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

[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.

[Jon-G-Max]

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.

[postlund]

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.

[oculist37]

Hi,

I'm a user from de 0.6 version. I wanted to make a clean install on a new Mac and I have exactly the same problem. I'm on Sonoma 14.7 and my AppleTV is 18.1. I tried your last advice : install a virtual environment, install home-brew, then install python from there, and install pyatv. So I have Homebrew 4.4.3, pip 24.3.1, atvremote 0.15.1 in my virtual environment. When I perform the wizard, I have also :

Do you have any idea or it's a problem with Sonoma ? or tvOS 18 ?

Thanks and no rush,

Best regards.

Edit 2 : may be a clue.
I tried the exact same procedure on a Mac running 14.6.1, and there were no issues with the installation or pairing with the wizard. I then copied the pyatv_venv folder directly to the Mac running 14.7, and the wizard successfully paired with this Mac as well.

I also tried creating a new pyatv_venv_beta directly on the same Mac running 14.7 and repeated the exact same steps. However, I encountered an issue with the installation of pyatv. Although the installation was reported as successful, when I use atvremote, I experience this problem: :

May be this is normal, and we can't install atvremote in two different venv.
