ViableS
ViableS is a macOS virtualisation app for Apple silicon that runs macOS virtual machines in a sandboxed, more isolated environment.
What is ViableS?
ViableS is a native macOS virtualisation app for running macOS virtual machines on Apple silicon Macs. It is designed for users who want a more locked-down VM workflow, including security research, software testing, and opening potentially risky content in a separate environment. ViableS supports running prepared macOS VMs, works with .vimi bundles, and gives users control over network configuration, including NAT, bridged networking, or no network connection. It also supports Sonoma-era virtual display features such as autoscaling and is intended for Monterey and later. ViableS is published by Howard Oakley as part of his Mac utility lineup and is especially useful when you want VM isolation without sharing folders or clipboards with the host Mac.
Key features
- Run macOS virtual machines on Apple silicon Macs
- Open and use .vimi virtual machine bundles
- Choose NAT, bridged, or disabled network connections for a VM
- Use a sandboxed environment for more isolated testing and research
- Run prepared virtual machines without sharing folders with the host
- Use autoscaling virtual display support on supported macOS versions

Safety overview
Status: Mostly safe
ViableS is a legitimate Mac virtualisation tool intended to isolate guest systems from the host Mac more strictly than a general-purpose VM app. Network access, virtual disk use, and access to VM bundles are normal for this type of software. Because it is often used to open test systems or suspicious files inside a VM, the main precaution is to keep risky activity inside the virtual machine and avoid moving untrusted files back to your main Mac unless you have checked them first.
Recommendation: Keep ViableS if you use macOS virtual machines for testing, research, compatibility checks, or isolated browsing. If you no longer run VMs with it, you can remove the app and any VM bundles you created separately, but doing so will also remove your ability to launch those machines with ViableS.
