macOS has ncurses version 5.7 which does not ship the terminfo description for tmux. There're two ways that can help you to solve this problem.
Instead of tmux-256color
, use screen-256color
which comes with system. Place this command into ~/.tmux.conf
or ~/.config/tmux/tmux.conf
(for version 3.1 and later):
#256 colors in putty, tmux/screen and vim There is a detailed answer on stackoverflow. If you are looking for a short one, here it is.
putty
Set Connection -> Data -> Terminal-type string
to xterm-256color
tmux
Add this line to ~/.tmux.conf
This is a bash script that will automatically turn your wifi off if you connect your computer to an ethernet connection and turn wifi back on when you unplug your ethernet cable/adapter. If you decide to turn wifi on for whatever reason, it will remember that choice. This was improvised from this mac hint to work with Yosemite, and without hard-coding the adapter names. It's supposed to support growl, but I didn't check that part. I did, however, add OSX notification center support. Feel free to fork and fix any issues you encounter.
Most the credit for these changes go to Dave Holland.
