Under Terminal > Preferences... > (Profile) > Advanced, "Declare terminal as:" should be set to xterm-256color
.
This is easy with homebrew:
brew install screen
When this finishes you'll have a new binary in /usr/local/bin/screen
.
Add /usr/local/bin
to the front of your $PATH
so that your shell uses this binary, and not the one in /usr/bin
(you can confirm that it's using the correct one with which screen
). If you're using the bash, this goes into your .bash_profile
:
PATH="/usr/local/bin:$PATH"
If you're using another shell, then you probably already know where this goes. :)
BTW, the terminal type should be
xterm-256color
. Also IIRC, Terminal does indeed support 256 colors - you can test it yourself by copying and pasting the Perl script here into Terminal (if it works outside of screen but not inside it then you know its not Terminal).
