Installation, Setup, and Compatibility

Installing Coinverter on your Mac is a straightforward three‑step process. First, download the latest DMG file from the official website or the Mac App Store. The download size is under 15 MB, making it quick even on slower connections. Once the DMG mounts, simply drag the Coinverter icon into your Applications folder. macOS may prompt you to confirm that you trust the developer; click “Open” to complete the installation.

Upon launching the app for the first time, Coinverter will request permission to access the internet to fetch the most recent exchange rates. Granting this permission is essential for the real‑time update feature. The initial setup wizard walks you through selecting your base currency, adding any favorite currencies to the quick‑access panel, and configuring the automatic refresh interval. All preferences are saved in the app’s sandboxed container, so they persist across macOS updates.

Supported Operating Systems: Coinverter runs on macOS 10.15 (Catalina) and later, including macOS 11 (Big Sur), macOS 12 (Monterey), macOS 13 (Ventura), and macOS 14 (Sonoma). Both Intel‑based Macs and Apple Silicon (M1, M2, and newer) are fully supported, with the app automatically selecting the appropriate architecture at launch.

For power users, Coinverter offers a command‑line interface (CLI) bundled within the app package. By opening Terminal and typing /Applications/Coinverter.app/Contents/MacOS/coinverter-cli, you can perform quick conversions without opening the GUI, which is handy for scripting or automating workflows.

Updating Coinverter is hassle‑free. When a new version is released, macOS will notify you via the App Store (if installed from there) or you’ll see an in‑app banner prompting you to download the latest DMG. The update process retains all your settings, ensuring a seamless transition to new features and security patches.
