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?
It might be a simple and going into Preferences/Startup/Shells open with and select 'Default login shell'.
It is related to where the Shell you are opening, and you can have multiply shells (but that is another thread'
I was getting similar error. So to fix it, within Terminal, I opened
Preferences > General
and set
'Shells open with': to 'Default login shell'.
I then quit and started the terminal app again and the error was gone.
Hope this helps.
I got this error after upgrading from Lion (10.7) to Mavericks. (10.9) This fixed it: Go to Terminal > Preferences > Settings > Shell and uncheck "Run command".
Do this terminal>preferences>general>shells open with then click on "default login shell"
If above answers not fixing the problem
For BigSur OS: Systempreference > Sharing > Remote Login (check the box) - this will allow port 22 to connect remote hosts via SSH.
As @user279065 mentioned, selecting 'Default login shell' might resolve this issue
thats step 1:
but depending on what shell you have as default you may still face another issue like this
So to fix that you have to do this (step 2):
/binand/usr/binetc., if you installed software there, it's now gone.tmuxwhen opening the Terminal, instead, run a shell likebash.
