Why does terminal become unresponsive after I use certain git commands?

Very often (every time really) after I use the command git log my terminal becomes unresponsive to further input, this is on OSX. Is there a command that I don't know about that will开发者_JAVA百科 make the terminal active again instead of just quitting the terminal and starting over?

You are inside a program that displays the log without scrolling, most likely less, which can be exited by pressing the q key.

Just press q to quit from less.
