Yesterday, I upgraded my Mac to Mac OS X 10.9 (Mavericks), and since then I couldn’t open the “Terminal,” each time I open a session, the following error is shown:
[Could not create a new process and open a pseudo-tty.]
[Command not found: tmux]
I don’t know what's causing this issue and a fresh restart and killing the relevant processes on activity monitor doesn’t help. Any thoughts?
