+## API
+
+### macosVersion()
+
+Returns the macOS version.
+
+### macosVersion.is(semverRange)
+
+Returns a `boolean` of whether the specified [semver range](https://github.com/npm/node-semver#ranges) matches the macOS version.
+
+### macosVersion.isGreaterThanOrEqualTo(version)
+
+Returns a `boolean` of whether the macOS version is greater than or equal to the specified version.
+
+### macosVersion.assert(semverRange)
+
+Throws an error if the specified [semver range](https://github.com/npm/node-semver#ranges) does not match the macOS version.
+
+### macosVersion.assertGreaterThanOrEqualTo(version)
+
+Throws an error if the macOS version is not greater than or equal to the specified version.
+
+*Prefer this over `.assert()` whenever possible as it outputs a more user-friendly error message.*
