I am running a Mac M1. I followed the instructions on installing mavsdk. I get the following issue:
Traceback (most recent call last):

A few weeks ago, I was able to run this file without any issues. Can someone point me in the right direction to resolve this?
When I use pip3 show mavsdk it shows that I have version 0.12.0. I see that the latest version is 1.4.9. I tried installing another version using pip3 install mavsdk==1.4.9 and get the message:
ERROR: Could not find a version that satisfies the requirement mavsdk==1.4.9 (from versions: 0.5.2, 0.7.0, 0.8.0, 0.8.1, 0.8.2, 0.9.0, 0.9.1, 0.10.0, 0.11.0, 0.12.0)
ERROR: No matching distribution found for mavsdk==1.4.9
I have not made any updates, have not installed anything new. I have tried running the examples in a venv. I have used pycharm, vscode, terminal, and the same issue happens.
So on the mac python 3.11.1 is installed, but in the venv in pycharm Python 3.9.6. I also noticed that when I did the mavsdk install, protobuf 4.21 was installed. So I uninstalled that one and installed protobuf 3.20.3
I am using the logfiles_download.py file to test. So the above errors seem to be gone. Now I get the following information when I run the file.
This installation does not provide an embedded 'mavsdk_server' binary.
If you installed using pip, this means that 'mavsdk_server' is not distributed
for your platform yet (e.g. arm).
You will need to get and run the 'mavsdk_server' binary manually:
1. Download 'mavsdk_server' from: https://github.com/mavlink/mavsdk/releases
or build it from source.
2. Run it, e.g. on port 50051:
'./mavsdk_server -p 50051'
3. Set the 'mavsdk_server_address' and port when creating the System:
'drone = System(mavsdk_server_address='localhost', port=50051)'
I thought the mavsdk_server would automatically be installed.
I am running PX4 and MavProxy on Ubuntu 20.04 and using my Mac IP address:14550, which is also being used in logfile_download.py. If I am doing this, will this also require me to create the mavsdk port? When this was working a few weeks ago, I did not have to go through this process.
I don’t know the state of the included mavsdk_server_bin for macOS on M1. The problem is that there don’t seem to be M1 Macs available in GitHub Action CI machines, and I also don’t have one at home to try this.
When I run the server on the terminal inside PyCharm (after cd into the directory where it is placed) I get the following:
zsh: command not found: mavsdk_server_macos
What puzzles me is that back in December everything was working just fine and from one day to the next I started having all these issues. I had even written some code to get the yaw, pitch, and roll. I had tested the telemetry.py and logfiles_download.py and it worked. No errors like this at all.
mavlink on ubuntu side shows that partner IP is 127.0.0.1
and mavproxy.py has the following log:

Not sure if that has something to do with it.
Also, do you have a venmo or something similar so I can buy you a beer or something for all your help?
That’s ok, thanks. I’m planning to set up GitHub sponsors for MAVSDK maintenance at some point but that’s not done yet. And I’m sorry that the Python connection and debugging story is not straightforward at all, unfortunately.
