build: conditionally compile media capture permission for macOS deplo… by JakiChen · Pull Request #1776 · tauri-apps/wry

JakiChen · 2026-07-21T01:50:34Z

Motivation

When building wry with a macOS deployment target lower than 12.0 (e.g. 10.15 or 11.0), compilation fails because the delegate method requestMediaCapturePermissionForOrigin:initiatedByFrame:type:decisionHandler: is only available on macOS 12.0+. This forces downstream users to maintain forks or manually patch wry.

Solution

In build.rs, read the MACOSX_DEPLOYMENT_TARGET environment variable and set custom cfg flags macos_12_or_later / macos_11_or_earlier.
Guard the entire requestMediaCapturePermissionForOrigin method with #[cfg(macos_12_or_later)].
On older deployment targets the method is excluded, so the system default permission flow takes over (no functional loss).

The recently added custom permission_handler logic is fully preserved when compiling for macOS ≥ 12.

Testing

Built a Tauri 2 project using this branch with MACOSX_DEPLOYMENT_TARGET=11.0: compilation succeeds (previously failed).
Built with MACOSX_DEPLOYMENT_TARGET=12.0: compilation succeeds and the permission handler works as expected.

Impact

No behavioral change for macOS 12+ builds.
Removes the need for downstream patches when targeting older macOS versions.

do you have an error log or something for the compilation failure?

JakiChen · 2026-07-21T08:13:47Z

@FabianLars Thanks for the review.

Below is the full error log for this patch not being applied. This log was compiled on my macOS 11.7.11 system, MACOSX_DEPLOYMENT_TARGET=11.0 (this issue should not occur on newer versions of macOS):

thread caused non-unwinding panic. aborting.

Additionally, I've verified the fix locally by applying this patch to my Cargo.toml:

[patch.crates-io]
wry = { path = "../wry" }  # Points to my local branch with this PR changes

With this patch, the project compiles successfully under the same deployment target.

Regarding the fix itself: I'm fully open to alternative implementations. If you think there's a cleaner or more comprehensive solution (e.g., adjusting the cfg attributes, using a different type, or even a different approach to maintain backward compatibility), I'd be happy to update this PR or close it in favor of your preferred approach. My main goal is to ensure that users on older macOS versions can compile wry without trouble.

FabianLars · 2026-07-21T08:34:55Z

alright thanks. so it's another case of madsmtm/objc2#645 :/

Can you check if this happens in release as well? (tauri build or tauri dev --release)
If so then we can put this behind a debug_assertion check because this approach would really suck for production apps (though i can't think of a better one right now either)

JakiChen · 2026-07-21T11:36:40Z

@FabianLars I think we're on the same page about the root cause (objc2#645), but I'd like to clarify why I believe the deployment-target-based conditional compilation is the right long-term fix.

The Problem

The panic occurs because requestMediaCapturePermissionForOrigin doesn't exist on macOS < 12.0. This is not a runtime issue — it's a compile-time issue because objc2 tries to generate a method override for a protocol method that doesn't exist on older SDKs.

Why `debug_assertions` is a temporary workaround, not a fix

Scenario	`debug_assertions` approach	My PR (based on `MACOSX_DEPLOYMENT_TARGET`)
`tauri dev` (Debug)	✅ Works (skips the method)	✅ Works
`tauri build --release` (Release)	❌ Panic on macOS 11 (method still compiled)	✅ No panic (method excluded based on deployment target)
User configurable	❌ No — hardcoded to build mode	✅ Yes — via `minimumSystemVersion` in `tauri.conf.json`
Supports multiple distributions	❌ Can't produce a macOS 11-compatible release build	✅ Yes — set `minimumSystemVersion: "11.0"` and get a working app

The User Experience After This PR

Developer sets minimumSystemVersion: "11.0" in tauri.conf.json.
Tauri passes MACOSX_DEPLOYMENT_TARGET=11.0 to wry.
wry's build.rs reads it and sets #[cfg(macos_11_or_earlier)].
The requestMediaCapturePermissionForOrigin method is excluded from the binary.
On macOS 11, WebKit uses system default permission handling — no crash, getUserMedia still works.
The developer can also choose to publish a macOS 12+ version with full custom permission UI by setting minimumSystemVersion: "12.0".

One Question for You

Do you think we should also provide a runtime fallback (e.g., checking NSAppKitVersion at runtime) instead of compile-time? That would allow a single binary to work on both macOS 11 and 12+, but it would still require conditionally excluding the method at compile time (since the method doesn't exist on macOS 11). So the #[cfg] is unavoidable.

My Test Results (for reference)

On my macOS 11.7.11 system (where MACOSX_DEPLOYMENT_TARGET defaults to 10.13):

Command	Result	Note
`pnpm tauri dev`	❌ Panic	`objc2` assertion fails
`pnpm tauri build`	✅ Passes	Release mode disables the assertion
`pnpm tauri dev --release`	✅ Passes	But very slow for daily development (minutes per Rust change)

So currently, developers targeting older macOS are forced to use --release mode just to avoid the panic — which hurts development velocity significantly.

I believe this PR is a practical solution to restore normal development experience for users on older macOS, while keeping production builds functional.

Please let me know if you need any additional information (logs, more test results, etc.) — I'm happy to provide whatever helps move this forward. 🙏

FabianLars · 2026-07-21T11:49:03Z

So the thing here is: the way you implemented it, it is also applied to release builds which means if you build an app on macos 11, endusers on 12+ will not have this method working.
There should be no reason to do this though, the panic should be only from objc2's internal checks (that only happen in debug mode), macOS itself should not care if you register delegate methods that it doesn't know about.

So ideally, if you build the release app on 11, register the delegate method, when running the app it should be ignored on 11, and actually do what it's supposed to on 12+.

JakiChen · 2026-07-21T16:23:59Z

@FabianLars , I also realized there was a logical problem in the submitted PR code; the default value should be 12 to better reflect the intended value.

  println!("cargo::rustc-check-cfg=cfg(macos_12_or_later)");
  println!("cargo::rustc-check-cfg=cfg(macos_11_or_earlier)");

  let deployment_target =
    std::env::var("MACOSX_DEPLOYMENT_TARGET").unwrap_or_else(|_| "12".to_string());
  let major: u32 = deployment_target
    .split('.')
    .next()
    .unwrap_or("10")
    .parse()
    .unwrap_or(12);

  if major >= 12 {
    println!("cargo:rustc-cfg=macos_12_or_later");
  } else {
    println!("cargo:rustc-cfg=macos_11_or_earlier");
  }

The script below reads bundle.macOS.minimumSystemVersion from tauri.conf.json and sets MACOSX_DEPLOYMENT_TARGET exactly to that value (no hardcoded mapping).
It also includes an optional --clean flag to force a rebuild of wry when switching targets.

Script (`tauri-env.sh`)

#!/bin/bash
set -e

MODE="${1:-dev}"
SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)"

# Locate tauri.conf.json
CONF_FILE="$SCRIPT_DIR/src-tauri/tauri.conf.json"
[ -f "$CONF_FILE" ] || CONF_FILE="$SCRIPT_DIR/tauri.conf.json"
if [ ! -f "$CONF_FILE" ]; then
  echo "❌ tauri.conf.json not found. Run from project root or src-tauri directory."
  exit 1
fi

# Read minimumSystemVersion
MIN_VER=$(node -e "
  const fs = require('fs');
  const conf = JSON.parse(fs.readFileSync('$CONF_FILE', 'utf8'));
  const ver = conf?.bundle?.macOS?.minimumSystemVersion || '10.13';
  console.log(ver);
")

echo "📋 minimumSystemVersion from tauri.conf.json = $MIN_VER"
export MACOSX_DEPLOYMENT_TARGET="$MIN_VER"

# Optional clean
if [[ "$*" == *--clean* ]]; then
  echo "🧹 Cleaning wry cache..."
  (cd "$(dirname "$CONF_FILE")" && cargo clean -p wry 2>/dev/null || true)
fi

cd "$(dirname "$CONF_FILE")"

if [ "$MODE" = "build" ]; then
  echo "🚀 Starting Tauri build..."
  pnpm tauri build
else
  echo "🚀 Starting Tauri dev server..."
  pnpm tauri dev
fi

How to build for different macOS versions

Set the desired deployment target in tauri.conf.json:

"bundle": {
  "macOS": {
    "minimumSystemVersion": "11.0"   // or "10.13", "12.0", etc.
  }
}

Run the script (it will pick up the value automatically):

chmod +x tauri-env.sh
./tauri-env.sh              # dev mode
./tauri-env.sh build        # production build
./tauri-env.sh --clean      # force wry rebuild when switching

The above ideas are for reference only, and I am not certain about them.

This is my first attempt to quickly validate a product prototype using Tauri. I feel exhausted from investing so much time and energy in it. (Perhaps patching and script control is currently the optimal solution for me.) However, local builds take up too much disk space. And I can't synchronize with the latest Wry from the official website (which is a real shame).

JakiChen · 2026-07-22T00:59:10Z

Heyyyyyy, @FabianLars

I realized my previous script had a bug — cargo clean -p wry must run before export MACOSX_DEPLOYMENT_TARGET, otherwise wry won't recompile with the new target.

This updated version reads minimumSystemVersion from tauri.conf.json, maps it to the desired deployment target (10.13 → 10.13, ≥12 → 12.0, otherwise 11.0), cleans wry cache, and then exports the variable for pnpm tauri dev/build.

It solves the need to build different macOS versions without manual setup.

#!/bin/bash
set -e

# Usage instructions
usage() {
  cat <<EOF
Usage: $0 <MODE>

Automatically reads the macOS minimum system version from tauri.conf.json,
cleans wry cache to ensure the deployment target takes effect, sets
MACOSX_DEPLOYMENT_TARGET accordingly, and runs the Tauri command.

  build      Build the application

  ./tauri-env.sh build

  exit 0

i don't have a macos 11 machine available rn (and can't make the vm working anymore for some reason), can you test this branch? https://github.com/tauri-apps/wry/tree/macos-availability
Requires rust/cargo 1.93 or newer

JakiChen · 2026-07-22T14:35:56Z

The branch builds and all tests pass on my end (macOS 11.7.11). I noticed the source has availability checks gating for macOS 12(#[cfg(not(macos_12_unavailable))]) — looks good.

Heyyyyy @FabianLars , I have a question about the build.rs logic in this #1781 .

It uses operating_system_version() to set macos_12_unavailable, but only when CARGO_CFG_DEBUG_ASSERTIONS is present. In release builds, that cfg is never set, so the new API method is always included.

Doesn’t this mean we cannot produce a release binary compatible with macOS <12 from a newer CI host (e.g., macOS 14) by simply setting MACOSX_DEPLOYMENT_TARGET? Is that the intended behavior?

Just wondering if this has been considered. Thanks.

FabianLars · 2026-07-22T15:19:28Z

This is what I was trying to explain in previous comments. The error you're getting should only happen in debug mode because it's a debug_assertion gated test inside the objc2 crate.

This isn't actually macOS itself complaining about it.

Once we update objc2 to 0.7 (not yet released) we can remove this cfg code here because objc2 will drop the check or at least change it in a way that doesn't crash like it does now.

JakiChen · 2026-07-22T21:24:58Z

@FabianLars

Thanks for the clarification — that really helped. Now I understand that the crash was only a debug assertion inside objc2, not macOS itself blocking anything. That makes sense.

Still, my main worry is about release binaries. If the newer API code is always compiled in when debug_assertions is off, could that lead to subtle compatibility issues down the road, even with MACOSX_DEPLOYMENT_TARGET set? My (possibly naive) expectation was that code paths not valid for the target OS version should ideally be excluded from the final binary to keep things clean and avoid future bugs.

I tried a quick local patch in build.rs that reads MACOSX_DEPLOYMENT_TARGET and sets a cfg like macos_12_or_later or macos_11_or_earlier accordingly, using that to conditionally compile the relevant code. Right now I default to 10.15 if the env var is not set, but that feels a bit arbitrary — maybe it should default to 12.0? I’m not sure about the right default, and I’m also not 100% certain my understanding of how Rust’s conditional compilation and linkage interacts with macOS deployment targets is correct. I’d really appreciate your thoughts on whether this approach makes sense.

And a more general question: would it be possible (or planned) to have the build script read minimumSystemVersion directly from tauri.conf.json and use that to drive the conditional compilation? That feels like the cleanest approach from a user’s perspective — a single source of truth that Tauri already knows about.

I hope you don’t mind these beginner questions — I’m very new to Rust and the ecosystem, and I realize there’s a lot I still need to learn. If I’m missing something fundamental or making incorrect assumptions, I truly apologize. Thanks again for your time and patience!

If the newer API code is always compiled in when debug_assertions is off, could that lead to subtle compatibility issues down the road, even with MACOSX_DEPLOYMENT_TARGET set? My (possibly naive) expectation was that code paths not valid for the target OS version should ideally be excluded from the final binary to keep things clean and avoid future bugs.

Not in this case. Basically there are 2 different kinds of method availability we have to care about on macOS:

First, "normal" methods that we actively call, for example https://github.com/tauri-apps/wry/blob/dev/src/wkwebview/mod.rs#L382C1-L388C8
Here we want to call setElementFullscreenEnabled on WKPreferences but that method was added in macOS 12.3 so we must guard it with version checks that run at runtime on the user's system, since we want to call them on macOS 12.3+ systems but not on older macOS versions. The functionality is also not important enough to raise the Deployment Target to 12.3 (and hence making anybody with older versions unable to run your app).

Secondly, "delegate" methods that we define but are called from "outside", e.g. by macOS or other programs or other part of the same program.
When overwriting a Delegate like we do here, we can even add methods macOS never knew and will never know about and that's okay.
Let's maybe compare that with a REST API. You have an app that calls into some remote REST API. You haven't updated your app in a while but the REST API added new endpoints. Your app keeps working even though it doesn't know about the new endpoints.
The REST API represents our Delegate here and "your app" is macOS / WKWebView using the Delegate.
Now why the crash in Wry? Imagine you're working on the REST API now and want to add a new endpoint without touching the other endpoints. Now your development environment has a development-only check against your production OpenAPI/Swagger that of course doesn't know about the new endpoint yet. -> You see a warning/error in dev, but adding new endpoint to the server is actually okay.

I hope this makes even a little bit of sense, i'm not the best at explaining things, especially this stuff here as it leans heavily to the objc / ffi side instead of being a real rust question. Feel free to ask follow up questions :)

I tried a quick local patch in build.rs that reads MACOSX_DEPLOYMENT_TARGET and sets a cfg like macos_12_or_later or macos_11_or_earlier accordingly, using that to conditionally compile the relevant code. Right now I default to 10.15 if the env var is not set, but that feels a bit arbitrary — maybe it should default to 12.0? I’m not sure about the right default, and I’m also not 100% certain my understanding of how Rust’s conditional compilation and linkage interacts with macOS deployment targets is correct. I’d really appreciate your thoughts on whether this approach makes sense.

I'd say the right default is very subjective. In Tauri we use 10.13 because of technical limitations. We must use some APIs that were added in 10.13 so we can't go lower than that, but as library authors we want the minimum supported OS version as low as possible to give app developers the choice what to support. And for library authors it then also makes sense to set the default deployment target to the minimum version as well.
But if you say hey, i don't care about those 3 users still on macOS 11 or below, or you need APIs that were added in version 12, then you can go ahead and raise it to 12. (12 being an example here)

And a more general question: would it be possible (or planned) to have the build script read minimumSystemVersion directly from tauri.conf.json and use that to drive the conditional compilation? That feels like the cleanest approach from a user’s perspective — a single source of truth that Tauri already knows about.

In Wry? Probablyyy not, it isn't connected to Tauri close enough for that. Ignoring this PR we also have no real reason to check for the deployment target in Wry.
In Tauri we read the deployment target in multiple places, but had to disable it in tauri dev specifically as it caused recompilation issues. ref tauri-apps/tauri#14083 / tauri-apps/tauri#11577
