iTerm2 is the only software that keeps me on macOS. The tmux control mode is godsend. I’m afraid of the day that Apple makes macOS so bad that I have to switch.
Same here. Actually, it's not the only one keeping me on macOS but so far every time I thought about switching, the lack of a good terminal with control mode has had veto power.
Tmux control mode was contributed by the iTerm2’s author and so far no other terminal has implemented this. Every time I see a new terminal emulator, I immediately check for this functionality.
