Requirements

Before you begin, confirm that your release and external services are ready.

Computer and browser

• Use a release and operating system explicitly supplied as supported by Cantero Madera support.
• Install the current official Google Chrome Stable release in its standard location.
• Allow Cantero Madera to open normal, visible Chrome windows.
• Make sure the operating system’s secure credential storage is available.
• Keep enough free disk space for persistent Chrome profile data and run artifacts.

This guide currently covers the qualified macOS release. Do not assume a Windows installer is production-supported unless your download or support instructions say so explicitly.

Cantero Madera does not use Chrome Beta, Dev, Canary, Chromium, Chrome for Testing, a custom Chrome path, or an alternate browser fallback.

Accounts and services

Every profile requires a saved authenticated proxy. Automated signup also requires:

• TextVerified credentials with enough balance for a verification if Amazon requests one;
• a mailbox provider shown as Available in the profile form; and
• permission to grant the app read-only mailbox access.

A complete Billing Profile is required before automated Prime enrollment and checkout can proceed.

Caution

Prime enrollment and checkout can create real charges. Use only accounts, proxies, mailboxes, and payment methods that you are authorized to control.

Network access

Allow outbound access for licensing, Chrome, Amazon, the selected mailbox provider, TextVerified when used, update checks, and the proxy endpoint. A firewall, content filter, or captive portal can prevent profile admission even when ordinary browsing appears to work.
