Installation, Compatibility & Usage Instructions

System Requirements (itemprop="operatingSystem")

AirRadar supports macOS 10.13 (High Sierra) through macOS 14 (Sonoma). It runs natively on both Intel‑based Macs and Apple Silicon (M1/M2) devices, thanks to universal binary packaging.

Step‑by‑Step Installation

1. Visit the official AirRadar download page and click the Download for macOS button.
2. Once the .dmg file finishes downloading, open it to mount the disk image.
3. Drag the AirRadar icon into your Applications folder.
4. Launch AirRadar from the Applications folder. macOS may ask to confirm the app is from an identified developer – click Open.
5. The first launch triggers a one‑time permission request to access your Wi‑Fi hardware. Approve this request to enable scanning.
6. AirRadar will check for updates automatically; you can also manually trigger an update from the Help → Check for Updates menu.

How to Use AirRadar Effectively

After launching, you’ll see three main tabs: Scanner, Favorites, and Filters. Press the Start Scan button on the Scanner tab to begin. Networks appear with columns for SSID, BSSID, channel, security type, signal strength, and noise level. Click any network to view detailed information, including encryption method and MAC address.

To add a network to your Favorites, select the entry, click the ★ icon, and confirm. Favorites appear in a separate tab for instant connection – just double‑click the entry and AirRadar will handle the authentication using the stored password from your Keychain.

If you wish to hide certain networks, switch to the Filters tab, click Add Filter, and specify criteria such as “Signal < 30 dB” or “SSID contains ‘Free‑WiFi’”. Saved filters automatically apply to each new scan, keeping your list tidy.

The graph panel at the bottom updates live, displaying signal (green) and noise (red) trends. Use this visual cue to decide which network offers the best stability, especially in crowded environments where signal strength alone can be misleading.
