So you've downloaded Fifteen. Cool. Here's how to actually get it running on your Mac.<h2>Installing Fifteen</h2><ol class="steps-list"><li>Open the DMG file you downloaded. You'll see the Fifteen app icon and your Applications folder.</li><li>Drag Fifteen into Applications. Takes like 2 seconds.</li><li>Open Applications and double-click Fifteen to launch it.</li><li>Important: macOS will probably yell at you about the app being from an "unidentified developer" the first time. Don't panic. Right-click (or Control-click) on Fifteen and select "Open" from the menu. Click "Open" again in the dialog. You only have to do this once.</li><li>When you first open Fifteen, you'll need to connect your Telegram account. The app stores everything locally on your Mac - no cloud, no servers storing your messages.</li><li>Enter your phone number and Telegram will send you a code. Type it in. If you have two-factor auth enabled (you should), you'll need to enter that password too.What happens next</li><li>After you authenticate, Fifteen starts indexing your messages. This means it's pulling all your Telegram history and storing it locally so you can search through it later.</li><li>The first sync takes a while depending on how many messages you have. Grab a coffee. It runs in the background so you can keep using your computer.</li></ol><h2>Using Fifteen</h2>Navigation and actions heavily rely on the command palette (⌘K), which this you can:<ul class="accent-bullets"><li>Browse all your chats in the sidebar.</li><li>Search through messages with ⌘K.</li><li>See your full message history even when offline.</li><li>Connect to LLMs.</li><li>Send Broadcasts and maintain Audiences.</li><li>Automate away your social life.</li></ul>
