Here's my tmux.conf

Thanks for the report. Can you check if the following patch to fzf-tmux helps?

Nice fix! That seems to have done the trick. Thanks again!

[junegunn]

Great, thanks for your assistance, I'll push the fix to master.

Updated fzf-tmux to inherit the TERM value of the hosting shell and also updated fzf to gracefully stop on invalid $TERM. If you used Homebrew to install fzf, you can brew reinstall fzf --HEAD.
