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.[6]
Reception
Software engineer Mike Rourke called it an "excellent [...] more full-featured Terminal" than Apple's built-in
Terminal app.[3] iTerm2 is recommended in several programming books,[3][7][8][9] with engineer Jo Rhett and Mozilla's Tom Ritter describing it as one of the most popular terminal emulators.[10][11] Developer Mark McDonnel noted its additional features but criticized it for being less ubiquitous than
tmux by lacking a Linux version.[12]
