# Apple OS to WebKit release mapping

## Read this first

This is the lookup table for DuckDuckGo's supported range: **macOS 12.3+** and **iOS 15.0+**. It includes every stable minor and patch release recorded by AppleDB through **2026-10-06**.

Missing version numbers are intentional: Apple did not publish a stable release with that number.

Evidence labels:

| Label | Meaning |
|---|---|
| `exact/tag` | Apple published an OS-specific WebKit source tag. The full five-part source version is known. |
| `exact/binary` | The OS build, WebKit UUID and `CFBundleVersion` were matched in Ravel. |
| `train` | The Safari/WebKit release family is known, but Apple has not published an exact OS-specific source tag. `.*` is intentional. |

An OS marketing version alone is not enough for crash forensics. Hardware-specific OS builds can differ, and macOS can receive Safari/WebKit updates separately. For an exact answer, match **OS build + WebKit UUID + `CFBundleVersion`**.

## iOS mapping

iOS production bundle versions use prefix `8`: `CFBundleVersion = 8 + FULL_VERSION`.

## Binary mappings verified in Ravel

These rows are stronger than a release-name match because the OS build and Mach-O UUID are both known.

### macOS

| macOS | Build | WebKit UUID | `CFBundleVersion` | `FULL_VERSION` |
|---|---|---|---:|---:|
| `26.5.2` | `25F84` | `49B21D99-8716-31B8-8686-71B287325F1D` | `21624.2.5.11.8` | `624.2.5.11.8` |

### iOS

Ravel exposes the binary UUID for these iOS dyld caches, but not the framework `Info.plist`. The `CFBundleVersion` must be captured at runtime before the source mapping can be called exact.

| iOS | Build | WebKit UUID |
|---|---|---|
| `26.6` | `23G71` | `7627FDAB-129E-32BB-A2AC-F0DC02853D4E` |
| `26.6.1` | `23G83` | `C39BD22C-3475-38AF-91BD-0B7574081011` |
| `26.6.2` | `23G90` | `C39BD22C-3475-38AF-91BD-0B7574081011` |
| `27.0.1` | `24A446` | `D12A79A6-98CB-323C-8F72-613AD0983BBC` |

## Current 27.2 beta builds

| Platform | OS build | WebKit UUID | `FULL_VERSION` | Evidence |
|---|---|---|---:|---|
| macOS 27.2 beta | `26B5086k` | `6F6AB57E-1492-3950-9962-85B6AFD430A3` | `625.2.4.1` | Ravel binary |

## Exact lookup procedure

1. Read the OS build and WebKit image UUID from the crash report.
2. Open that build in Ravel and verify the same UUID and architecture.
3. Read `CFBundleVersion` from `Bundle(for: WKWebView.self)`.
4. Remove the platform prefix to obtain `FULL_VERSION`.
5. Resolve the source tag and inspect the released code.

```swift
import WebKit

let webKitBundleVersion = Bundle(for: WKWebView.self)
    .object(forInfoDictionaryKey: "CFBundleVersion") as? String
```

Ravel paths:

```text
macOS: /System/Library/Frameworks/WebKit.framework/Versions/A/WebKit
iOS:   /System/Library/Frameworks/WebKit.framework/WebKit
```

Modern source tags use `WebKit-7<FULL_VERSION>`. The 612 and early 613 trains use `Safari-<FULL_VERSION>`.

## Current certificate-info crash

| Field | Value |
|---|---|
| macOS | `27.0.1 (26A434)` |
| Crash/Ravel UUID | `70BEE322-37EE-3B22-8012-4F76BA105C29` |
| `CFBundleVersion` | `22625.1.29.11.28` |
| `FULL_VERSION` | `625.1.29.11.28` |
| Candidate source tag | `WebKit-7625.1.29.11.28` — not public as of 2026-10-06 |
| Result | The shipped binary has the old one-argument `commitCertificateInfo` ABI; the fix is absent. |

The fix landed in `318982@main`. macOS 27.2 is a candidate for the first fixed system release, but public `WebKit-7625.2.*` source tags are not available yet.
