Weather Station for Mac: 13 Maker Apps, 0 Built for macOS
If you're shopping for a weather station for a Mac, don't expect the station maker to provide the Mac software. On 2026-10-23 I read the App Store listings for the 13 official apps from eight station brands: Ecowitt, Ambient Weather, AcuRite, La Crosse, WeatherFlow (Tempest), Davis, Netatmo and Sainlogic. None of them is built for macOS. Twelve reach a Mac only as iPhone or iPad apps that Apple lets run on M-series chips, and Netatmo's isn't offered on the Mac at all. Davis and AcuRite both made Mac desktop software and both have dropped it. The Mac software that does work comes from independent developers. I ran two of those programs on this M4 Mac mini and checked a third installer file by file.
What I didn't do: I own no weather station. The App Store data, the installer checks and the two programs I ran are my own work from today. Hardware behavior, such as USB loggers dropping out or rain gauges miscounting, comes from owner threads and vendor pages, linked where it appears.
The maker apps: 0 of 13 built for macOS
An Apple Silicon Mac can run an iPhone or iPad app unless the developer opts out. The App Store page shows this in its Compatibility block. A native Mac app says "Mac: Requires macOS 11.0 or later", and an iPad app allowed on the Mac adds "and a Mac with Apple M1 chip or later". I used the same reading for the thermal camera for Mac census.
| Brand | App | On a Mac (App Store, 2026-10-23) |
|---|---|---|
| Ecowitt | Ecowitt, WSView Plus, WS View | iPad app, M1 or later (all three) |
| Ambient Weather | Ambient Weather Network, awnet, AmbientTool | iPad app, M1 or later (all three) |
| AcuRite | AcuRite NOW | iPad app, macOS 12.2 and M1 |
| La Crosse | La Crosse View | iPad app, M1 or later |
| WeatherFlow | Tempest Weather, TempestOne Weather | iPad app, M1 or later (both) |
| Davis | WeatherLink | iPad app, macOS 14.6 and M1 |
| Sainlogic | Sainlogic | iPad app, M1 or later |
| Netatmo | Netatmo Weather | Not offered on Mac |
Two things follow. An Intel Mac gets none of these apps. And a listing isn't proof that an app works: this Mac mini has no Apple Account, so I couldn't install any of them. Setup is where an iPad app on a Mac is most likely to fail, because a phone app that joins the console's own Wi-Fi network or uses Bluetooth expects iPhone hardware. Plan to do first-time setup from a phone and use the Mac for viewing.
One listing shows how long dead apps can linger. AmbientTool is still on the store, and still offered on the Mac, but its own description says it was discontinued on January 31, 2023. It was the setup app for WS-2902 consoles sold from December 2016 to May 2018. Ambient says those consoles can't rejoin its network after a Wi-Fi reset, and that the newer WS-2902D connects through a web browser with no app.
The desktop software, checked on an M4
Davis and AcuRite both used to ship Mac software. According to a UK Davis distributor's knowledge base, the last WeatherLink for Mac release was v6.0.3 in July 2015, and the page calls it obsolete. It points Mac users to WeatherCat, Cumulus MX and Weather Display. AcuRite's end-of-life notice says it stopped supporting PC Connect for Mac on February 28, 2019. A third Mac-only app, WeatherSnoop, is gone too: its domain, tee-boy.com, now redirects to a domain-for-sale page.
Here's what is left and what I found:
- WeeWX 5.5.2 (free, Python). It installed with pip into a virtual environment on the Python 3.9.6 that ships with Apple's command line tools. The Pillow wheel it pulled was arm64. With the built-in simulator driver it wrote its first archive record and a 67-file HTML report with charts 21 seconds after launch, at 44 MB of memory. It has 13 drivers built in, mostly for USB and serial consoles (Davis Vantage, AcuRite, Fine Offset USB, WMR, WS23xx/28xx). Ecowitt gateways, Wi-Fi consoles and Tempest need third-party extensions.
- Cumulus MX 5.1.6 (free, released 2026-09-17). It's a .NET 10 program, not a Mac app. The zip ships arm64 native libraries for macOS. With Microsoft's .NET 10.0.13 runtime for arm64 it started, served its admin page on port 8998 (HTTP 200) and sat at about 122 MB waiting for a station type.
- WeatherCat 3.3.2. The download is named WeatherCat333.dmg, but the bundle inside says 3.3.2. The app is universal and notarized. Of the 25 Mach-O binaries inside, 23 are universal. The two Intel-only ones are the updater and the SQL driver plugin. The WeatherCat FAQ confirms the SQL driver is removed on M-series Macs, with Rosetta as the workaround. Its station list covers Davis, La Crosse WS23xx, Oregon Scientific and Fine Offset USB consoles. Ecowitt gateways and Tempest aren't on it.
- Weather Display ($30.99 on the Mac App Store, version 436, updated 2026-10-22, macOS 11 or later). It's a native Mac listing. I didn't buy it.
- UnderTheWX (free on the Mac App Store). It's a menu bar app for five AcuRite USB stations and was last updated 2021-04-17.
WeeWX tripped me once. I first passed the config file as a relative path, and the report thread died with FileNotFoundError: ... weewx-data/weewx-data/skins/Seasons, because the root directory got resolved twice. With an absolute path it worked first time:
python3 -m venv ~/weewx-venv
~/weewx-venv/bin/pip install weewx # 5.5.2 on 2026-10-23
~/weewx-venv/bin/weectl station create ~/weewx-data --no-prompt # simulator driver
~/weewx-venv/bin/weewxd --config ~/weewx-data/weewx.conf # absolute path
# report lands in ~/weewx-data/public_html/index.htmlRunning it as a background service is a separate step, and owners have hit trouble there. In WeeWX issue #625 (2020), an M1 owner couldn't start it from launchd until a dead Python symlink was fixed. Issue #971 (2024) reported that the 5.1.0 macOS daemon instructions and the plist they generated were wrong. If you want it running 24/7 on a Mac mini, the Mac mini as a 24/7 server post covers the power and restart settings I use for my own always-on jobs.
The connection matters more than the app
Owners' complaints about weather stations on Macs are mostly about USB. A Vantage Pro 2 owner on the Mac Power Users forum said the USB logger "requires a third party serial to USB driver that seems to require updating for each major macOS version", that logging hadn't been reliable, and that Davis's own Mac software was "unusable". WeatherCat's FAQ tells Davis owners to install the Silicon Labs driver and warns that the logger is "particularly prone" to driver faults that call for a reboot. macOS has its own driver for some Silicon Labs chips (see USB to serial adapter for Mac), but I didn't check which ID Davis's logger reports.
Stations that put their data on the network avoid all of that, and any software on the Mac can read them. Ecowitt's Wi-Fi gateways answer a local LAN API, which the Ecowitt Gateway driver for WeeWX polls. Tempest broadcasts UDP on the local network. In a 2019 Tempest forum thread, a WeeWX user noted that the UDP driver means "you don't even need to worry about usb/serial", and the Weather Display author said the Mac version already worked with Tempest. Ambient's Wi-Fi consoles can send to a custom server, and the weewx-interceptor driver listens for exactly that.
One caveat: the original repository for the Ecowitt Gateway driver (github.com/gjr80/weewx-gw1000) returned 404 when I checked today, and copies live under other accounts. Check that you're installing a maintained copy.
What to buy, and what owners complain about
As an Amazon Associate I earn from qualifying purchases. Prices are amazon.com with a New York 10001 delivery address on 2026-10-23, and they will move. I haven't used either station. The specs come from the listings and the problems from owner and vendor reports.
The Ecowitt Wittboy GW2001 ($199.99, 4.1 stars from 209 ratings) pairs the GW2000 gateway with the WS90 seven-in-one sensor. The gateway is the reason to pick it for a Mac. It has the local API above, which WeeWX can poll, and the native Mac app Weather Info for Ecowitt (macOS 26 or later) reads it through an Ecowitt cloud share link. The WS90 counts rain with a haptic sensor, not a tipping bucket. A Tempest owner traced serious over-reporting on that kind of sensor to vibration from a loose mast. That's a different station, but if your mount shakes, expect the same risk.
The Ambient Weather WS-2902 ($199.99, 4.4 stars from 13,158 ratings) is the most-reviewed station I found. It has no USB, so all its data leaves over Wi-Fi to Ambient's network, Weather Underground or a custom server. The listing doesn't say which console revision ships. That matters because of the AmbientTool shutdown above, so check the label on the console. One warning from the Mac Power Users owner applies to any backyard rain gauge: they cited CoCoRaHS, a volunteer rain network, saying personal stations undercount rain by "sometimes 25% or more".
FAQ
Is there weather station software for Mac?
Yes, but it comes from independent developers, not the station makers. WeatherCat is a universal Mac app for Davis, La Crosse, Oregon Scientific and Fine Offset consoles. Weather Display is $30.99 on the Mac App Store. WeeWX and Cumulus MX are free and run on Apple Silicon. WeeWX runs under Python, and Cumulus MX needs Microsoft's .NET 10 runtime.
Do Ecowitt and Ambient Weather apps work on a Mac?
Their apps are iPhone and iPad apps that the App Store offers on Apple Silicon Macs (M1 or later). Intel Macs can't run them. They aren't built for macOS, and setup may still need a phone. Ecowitt gateways also expose a local LAN API that WeeWX can poll, and the native Mac app Weather Info for Ecowitt reads a station through an Ecowitt share link.
Does Davis WeatherLink work on a Mac?
The old WeatherLink desktop software for Mac stopped at v6.0.3 in 2015 and is obsolete. The WeatherLink iPad app is offered on Apple Silicon Macs with macOS 14.6 or later. To log a Davis console to a Mac directly, owners use WeatherCat or WeeWX with the USB logger and a Silicon Labs serial driver.

Method: on 2026-10-23 I read the Compatibility block of 23 App Store pages (13 official apps from eight station brands, 10 independent apps found by App Store search) with a desktop Safari user agent. I installed WeeWX 5.5.2 with pip and ran it with the simulator driver. I ran Cumulus MX 5.1.6 build 5016 on Microsoft's .NET 10.0.13 arm64 runtime with no station configured. I mounted WeatherCat333.dmg and ran lipo -archs on every Mach-O file in the bundle, plus spctl for notarization. All of this was on a Mac mini M4 running macOS 26.4.1, with no station attached. The Davis Mac history comes from an archived Davis distributor knowledge base page, and AcuRite's from its support article. Owner reports come from a Mac Power Users thread, two Tempest community threads and WeeWX issues #625 and #971. Amazon prices and ratings were read from product pages the same day.
