## What it is
A collection of archived Apple macOS SDK folders (MacOSX10.1.5.sdk through MacOSX11.3.sdk) compiled from various Xcode releases. It lets developers target older macOS versions by pointing SDKROOT at a specific SDK.

## Use cases
- build a mac app that supports older macOS versions
- download an old MacOSX SDK for Xcode
- compile software with MacOSX10.9.sdk on modern Xcode
- cross-compile for older macOS from a newer machine
- fix MinimumSDKVersion errors when using legacy SDKs
- set SDKROOT to an old macOS SDK for a CMake build

## When to choose
- you need to build or cross-compile against an old macOS SDK that Apple no longer ships
- you want to support legacy macOS versions with modern Xcode
- you need a specific SDK version for reproducing or maintaining old builds

## When to avoid
- you only target current macOS versions and can use the SDK bundled with Xcode
- you need official Apple support or licensing for the SDKs
- you need SDKs newer than 11.3

## Facets
- artifact type: dataset
- maturity: maintenance
- function: developer-tools, build-tool
- domain: developer-tools, operating-systems, cross-platform
- platform: cross-platform
- tags: macosx-sdks, xcode, apple-sdks, sdkroot, backward-compatibility, macos
