A raw High Sierra VMDK feels sluggish. Apply these tweaks:

| Setting | VMware | VirtualBox | | :--- | :--- | :--- | | Graphics | Enable 3D acceleration (set vram to 2GB) | Enable 3D & 2D acceleration, set vram to 256MB | | CPU | 2 sockets, 2 cores each (total 4) | Execution cap: 100%, Paravirtualization: Default | | Disk | Use .vmdk flat (pre-allocated) | Use .vmdk (do not convert to VDI) | | Network | VMXNET3 (for gigabit speeds) | Intel PRO/1000 MT Desktop |

After booting, open Terminal in High Sierra and run:

# Disable spotlight indexing on the VM (huge speed boost)
sudo mdutil -a -i off

  • Parallels Desktop:

  • VirtualBox (on Mac hosts; Intel-based macs only):


  • APFS introduced a feature called "Copy-on-Write." This is a game-changer for virtualization workflows.

    To ensure the VM boots without errors, you often need to edit the configuration file.

    After testing over a dozen sources, the best macOS High Sierra VMDK download balancing speed, safety, and features is:

    Archive.org: “macOS 10.13.6 (17G66) VMware – Prepped with Tools + SIP disabled (optional)”
    File size: 5.8 GB compressed, 19.5 GB expanded.
    SHA256: Check the upload page (varies by mirror).

    Runner-up (for VirtualBox users): Geekrar’s 10.13.6 dual-format image.

    Avoid any VMDK that claims “Works on AMD Ryzen” without a kernel patch – High Sierra does not support AMD CPUs natively in a VM without extensive hacking (and then it’s unstable).


    The single best "download" is not a file at all—it is a process. By spending 90 minutes creating your own VMDK using gibMacOS and VMware Fusion, you get:

    If you absolutely need a pre-built VMDK, the Internet Archive offers the safest, most transparent downloads, but always verify the SHA-256 checksum against known good hashes posted in VMware community forums.

    Remember: There is no "best" shortcut. The best is secure, the best is stable, and the best is legal. Build, don’t steal—and your macOS High Sierra VM will run flawlessly for years to come.
