Any Mac running an unpatched macOS release that predates the fixed versions can be affected, since the flaw sits in the operating system itself. The sources do not say which earlier builds are vulnerable or whether any special configuration is needed, so treat all unpatched Macs as in scope. Teams that only run managed, fully patched Macs with current releases can skip the emergency response.
