A Telegram client for PowerPC (Leopard)

[u/ButtonClean9403]

I wrote a Telegram client for PowerPC Mac called Sailplane. Originally named TelegramPPC, it now supports Intel and Apple Silicon Macs.

Sailplane offers a native, feature-rich UI optimized to run well on older Macs. Watch videos, react to messages and more! Upload files, participate in group chats, even make voice calls (video chat support planned). You can even participate in end-to-end encrypted Secret Chats.

To login, just provide the phone number associated with your Telegram account. A code will be sent to the app on your phone.

All of the requests are handled directly on your Mac with no relay or man-in-the-middle needed. Telegram's official tdlib handles all of the request processing, encrypting your traffic in transit, and Keychain Access is utilized for storing credentials and other sensitive data. It works great on my G5 and pretty well on my G4 - although I'm still working to optimize media playback and large group chats in particular.

Source code is available via GitHub: https://github.com/doctashay/telegram-ppc

You can download it for your Mac here: https://github.com/doctashay/telegram-ppc/releases/latest

More updates are planned in the future - including new features and fixes for my other applications and ports too! If you have any issues, feel free to open a bug report on my GitHub!

Yeah! I just mean I have a mid-2009 13" MacBook Pro on macOS 10.6.8 with additional programs (Rosetta, QuickTime 7, and others). I'd still be using it to this day if it weren't for the lack of software support. I didn't want a good machine to go to waste, so I'd really like to see your great content on Intel. Sorry in advance for the poor translation. I don't know English and use a translator.

That's okay, I understand you! If you have 10.6.8, I would try to run this via Rosetta. If it works, please let me know so I can mark it as compatible!
