Ever since updating my 15" Retina Macbook Pro to Mountain Lion 10.8.2, terminals become periodically non-responsive, activity monitor shows "Terminal Not Responding", and the color wheel sits and spins. This happens for as much as five to ten minutes sometimes, and doesn't seem to matter if I am running any jobs in the terminal or not. As well, nothing else except activity monitor is running at the time, and maybe command line tool support, though I believe that doesn't need to be running.


This is a huge problem, as I switched from Linux to Mac to work on, and I can't work if terminals are frozen all the time.

I could run five terminals at the same time on an old SUSE Atom processor box with heavy perl scripts running in all five, and not stutter the terminals or system, so what on earth could be causing the absolute fastest technology to be doing this?


Seems to be Mountain Lion related, and really have nothing to do with lack of resources or overloading, anyway.


A terminal inspection shows 6 recent hangs, and if I use a mouse to select text to cut-and-paste, I can make the problem repeat, even though it does it at other times.

What am I supposed to do here, call Apple Support, which I bought?

I need this resolved ASAP!
