🚀 Telegraphica v0.4.5-beta — Open Beta

Telegraphica is an experimental native Telegram client for OS X 10.9.5
Mavericks on Intel x86_64. This is the first open beta: the app is now useful
enough for broader testing by people who want Telegram back on older Macs.

🚀 What Should I Download?

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

👉 Telegraphica-v0.4.5-beta-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

• Open beta release for OS X 10.9.5 Mavericks on Intel x86_64.
• Public builds fetch the Telegraphica TDLib app configuration automatically on
  first launch, so users should not need to enter Telegram API fields manually.
• Voice messages sent from official Telegram clients can now play through a
  bundled Mavericks-safe Ogg/Opus helper.
• Chat search/navigation is available from the native search field.
• Storage Usage shows cached data and can clear local cache without deleting
  Telegram cloud media.
• Pinned dialogs stay at the top and can be pinned or unpinned from the context
  menu.
• WEBP, TGS, and animated WEBM/VP9 stickers render in chats on Mavericks.
• The app keeps the previous chat, supergroup topic, media preview, reaction,
  notification, Dock badge, profile, settings, and update-checking features.

🔑 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-v0.4.5-beta-macos10.9-x86_64.dmg
• Telegraphica-v0.4.5-beta-macos10.9-x86_64.app.zip
• matching .sha256 files.

🔐 Security Notes

Public builds do not ship a plaintext TelegraphicaTDLibDefaults.plist with
Telegram API fields in app resources. On first launch, Telegraphica downloads
the app-level TDLib configuration from the Telegraphica bootstrap endpoint and
saves it locally on that Mac. User login state, TDLib databases, phone numbers,
login codes, 2FA passwords, and Keychain material remain local to each user's
Mac.

⚠️ Known Beta Gaps

• The app is unsigned/not notarized, so Gatekeeper may require right-click Open.
• Some sticker packs or GIF-like media can still expose edge-case playback or
  layout issues.
• Release confidence still comes from OS X 10.9.5 / Xcode 6.2 HITL testing.
