Duck typing moment
You're not wrong, but it bugs me when my ratio drops, so I always seed everything I download. I have a pretty good internet service though.
My stats:

Maybe it's still using the borked config because all sessions were not exited? Try exiting it and then make sure no tmux process is still running, by for example running ps -aux | grep tmux.
Otherwise there must be some tmux config still lying around in your $HOME.
Edit: I don't know anything about Macs so I'm just assuming it works similar to linux.
Does fzf search hidden folders? You could also try with this, to make extra sure: find $HOME -name "*tmux*".
That's OK, we all got our own preferences 😉 But I think you will be pretty good to go on t495. It has apparently been linux certified on older Ubuntu, which Mint is based on.

Also linux certified by Lenovo:

nam is assigned the value returned by input.
This is not some edge case behavior by the input function. This is always how function calls work. You can think of it like substituting input('Who are you? ') with the value returned by it, which is the string typed in by the user in this case.
Drop oh-my-zsh and look for something else to customize your prompt. I like Powerlevel10k but Starship is good too.
Somebody should write a python to javascript transpiler for the web...
(please don't actually do that)
