iTerm2[2] and I'm astonished there's less mention of it on this thread (though there is some). That is mainly because I switched mostly to Linux a few years ago, and you'd think the lack of a good terminal app wouldn't be the biggest pain point of switching from Mac to Linux, but it absolutely is. There's no terminal app on Linux even close to as good as iTerm2. [2]: https://iterm2.com/ but it's v3 tho ¯\_(ಠ_ಠ)_/¯
The reason is that there was a recent controversy[0]. Many people have moved to alacritty/kitty/wezterm. [0]: https://news.ycombinator.com/item?id=40432446
I noticed the AI feature in the latest update to iTerm2, but it wasn't turned on by default, and I didn't turn it on, so...
