wheezy 7.2 terminal challenges

Using a mac 10.8.5 to access ssh on a newly installed wheezy 7.2 BBB

Tried three SSH clients
iterm2 (iterm.app)
chrome secure shell extension

iterm2 and terminal set to xterm-256colors. Terminal works okay with vi and mac osx arrow keys.

iterm2 and chrome extensions don’t behave when mac arrow keys are used and insert characters and new lines.

I abhore terminal and how I can use iterm2 or chrome extension.

Suggestions on what to do next?
