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

Based on this:

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]

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?

MyHost ~ % openssl version
LibreSSL 3.3.6
MyHost ~ % openssl enc -help 2>&1 | grep gcm
 -aes-128-ecb              -aes-128-gcm              -aes-128-ofb             
 -aes-192-ctr              -aes-192-ecb              -aes-192-gcm             
 -aes-256-ctr              -aes-256-ecb              -aes-256-gcm             

[postlund]

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

[postlund]

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

[Jon-G-Max]

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]

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.
