Yes, iTerm2 is one of the best macOS apps. It's the first thing we have new developers install if they're new to macOS.

On the 120Hz MacBook Pros, there's an advanced iTerm2 setting that lets you change the maximum frame rate to 120 or above (adaptive frame rate also needs to be disabled).

For monitors with a high refresh rate, it's worth checking out. You can see the difference by running:

  $ cat /dev/random | hexdump

I used it for a long time but switched back to regular Terminal for the lower latency, because I realized I couldn't even name an iTerm2 feature I used that Terminal didn't have. I'd just been using it because it was so widely discussed.

That's completely fair. For me the killer feature is it's multi-pane support. Being able to have several terminal panes side-by-side on screen at once without having to fiddle about with something like tmux is wonderful.

iTerm2 is pretty sluggish, has some memory leaks that I hit every now and then, and doesn't emulate some escape sequences correctly (bold, reset).

But it has Cmd+Shift+E, which I wish some other emulators I like would just wholesale copy that feature.

Honestly, it's one of the better emulators out there; it's my recommendation if you're otherwise stuck on macOS.
