The above exception was the direct cause of the following exception:

I assume OpenSSL is built without support AES GCM. This is the default installation of Python in macOS, right? Not installed via brew?

Jon-G-Max · 2024-07-17T20:41:07Z

This is macOS Sonoma 14.5. Not sure what comes preinstalled as default... Ran these commands.... Is there a URL you can suggest to install missing components?

How did you install pyatv? I would recommend installing in a virtual environment. Looks to me like the cryptography library is quite old.

postlund · 2024-07-29T18:00:59Z

Can you try to install from master and see if you notice any difference?

Jon-G-Max · 2024-07-29T21:56:20Z

I apologize but I'm really a newbie to open source, command line development. I have a stock MacBook Pro running Sonoma 14.5. Is there a step by step instruction on how to install from master ? My install used pip. I would really love to get this running but I don't want to waste anyone's time.

postlund · 2024-07-31T15:02:00Z

I'm planning on making a new release quite soon, just waiting for some things to land. I'll let you know when it's ready, then you can just upgrade with pip.

Jon-G-Max · 2024-09-05T18:35:19Z

Any updates? running "pip install pyatv" followed by "atvremote wizard" still results in the same errors.

I'm trying to use a Mac to control an Apple TV GUI.

No progress I'm afraid. My recommendation is to instal home-brew and install python from there instead. That's what I do and it works.
