iTerm2 supports operating system features such as window transparency, full-screen mode, split panes, Exposé Tabs, Growl notifications, and standard keyboard shortcuts. Other features include customizable profiles, Instant Replay of past terminal input/output,[2][3] a Toolbelt showing running jobs and a command history,[4] the ability to open when a key combination is pressed,[5] and autocomplete.[6]
History
A Mozilla-sponsored 2019 code audit found one serious security vulnerability in iTerm2's tmux integration, which developer George Nachman fixed in an update.[7]
Reception
Software engineer Mike Rourke called it an "excellent [...] more full-featured Terminal" than Apple's built-in Terminal app.[4] iTerm2 is recommended in several programming books,[4][8][9][10] with engineer Jo Rhett and Mozilla's Tom Ritter describing it as one of the most popular terminal emulators.[11][12] Developer Mark McDonnel noted its additional features but criticized it for being less ubiquitous than tmux by lacking a Linux version.[13]
