Verify what you downloaded
Auto-update checks a detached signature and refuses a build that does not match it. A file you download by hand is not checked for you, so compare its SHA-256 against the published list:
iPhone and iPad
The app is free and nothing is sold in it; updates come through the App Store, and the details are on its own page. It is not offered in France or mainland China.
First launch on a Mac
On a Mac with Apple silicon (M1 or later), Conchshell opens on the first launch; macOS only asks whether to open an app downloaded from the internet. The Intel build is not notarised yet, so on an Intel Mac, macOS refuses the first launch. On macOS 13 Ventura and later, open System Settings → Privacy & Security; on macOS 12 Monterey, System Preferences → Security & Privacy → General. Scroll to the message naming Conchshell and press Open Anyway. Once is enough — later launches and updates go straight through.
Install with Homebrew
On a Mac with Homebrew:
If Conchshell is already in Applications from the .dmg above, add --adopt after --cask. Conchshell keeps updating itself; brew upgrade --cask --greedy conchshell updates it through Homebrew instead. For the first launch on an Intel Mac, see “First launch on a Mac”.
