Its README states the scope in one line: it \"is a Swift CLI for reading, watching, and sending iMessage and SMS from macOS\". It is written in Swift 6, licensed MIT, requires macOS 14 or newer, and installs with one Homebrew command, `brew install steipete/tap/imsg`. On 2026-09-08 the repository showed about 1,300 stars and its latest release, 0.15.3, was published the day before.",

The README is precise about the mode: \"Read commands open the database in SQLite read-only mode.\" Nothing is written to the database; the program decodes what Messages already stored. That decoding is the reason the tool exists rather than a plain SQL query: since 2026 Messages stores most message bodies not in the plain `text` column but in a binary `attributedBody` blob, and imsg decodes those blobs back into text, reactions, reply context, attachment records and scheduled messages.",
