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
