VaultBook for Mac
Runs natively on Apple Silicon and Intel. Open the HTML file in any Chromium browser and your workspace is ready — no install, no Gatekeeper prompts.
Setup on macOS
From download to your first note in under a minute.
1
Download & unzip
Click a download button above. Safari will auto-extract the zip into your
Downloads folder. If using Chrome or Arc, double-click the
.zip to unzip.
2
Open in a Chromium browser
Open VaultBook.html in Chrome, Edge, Arc, or Brave.
Safari is not supported — the File System Access API requires a Chromium browser.
3
Connect your folder
Click the 📁 button and select the folder you extracted.
VaultBook reads the
license.json from this folder and stores all data locally.
macOS notes
A few things to know when running VaultBook on a Mac.
Recommended browsers
Chrome, Edge, Arc, and Brave all support the File System Access API.
Safari does not — VaultBook will load but cannot connect to a local folder in Safari.
No Gatekeeper issues
VaultBook is a plain HTML file, not a signed app bundle. macOS Gatekeeper
does not block it — just open it in your browser like any other file.
Where to store your workspace
Keep the VaultBook folder anywhere — Desktop, Documents, or an external drive.
For automatic backup, place it inside iCloud Drive, Dropbox, or Google Drive.
Apple Silicon & Intel
VaultBook runs identically on M1/M2/M3/M4 and older Intel Macs.
There is no native binary — performance depends on your browser, not your chip.
