Text selectable prop is ignored on macOS with Fabric (New Architecture)

[kessenma]

Environment

• react-native -v: 20.0.0 (CLI), react-native 0.81.6
• npm ls react-native-macos: react-native-macos@0.81.3
• node -v: v20.18.2
• npm -v: 10.8.2
• xcodebuild -version: Xcode 26.3, Build version 17C529

Steps to reproduce the bug

1. Create a React Native macOS app using react-native-macos 0.81.3 with Fabric enabled (default in RN 0.81)
2. Add a <Text selectable>Hello World</Text> component
3. Build and run on macOS
4. Try to click and drag to select the text

Expected Behavior

Text should be selectable and copyable when selectable={true} is set, matching the behavior on iOS and the old architecture on macOS.

Actual Behavior

The selectable prop is completely ignored. Text cannot be selected or copied.

Root Cause

In React/Fabric/Mounting/ComponentViews/Text/RCTParagraphComponentView.mm, the isSelectable handling is wrapped in #if !TARGET_OS_OSX, which means on macOS the selectable prop is skipped entirely:

// Line 123-131 of RCTParagraphComponentView.mm
if (newParagraphProps.isSelectable != oldParagraphProps.isSelectable) {
#if !TARGET_OS_OSX // [macOS]
    if (newParagraphProps.isSelectable) {
      [self enableContextMenu];
    } else {
      [self disableContextMenu];
    }
#endif // [macOS]
  }

The old architecture (RCTTextView.mm) does handle this correctly on macOS:

// RCTTextView.mm - old architecture, works correctly
#else // [macOS
  _textView.selectable = _selectable;
  if (_selectable) {
    [self setFocusable:YES];
  }
#endif // macOS]

The Fabric component view needs equivalent macOS selection support — setting _textView.selectable and enabling focus, similar to what the old architecture does.

Reproducible Demo

Minimal reproduction:

import React from 'react';
import { View, Text } from 'react-native';

export default function App() {
  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text selectable>Try to select this text on macOS with Fabric enabled</Text>
    </View>
  );
}

Additional context

• The selectable prop works correctly on the old architecture (non-Fabric) on macOS
• The userSelect: 'text' style also does not work as a workaround
• RCTParagraphComponentView.mm also references isSelectable for canPerformAction: (copy:) and acceptsFirstResponder, but the actual selection enabling in updateProps is gated behind !TARGET_OS_OSX
• This affects react-native-macos 0.81.3 with the New Architecture enabled (default in RN 0.81)
