Install Vyapzio on a Mac, step by step

#Before you start

• macOS 12 Monterey or newer. Click the Apple menu → About This Mac to check. The download is universal: it runs on Apple silicon and Intel Macs.
• A licence key of the form VYPZ-XXXX-XXXX-XXXX-XXXX, from your purchase email or your dashboard.
• Internet for the download and the first activation. After that the app works offline for up to 30 days between checks.
• About 400 MB of free space.

#Step 1: Download the disk image

1. Open the download pageOpen the download page and click Download for macOS. The file is called Vyapzio-version.dmg.
2. Open itClick the download in Safari, or open Finder → Downloads and double-click the file. A window opens with the Vyapzio icon and an Applications folder.

#Step 2: Allow the app once

Vyapzio is not signed with a paid Apple certificate, so macOS asks you to confirm it the first time. This is needed once.

1. Right-click Vyapzio, then OpenIn the disk-image window, hold Control and click the Vyapzio icon (or right-click; on a trackpad click with two fingers). Choose Open.
2. ConfirmThe box says macOS cannot check the developer. Click Open again.
3. On macOS 15 or newer, if there is no Open buttonClick Done. Open the Apple menu → System Settings → Privacy & Security, scroll to the message about Vyapzio, click Open Anyway, type your Mac password, then click Open Anyway again.

This message means the app is not signed by a paid certificate. It is not a virus warning. More in Is the install safe?

#Step 3: Copy it to Applications

1. Drag Vyapzio onto ApplicationsIn the same window, drag the Vyapzio icon onto the Applications folder next to it. This copies the app; the disk image can then be ejected.
2. Open itOpen Applications in Finder and double-click Vyapzio, or press Cmd + Space, type Vyapzio and press Return.

#Step 4: Create the owner account and activate

1. Create the owner accountThe first screen asks for a name, email and password. The account stays on this Mac and controls who can open the books.
2. Enter the licence keyPaste the key from your purchase email and click Activate this computer.
3. Check the confirmationThe app confirms the licence and lists this Mac as the first device.

No connection, or the server cannot be reached? Activation needs the internet once. Try again, then email contact@vyapzio.in with the key and the message shown. After activation the app works offline for 30 days between checks.

#Where your books are kept

Your books and saved PDFs live in:

~/Library/Application Support/vyapzio/books

To open it in Finder, choose Go → Go to Folder… and paste that path. Nothing is uploaded by itself. Back up from Settings → Backups; see Backups.

#Removing the app

1. Back up firstIn Vyapzio, open Settings → Backups and export a backup.
2. Quit and deletePress Cmd + Q in Vyapzio, open Applications in Finder, drag Vyapzio to the Bin and empty it.

Your books in ~/Library/Application Support/vyapzio/books are kept so a reinstall finds them. Delete that folder yourself only if you want the data gone. Uninstalling does not free the licence.

#Every day after that

Open Vyapzio from Applications, Launchpad or the Dock. Closing the window quits the app; your books are saved as you go.
