian / Ubuntu

sudo apt install ./Blank_*.deb installs it like any other package.

Questions

Why is it not signed?

Signing requires a paid Apple Developer account, and Windows code signing costs more again. Neither changes the app, only whether your system recognises the publisher. It may be signed later.

Is there a terminal shortcut on macOS?

Yes: xattr -dr com.apple.quarantine /Applications/Blank.app removes the quarantine flag and skips the Privacy & Security step.

Where does my writing go?

Into a folder you choose on first launch, as one plain Markdown file per entry. Pick an iCloud Drive or Dropbox folder and it syncs. You can move it later with “Change writing folder…” in the command palette (⌘K).

Do I have to install anything at all?

No. Blank runs in your browser with the same features. Entries are saved in that browser rather than as files on disk.

How do I uninstall it?

Drag Blank from Applications to the Bin on macOS, or use Add or remove programs on Windows. Your writing folder is untouched. The files are yours.
