1VMTool vs Oracle VirtualBox
VirtualBox finally runs on Apple silicon, which makes this comparison worth having. It is free and cross-platform; it is also the newest arrival on this hardware and it shows.
Side by side
| 1VMTool | Oracle VirtualBox | |
|---|---|---|
| Snapshot mechanism | APFS clone of the disk bundle. Take and restore in well under a millisecond, independent of disk size. | Conventional snapshots; ARM saved state broke across the 7.1 to 7.2 upgrade. |
| Price | One-time purchase. | Free base package; Extension Pack is paid for commercial use. |
| Apple-silicon maturity | Built for Apple silicon from the start. | Supported from 7.2 and still receiving frequent ARM fixes. |
| macOS guests | Supported. | Not available on Apple silicon. |
| Command line | 1vm covers every GUI action. | VBoxManage is battle-tested and exhaustive. |
| Cross-platform | macOS only. | macOS, Windows, Linux and Solaris hosts. |
| Open source | Closed source. | GPLv3 base package. |
| Intel Mac support | None. | Yes. |

When you should stay on Oracle VirtualBox
You already script VBoxManage, you share appliances with colleagues on Linux and Windows hosts, or you need a cross-platform lab that behaves the same everywhere. It also still supports Intel Macs, which 1VMTool never will.
Where Oracle VirtualBox frustrates people
- Apple-silicon support is recent and still settling. The 7.2 point releases are still full of ARM and macOS fixes — 7.2.14 repaired ARM guests under 1 GiB of memory and USB on headless macOS 26.4, and 7.2.16 shipped in August 2026.
- The Extension Pack license split catches people out. USB 2 and 3, NVMe, PXE boot, disk encryption and VRDP all sit behind it, and commercial use is not free.
- Snapshots are conventional VirtualBox snapshots with a progress bar, and ARM saved state from 7.1 was not readable by 7.2.
- No macOS guests on Apple silicon, so it cannot be part of a Mac testing workflow.
Why someone moves to 1VMTool
- Snapshot and restore stop being an operation you wait for.
- You want a Mac-native app rather than a cross-platform one with a Mac port.
- You want macOS guests, which VirtualBox does not offer on Apple silicon.
- You would rather not think about which features live behind a separately licensed pack.
Frequently asked questions
Does VirtualBox work on M-series Macs now?
Yes, from version 7.2, with ARM guests only. Expect more sharp edges than the x86 VirtualBox you remember — the point releases since have been mostly ARM and macOS fixes.
Can I use VirtualBox at work for free?
The base package yes, it is GPLv3. The Extension Pack is not free for commercial use, and that is where USB 2 and 3, NVMe, disk encryption and VRDP live.
Is VirtualBox good for throwaway Linux machines?
The CLI is fine for it, but snapshot and restore will not feel like 1VMTool, and there are no macOS guests. If disposability is the goal, the snapshot mechanism is the thing to compare.
