Telegraphica v0.4.1-alpha.2 ✦ First Public Alpha

Telegraphica v0.4.1-alpha.2 — First Public Alpha ✦

Telegraphica is an experimental native Telegram client for OS X 10.9.5
Mavericks on Intel x86_64. This alpha is intended for real legacy-Mac testing:
sign in, read chats, send messages, preview media, and collect feedback from
older Macs that modern Telegram clients no longer support.

🚀 What Should I Download?

If you just want to install Telegraphica, download this file from Assets:

👉 Telegraphica-v0.4.1-alpha.2-macos10.9-x86_64.dmg

Then open the DMG and drag Telegraphica.app into Applications.

The .app.zip file is an alternate app bundle package. The .sha256 files are
for checksum verification. You do not need them to install Telegraphica.

✨ Highlights

• New users can proceed to the regular Telegram sign-in flow without manually
  entering api_id and api_hash when the release app is built with bundled
  Telegraphica app credentials.
• Local user config still wins when present, so developer/test Macs can override
  the bundled defaults.
• Release builds now sanitize the bundled TDLib config: only api_id,
  api_hash, tdlib_parameters_schema, and use_test_dc are copied into the
  app bundle.
• No Telegram phone numbers, login codes, 2FA passwords, TDLib sessions, or
  databases are copied into the app bundle.
• Includes the current native chat, media, notification, profile, settings, and
  update-checking alpha feature set.

🔑 First Launch

1. Download the .dmg file.
2. Open it and drag Telegraphica.app into Applications.
3. If macOS blocks the app, right-click / Control-click it and choose Open.
4. Sign in with your Telegram phone number, login code, and 2FA password if
   needed.

📦 Release Files

• Telegraphica-v0.4.1-alpha.2-macos10.9-x86_64.dmg
• Telegraphica-v0.4.1-alpha.2-macos10.9-x86_64.app.zip
• matching .sha256 files.

🔐 Security Notes

The bundled config contains app-level Telegram API credentials only. User login
state, TDLib databases, phone numbers, login codes, 2FA passwords, and Keychain
material remain local to each user's Mac.

⚠️ Known Alpha Gaps

• Sticker and GIF rendering is still incomplete and can fall back to emoji.
• The app is unsigned/not notarized, so Gatekeeper may require right-click Open.
• Release confidence still comes from OS X 10.9.5 / Xcode 6.2 HITL testing.
