====== UTM (macOS Apple Silicon) ======

!!Note: AstLinux 1.5.10 or later is recommended!!

**VM Host Specifications:**  [[https://mac.getutm.app/|UTM macOS]] 

**AstLinux Board Type:**

  * "genx86_64-vm" (VGA video console)

**VM Guest Recommended Options:**

  * Memory: 1024 MB
  * CPU: QEMU Virtual CPU version 2.5+ (qemu64-v1)
  * CPU Cores: 2 Processor Cores
  * Virtual Storage: 4 to 8 GB
  * Network: Bridged (Advanced)
  * Emulated Network Card: virtio-net-pci

**Configuration:**

AstLinux now runs fine (though a bit slower) as an emulated x86_64 guest VM in UTM on Apple Silicon Macs (M1 and newer).

As tested, AstLinux 1.5.10 VM ISO, using UTM 4.6 on macOS 14.7.4, M2 Mac Mini.

  Start Custom -> Emulate -> Custom Other

As typical, the genx86_64-vm.iso installer needs UEFI unchecked to install, but UEFI can be later enabled if desired.

  QEMU -> Tweaks -> UEFI Boot

Cool for testing, the Drive **[1]** and be IDE/SCSI (/dev/sda), VirtIO (/dev/vda) or NVMe (/dev/nvme0n1) supported in AstLinux. Changeable at any time.

Optional, ''ALERT_SOUNDS'' works with:

  Sound -> Emulated Audio Card: PC Speaker

''/mnt/kd/rc.conf.d/user.conf''

  ALERT_SOUNDS="startup shutdown"  # Optional Sounds
  ALERT_SOUNDS_OCTAVE="0"
  
!!Note:!! May only work with the "Internal Mac speaker".

The 'pi' performance test **[2]** takes 31 seconds, about twice as fast as the PC Engines APU2.  Possibly macOS 15 offers additional emulation improvements.
