Thermal Camera for Mac: 41 Vendor Apps, None Built for macOS
No thermal camera maker I could find ships a native macOS app. I went through the App Store listings of 41 thermal-camera apps from 22 makers on 2026-10-20, and 30 of them are offered on Mac only because they are iPhone or iPad apps that Apple lets run on Apple Silicon. Every one of those 30 lists "a Mac with Apple M1 chip or later" as the requirement. FLIR, the biggest name in the category, has none of its three apps on that list. A search of the Mac App Store itself turned up no macOS app from any of the 22 makers. A thermal camera for Mac is still possible, but it comes down to one of three routes, and the cheapest one depends on a pixel format detail that wrecks the temperature data if you get it wrong.
Scope first. I don't own a thermal camera, and this Mac mini has no Apple Account, so I couldn't install any of the iPad apps. What I did: pulled the 41 App Store pages and parsed each one's compatibility block, searched the Mac App Store for 11 thermal terms (131 apps), downloaded the one open-source desktop viewer with a Mac build and checked its binaries on an M4 Mac mini running macOS 26.4.1, and wrote a small script that simulates what happens to a TC001-style data frame when it gets converted to RGB. How cameras actually behave on a Mac comes from vendor pages and owners' threads, linked where I use them.
Route 1: the maker's iPhone app, running on the Mac
Apple Silicon Macs can run iPhone and iPad apps if the developer allows it. The App Store shows that choice in each app's compatibility block, so it can be checked without a device. Here is how the 41 apps split.
Makers with at least one Mac-listed app: HIKMICRO, InfiRay, Raysen (Thermal P2), Seek Thermal, Guide (TargetIR and FocusIR), UNI-T (all four), Klein Tools, RIDGID, Testo, Topdon (ThermCam), Teslong, PeakTech, Mileseey, Foxwell, Pixfra, Athlon, NOCPIX and Vantrue. The makers with nothing on Mac are FLIR, Fluke and Yukon.
The listing is the easy part. Whether an iPad app running on a Mac can see a thermal camera is a separate question, and I couldn't test it. Cameras that talk to their app over Wi-Fi have the better odds, because the app only needs a network connection. USB-C dongles that plug into a phone are a different matter, and I found no owner report of one working through an iPad app on a Mac.
FLIR's absence is deliberate. In a 2021 EEVblog thread, an owner who wanted to run the FLIR Tools iOS app on an M1 Mac came back 16 days later: "it looks like Flir have blocked the IOS app from being able to run on the new M1 Macs." The same thread has FLIR support telling another owner that the Mac version of FLIR Tools was discontinued and to use the Windows software in a virtual machine. FLIR's FLIR Tools page now says "This product is discontinued" and points to Thermal Studio, whose plan page lists Windows 10 or 11 as the only supported systems.
Route 2: a USB camera that shows up as a webcam
The Topdon TC001 and InfiRay P2 Pro (USB-C version) present themselves as standard UVC cameras, the same class as an ordinary webcam for a Mac mini or a USB microscope on a Mac. macOS needs no driver to see them. Topdon doesn't claim Mac support, though: its TC001 product page says it "turns your Android smartphone/tablet or Windows laptop into a powerful thermal imager", and the desktop app it names, TCView, is for Windows.
The catch is in the frame. The TC001 sends a 256×384 YUYV image: the top half is a picture you can look at, and the bottom half is the 256×192 sensor's raw data, two bytes per pixel. Owners decode a pixel as (byte0 + byte1 × 256) / 64 − 273.15 to get degrees Celsius. That only works if those bytes reach your code untouched.
The open-source viewer most people start with, Les Wright's PyThermalCamera, was written for Linux. A Mac user asked for a port in January 2024, saying "Cameras aren't mounted with same path and I'm at a loss." The answers came two years later. In February 2026, one owner posted a version that works "on an M4 mac, python 3.14" by having ffmpeg capture the camera and pipe raw YUYV into the script, tested with a Topdon TS001. The script's own comment says it uses "ffmpeg pipe instead of cv2.VideoCapture for reliable avfoundation capture with raw YUYV data (preserves thermal data)". In April 2026, another owner published ThermaliZed, a Python GUI for Apple Silicon that talks to AVFoundation through PyObjC and lists the TC001 as tested. The capture line at the heart of the ffmpeg version:
ffmpeg -f avfoundation -framerate 25 -video_size 256x384 \
-pixel_format yuyv422 -i 0 -pix_fmt yuyv422 -f rawvideo -What an RGB conversion does to the temperatures
I wanted to know how bad it is when something in the chain hands you RGB instead of raw YUYV, so I simulated it. My script builds a 256×192 temperature field (a 21 °C room, a 65 °C hot spot, a 4 °C cold spot), packs it into YUYV bytes the way the TC001 does, runs a standard BT.601 YUYV-to-RGB conversion with 8-bit clipping, and then tries to recover the bytes from the RGB values.
Out of 49,152 pixels, 34,014 (69%) produced an RGB value outside 0 to 255 and got clipped. Only 15,298 pixels came back with the exact original bytes. The median error was 47.7 °C, and the worst was 152.6 °C. The reason is structural. At room temperature the high data byte sits around 73, far from the 128 that YUV treats as "no colour", while the low byte cycles through all 256 values as the temperature changes. With chroma that far off centre, most combinations push red, green or blue past the ends of the range. The picture still looks like a thermal image, because the top half is a real picture. Only the numbers are gone. This is a simulation of the conversion, not a measurement of AVFoundation's or OpenCV's exact code path, but it shows why the Mac ports above go out of their way to keep YUYV.
Route 3: the old Mac software, and why it doesn't run
The one open-source desktop viewer with a released Mac build is GroupGets' GetThermal, made for FLIR Lepton cores on PureThermal boards. Its last release, v0.1.4, dates from November 2018. I mounted the 26.8 MB disk image read-only: all 54 Mach-O files inside are x86_64 only, the app is unsigned, and spctl rejects it. On this Mac mini, which has no Rosetta, launching it fails with bad CPU type in executable. Apple says Rosetta stays available through macOS 27, so on a Mac that has it, the Intel build could still open. Owners' reports on top of that aren't encouraging: issue #32 (2020) shows no image on a Mac with a PureThermal 2 that worked on Windows, and in issue #46 a 2023 user running it under sudo still got uvc_open: Access denied (-3). The DJ world has the same Intel leftovers, which I counted in DJ controller software for Mac.
The other file-based option is newer. Rush Tools' Thermal Viewer, on the Mac App Store since June 2026, opens radiometric JPEGs from FLIR, InfiRay/P2 Pro and DJI, plus Fluke IS2 files, and recomputes temperatures when you change emissivity. It doesn't talk to a camera; you shoot on the camera or phone and analyse on the Mac. It had two ratings when I looked, so treat it as unproven.
What I'd buy
As an Amazon Associate I earn from qualifying purchases. For a Mac, I'd pick a USB camera that shows up as a webcam, because that route doesn't depend on any vendor's permission. The Topdon TC001 was $179.99 (list $249.99) and in stock with a New York delivery address on 2026-10-20, rated 4.6 stars. Its native sensor is 256×192; the Amazon title's "512x384" is upscaled. One Hacker News owner called it "significantly more responsive and higher resolution than similarly priced FLIR" options.
The downsides are real. Topdon doesn't list macOS, so the Mac software is community code with a handful of testers, and you'll be running Python or ffmpeg rather than a polished app. Owners of the related InfiRay P2 Pro report app-level gaps too: a long P2 Pro review found auto range switching "doesn't seem to work particularly well" and that there's no warning when the sensor is out of range. If you want an app that just works on the Mac, none exists from the makers yet. Like other capture cards on a Mac, a UVC thermal camera is only as good as the software reading it.
FAQ
Is there a thermal camera with Mac software?
No maker ships a native macOS app. On 2026-10-20, 30 of 41 thermal camera apps from 22 makers were offered on Apple Silicon Macs as iPhone or iPad apps, and FLIR, Fluke and Yukon had none. UVC cameras like the Topdon TC001 can be read on a Mac with community tools such as ThermaliZed or an ffmpeg pipe.
Does the Topdon TC001 work on a Mac?
Topdon only lists Android and Windows. The TC001 appears as a standard USB webcam, and owners have read its temperature data on Apple Silicon Macs with community code that captures raw YUYV through AVFoundation or ffmpeg. Converting the frame to RGB first destroys the temperature data.
Can I run FLIR software on a Mac?
Not natively. FLIR Tools is discontinued, its replacement Thermal Studio requires Windows 10 or 11, and FLIR's iPhone apps are not offered on Apple Silicon Macs. FLIR support has told owners to use the Windows software in a virtual machine.

How this was checked: on 2026-10-20 I searched the US App Store API for 10 terms (thermal camera makers and generic thermal terms), kept 41 apps whose developer is a thermal camera maker, and parsed the compatibility block on each apps.apple.com page; I also searched the Mac App Store entity for 11 terms (131 apps). I downloaded GetThermal v0.1.4 for macOS, mounted it read-only on an M4 Mac mini (macOS 26.4.1, no Rosetta, no Apple Account), ran lipo -archs on every file, checked codesign and spctl, and launched it once. The YUYV result comes from a Python simulation, not from a camera, and I installed no iPad apps. Owner reports are from one EEVblog thread, three GitHub issues, one review and one Hacker News comment, linked in place. The price is Amazon US with a New York address, read the same day.
