# Detect macOS browser

Guess whether the device is a Mac, iPhone or iPad from the platform string.

Canonical: https://1loc.dev/dom/detect-macos-browser/
Version: 1.0.0
Runtime: JavaScript · modern browsers (DOM)
Verification: Usage lines executed in headless Chromium against the fixture markup; no external services
Updated: 2026-10-28

## Implementation

```javascript
function isApplePlatform() { return /Mac|iPhone|iPad|iPod/.test(navigator.userAgentData?.platform ?? navigator.platform); }
```

## Usage

```javascript
// Headless Chromium on Linux:
isApplePlatform(); // → false
isApplePlatform(); // e.g. true on a Mac, an iPhone or an iPad
```

Lines marked → were executed in headless Chromium against the markup above, and each result was compared with the value shown. Lines marked e.g. are illustrative.

## Limits

- navigator.platform is deprecated, and iPadOS reports "MacIntel" in desktop mode, so this cannot tell a Mac from an iPad. Chromium’s navigator.userAgentData is read where available.
- Use it for keyboard hints (⌘ versus Ctrl), not for features: detect those directly.

The function does not validate its arguments. Add checks where it receives untrusted input.
