VM indicating wrong architecture (ARM)


ARM users may notice that commands like arch indicate the VM is i386/intel. Or, system_profiler SPHardwareDataType chip_type will be Unknown:

  "SPHardwareDataType" : [
      "_name" : "hardware_overview",
      "activation_lock_status" : "activation_lock_disabled",
      "boot_rom_version" : "8419.80.7",
      "chip_type" : "Unknown",
      "machine_model" : "VirtualMac2,1",
      "machine_name" : "Mac",
      "model_number" : "VM0001LL/A",
      "number_processors" : 6,
      "os_loader_version" : "8419.80.7",
      "physical_memory" : "14 GB",
      "platform_UUID" : "E465E3CB-0162-5E0E-9CEA-FED57C72BE74",
      "provisioning_UDID" : "E465E3CB-0162-5E0E-9CEA-FED57C72BE74",
      "serial_number" : "ZNNF3941VQ"


This is caused by running an amd64 process or service on the VM. Rosetta will start Translating all other operations through Rosetta. You’ll want to ensure all software installed inside of the VM was built for arm64.
