Install on macOS

The macOS build of Fexl Lite ships as a notarised universal DMG — one binary that runs on Apple Silicon and Intel Macs. Install once, then the in-app updater handles every release after that. macOS 12 (Monterey) or later required.

Install

1

Download the DMG

Open the link from your purchase email or grab it from downloads.fexl.io. The file is named Fexl-Lite-2.2.0-universal.dmg and weighs around 80 MB. Both Apple Silicon (M-series) and Intel are inside the same image — the installer picks the right slice automatically.

2

Open the DMG and drag the app to Applications

Double-click the DMG. Finder shows the Fexl Lite app on the left and an Applications shortcut on the right. Drag the app onto the shortcut. Eject the DMG when the copy finishes.

3

Open Fexl Lite from Launchpad

Press F4 or pinch-zoom on the trackpad to open Launchpad, then click Fexl Lite. You can also double-click it from the Applications folder, or pin it to the Dock for one-tap access during the day.

ⓘ

Gatekeeper on the first open

Fexl Lite is signed with an Apple Developer ID and notarised, so Gatekeeper accepts it without quarantine. If you see “Fexl Lite cannot be opened because Apple cannot check it for malicious software” — that’s a re-download from a non-notarised mirror. Right-click the app → Open → confirm in the dialog. Once you’ve done that the first time, it’s a regular double-click forever after.

Let the first launch finish

The app opens to the activation screen. From here the first-launch flow takes over — license key, owner PIN, store info wizard. Five minutes and you’re at the POS.

Updates

Fexl Lite uses the Tauri auto-updater. New releases announce themselves with a banner in the top-right of the app and download in the background; you accept the install on the next idle moment and the app restarts itself. No App Store, no Homebrew cask — the updater is built in.

✦

Pin the update channel in Settings

Settings → System → Update channel lets you choose Production (default — only stable releases) or Staging (early access, sometimes rough). Stay on Production for a register that handles real money. The channel is per-device, so a back-office Mac can run staging while the till runs production.

Uninstall

Drag Fexl Lite from /Applications to the Trash. That removes the binary but keeps your local database — the fexl.db file in ~/Library/Application Support/com.minib2c.pos/ is still there if you reinstall later. To delete the data too, also remove that folder. Do this only after you’ve exported a backup from Settings → System → Backup.
