Is there a free WiFi analyzer for Mac?

Yes. NetworkBolt WiFi Analyzer is a free WiFi analyzer for Mac with Apple Silicon. Download the DMG, install the app, and scan nearby networks to see channel congestion.

Does this WiFi analyzer work on Apple Silicon?

Yes. Version 1.0 is built natively in Swift for Apple Silicon Macs (M1, M2, M3, M4, and later). Intel Macs are not supported in this release.

What is a Mac WiFi congestion tool used for?

A Mac WiFi congestion tool shows how crowded nearby WiFi channels are. NetworkBolt WiFi Analyzer graphs overlapping networks on 2.4 GHz, 5 GHz, and 6 GHz so you can pick a clearer channel and improve wireless performance.

Can I scan 2.4 GHz, 5 GHz, and 6 GHz WiFi on Mac?

Yes. The graph view lets you switch between 2.4G, 5G, and 6G bands. The list view shows every nearby network with channel, band, signal strength, and security type.

How do I install WiFi Analyzer on macOS?

Download WifiAnalyzer-1.0.dmg, open the disk image, and move the app to Applications. On first launch, macOS Gatekeeper may ask you to allow the app under System Settings → Privacy & Security. Grant WiFi or Location access if prompted so scans can run.

Why use a WiFi analyzer on Mac?

Crowded channels cause slow speeds and dropouts. A dedicated Mac WiFi analyzer shows what your router settings alone cannot.

See congestion clearly

Visualize how crowded nearby WiFi channels are so you can pick a cleaner channel for your network.

Overlapping networks

Identify neighbouring networks that compete on the same channels and drag down performance.

WiFi analyzer for Mac (Apple Silicon)

Looking for a free WiFi analyzer for Mac that actually runs on Apple Silicon? NetworkBolt WiFi Analyzer is a native Swift app for M1, M2, M3, and M4 Macs. It scans nearby WiFi networks and shows channel congestion visually. There is no Intel compatibility layer and no subscription.

Unlike generic network utilities, this Mac WiFi congestion tool focuses on what matters for home and small-office wireless: overlapping SSIDs, channel width, signal strength in dBm, and which band (2.4 GHz, 5 GHz, or 6 GHz) each network uses.

Mac WiFi congestion tool that shows overlapping channels

When many routers share the same channel, throughput drops. WifiAnalyzer graphs each network as a curve across channels so you can spot crowded spots at a glance, for example a busy channel 6 on 2.4 GHz or overlapping 80 MHz blocks on 5 GHz.

Use the list view as a WiFi channel scanner for Mac: sort by signal, filter by band, and check security (such as WPA3) before you change your access point settings.

How to pick a clearer WiFi channel on macOS

Download and install WifiAnalyzer-1.0.dmg
Open the app and run a scan of nearby networks
Compare 2.4G, 5G, and 6G graph views for the least overlap
Change your router to a quieter channel, then scan again to confirm
