I've been using mvn-jlink-wrapper on my machine with the following config

<provider>ADOPTIUM</provider>
<providerConfig>
    <repositoryName>temurin21-binaries</repositoryName>
    <version>21U</version>
    <arch>x64</arch>
    <type>jdk</type>
    <impl>hotspot</impl>
    <build>2024-01-14-11-20</build>
</providerConfig>

Unfortunately, on my Mac this fails unless I specifically put the <os>mac</os> configuration.
Instead the wrapper tries to download the unix binary.
This is caused by the following code:

public static HostOs findHostOs() {
  return VALUES.stream().filter(x -> x != UNKNOWN).filter(HostOs::isHostOs).findFirst()
      .orElse(UNKNOWN);
}

The resulting HostOs will be UNIX because org.apache.commons.lang3.SystemUtils.IS_OS_UNIX delegates to IS_OS_MAC_OSX.

Furthermore, even if it would detect the right OS, the id needs to be mac and not macos or macosx for the Adoptium provider.
