INAV Configurator on Mac: 9.1.1 Unsigned, 10.0 RC Notarized
INAV Configurator does run natively on Apple silicon. The current stable build, 9.1.1, has an arm64 version, and it opened on this Mac mini (M4, macOS 26.4.1) without Rosetta. The catch is the signature. 9.1.1 carries only the ad-hoc signature that Apple's linker adds automatically. A downloaded copy gets the "is damaged and can't be opened" error, and on 2026-09-01 Homebrew disabled its cask for failing the Gatekeeper check. The first notarized INAV Configurator is 10.0.0-RC1. It's a release candidate, and it only talks to INAV 10 firmware.
I don't own an INAV flight controller, so nothing below comes from flashing or flying. On 2026-10-23 I downloaded four macOS builds and checked them on this Mac. I also ran the flight simulator (SITL) that ships inside the app, pulled all 88 releases from the GitHub API, and read the 37 issues in the configurator repo with "mac", "macOS", "OSX", "M1", "M2", "M4", "dmg" or "damaged" in the title. Owner reports in this post come from those issues.
Which INAV Configurator file to download for Mac
INAV has shipped three kinds of Mac build since 2017. The naming changed each time, which explains some of the wrong-file reports in the issue tracker.
For 9.1.1 on an M-series Mac, take INAV-Configurator_MacOS_arm64_9.1.1.zip or the matching .dmg. The x64 files are plain Intel code. On a Mac without Rosetta they fail with bad CPU type in executable, the same failure I got from the old 7.1.2 build. Mac owners have mostly worked this out. 84% of 9.1.1's Mac downloads were arm64, and Macs took 26.8% of all 9.1.1 downloads, against roughly 7 to 10% for most NW.js-era releases.
Here is what the four builds look like on disk:
| Build | Code | Signature | Gatekeeper (spctl) | Runs on M4 without Rosetta |
|---|---|---|---|---|
| 7.1.2 (NW.js, Sep 2024) | 16 of 16 Mach-O files x86_64 | not signed at all | rejected | no, bad CPU type |
| 9.1.1 x64 zip | x86_64, plus universal SITL | not signed at all | rejected | no, bad CPU type |
| 9.1.1 arm64 zip | arm64, plus universal SITL | ad-hoc, linker-signed | rejected | yes, 512 MB across processes |
| 10.0.0-RC1 arm64 dmg | arm64, plus universal SITL | Developer ID, Thomas Greer (5C7287V86P) | accepted, Notarized Developer ID | yes, 567 MB across processes |
Both Electron builds use Electron 38.7.2 and need macOS 12.0 or later.
"INAV Configurator is damaged and can't be opened"
This is the most common Mac complaint about INAV. Six of the 37 issues are a version of it, from #2245 on the 8.0 RC1 in November 2024 to #2556 on 9.0.0 in February 2026. The files aren't corrupt. Several reporters checked the SHA-256 and it matched. The app is signed ad-hoc and has no sealed resources, so Gatekeeper refuses to open a quarantined copy. Apple's own pre-distribution check says the same thing:
$ codesign -dvv "INAV Configurator.app" # 9.1.1 arm64
CodeDirectory v=20400 size=392 flags=0x20002(adhoc,linker-signed)
Signature=adhoc
TeamIdentifier=not set
Sealed Resources=none
$ syspolicy_check distribution "INAV Configurator.app"
App has failed one or more pre-distribution checks.
Full Error: Code has no resources but signature indicates they must be
present. Please re-sign using the latest version of macOS and codesign.The maintainers' fix is to clear the quarantine flag after copying the app to Applications:
xattr -cr "/Applications/INAV Configurator.app"-c clears every extended attribute it can, and -r recurses into the bundle. When I tagged a copy with com.apple.quarantine and ran it, only com.apple.provenance was left. xattr -dr com.apple.quarantine does the narrower version of the same job. If xattr says the attribute isn't there, the copy was never quarantined, which I covered in "No such xattr: com.apple.quarantine".
Here's the part that keeps sending people to the issue tracker. From 8.0.0-RC1 to 9.0.2, 13 releases in a row carried a bold "Important!!" notice with that command and the line "We currently don't have access to an Apple Developer Account to sign the Mac binaries". The 9.1.0 and 9.1.1 release notes dropped it, but 9.1.1 is still unsigned. Meanwhile the README now says "Official tagged builds (9.1.3 or v9.1.3) are signed and notarized". There is no 9.1.3 release. The newest tag is 9.1.1, and the latest stable build a Mac owner can download today is not signed.
Signing only arrived this autumn. Pull request #2720, merged on 2026-09-17, added optional Developer ID signing and notarization to CI. It also explains why earlier signing attempts would have failed anyway: the build removed SITL binaries for other operating systems after signing, and that broke the signature. 10.0.0-RC1 came out a week later and is the result. spctl accepted it, stapler validated the ticket, and syspolicy_check passed it. The DMG wrapper itself is still unsigned. That doesn't matter for opening the app, because Gatekeeper checks the app inside.
Homebrew won't install it any more
brew install --cask inav-configurator used to be the easy route. The cask still points at 9.1.1, and its arm64 checksum matches the zip I downloaded, but it has been switched off:
$ brew info --cask inav-configurator
==> inav-configurator (INAV Configurator): 9.1.1
Disabled because it does not pass the macOS Gatekeeper check! It was disabled on 2026-09-01.That follows Homebrew's acceptable casks policy, which says Mac apps "must pass Homebrew's Gatekeeper checks and must not require System Integrity Protection or Gatekeeper to be disabled or bypassed". Betaflight's cask is in a different state. It still points at the Intel-only 10.10.0 and is marked deprecated as "discontinued upstream", with a disable date of 2026-12-26 (background in Betaflight on Mac). Once a notarized stable INAV release ships, the cask could come back, but that's Homebrew's call. Until then, download from the GitHub release page.
Testing it without a flight controller: the bundled SITL
Both Electron builds I checked include inav_SITL, a software-in-the-loop build of the firmware that the configurator can start for you. It is a universal binary, the one piece of the x64 build that would also run natively on Apple silicon. I started the arm64 slice from the 9.1.1 bundle by hand and queried it with a 20-line MSP script over TCP:
$ ./inav_SITL
INAV 9.1.0 SITL (50c8ea0c)
[SIM] No interface specified. Configurator only.
[SOCKET] Bind TCP [::]:5760 to UART1
[SOCKET] Bind TCP [::]:5761 to UART2
$ python3 msp.py 5760
API_VERSION 697.89 ms b'\x00\x02\x05'
FC_VARIANT 0.60 ms b'INAV'
FC_VERSION 1.69 ms b'\t\x01\x00'
BOARD_INFO 1.70 ms b'SITL\x00\x00\x02\x00\x04SITL'It answered as INAV 9.1.0 on board "SITL" and settled at about 1.5% CPU. The 9.1.1 app bundles a 9.1.0 SITL, which is fine because 9.1.1 changed only the configurator. The SITL listens on all network interfaces rather than only on localhost, so on a shared network anyone who can reach your Mac can connect to port 5760.
What I couldn't test is the USB side. With no flight controller there's no serial port to open, so I have no first-hand result on flashing or connecting over USB. For which USB-serial chips macOS drives without extra software, see USB to serial adapters on Mac.
What Mac owners still report
Five of the 37 issues are still open. The newest is the most specific. In #2791 (September 2026), the same Matek F405-WMO and the same USB-C cable connect fine from an M1 and an M2 MacBook Air, but on an M4 Pro the serial port opens and then MSP times out after exactly 10 seconds. A project member sent a pre-release 10.0 build. The reporter tested it and got the same timeout. In #2338, 22 comments long and open since February 2025, 8.0.0 on M1 wouldn't start for several people. Some were fixed by xattr -cr on a fresh copy and some weren't. #2457 shows that packaging has gone wrong before. In a 9.0 release candidate the x64 archive contained a Windows .exe, and a commenter found x86_64 code in the arm64 package. Both were fixed for 9.0.0.
The version rule matters more than any of that. Configurator and firmware major versions have to match. The 10.0.0-RC1 notes say it is "for use with INAV 10.x firmware only", and #2325 points out that 8 couldn't manage 7. Every Mac build installs as the same INAV Configurator.app with the same bundle ID, so dragging 10.0 into Applications replaces 9.1.1. If you fly INAV 9 and want to try the notarized RC, rename the old app to INAV Configurator 9.app first. Issue #2325 asks for exactly that naming change and is still open.
Of the three flight tools I've checked this week, INAV is the only one with a notarized arm64 build, and only on its release-candidate line. Betaflight ships arm64 without notarization, and Mission Planner on Mac has no Apple silicon build at all.
FAQ
Is INAV Configurator available for Mac?
Yes. INAV Configurator 9.1.1 has separate macOS downloads for Apple silicon (arm64) and Intel (x64) on its GitHub releases page, both needing macOS 12 or later. The arm64 build runs natively on M-series Macs but is not notarized. Version 10.0.0-RC1 is the first notarized Mac build, and it only works with INAV 10 firmware.
How do I fix "INAV Configurator is damaged and can't be opened" on Mac?
Copy the app to Applications and run xattr -cr "/Applications/INAV Configurator.app" in Terminal, then open it again. The download is not actually damaged. Builds up to 9.1.1 only carry an ad-hoc signature, so Gatekeeper refuses to open a quarantined copy. Removing the quarantine attribute stops that check. The notarized 10.0.0-RC1 build does not need this step.
Can I install INAV Configurator with Homebrew?
Not at the moment. Homebrew disabled the inav-configurator cask on 2026-09-01 because the 9.1.1 app does not pass the macOS Gatekeeper check, so brew install --cask inav-configurator refuses to install it. Download the MacOS_arm64 or MacOS_x64 zip or dmg from the GitHub releases page instead.

How I checked: on 2026-10-23 I downloaded INAV Configurator 7.1.2 (zip), 9.1.1 arm64 and x64 (zip) and 10.0.0-RC1 arm64 (dmg) from GitHub, and inspected them with file, codesign, spctl, stapler and syspolicy_check on a Mac mini M4 running macOS 26.4.1 without Rosetta. I launched the two arm64 apps, but this Mac is headless, so I measured processes and memory rather than looking at the window. The SITL test used the arm64 slice of the bundled inav_SITL and my own MSP v1 script. Download counts are from the GitHub releases API on the same day. The issue count is a title search of the inav-configurator repository for the eight terms listed above, 37 unique issues from 2017 to 2026. I have no INAV flight controller, so USB connection, flashing and flight are not tested here. Statements about them come from the linked GitHub issues.
