Looking for a VirtualBox alternative
If you came to VirtualBox on Apple silicon expecting the tool you used on Intel, the gap you felt is real. Whether 1VMTool closes it depends on whether you need cross-platform appliances.
First: do not switch if this is you
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.
1VMTool is an early product. It is deliberately narrower than Oracle VirtualBox, and a narrower tool is only an upgrade when the part it does well is the part you need.
What frustrates people about Oracle VirtualBox
- 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.
What you gain by moving
- 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.
How they actually differ
| 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. |

Moving across
- Keep Oracle VirtualBox installed. There is no importer — machine formats do not transfer — so treat this as running both for a while rather than a migration.
- Recreate one machine you actually use in 1VMTool and work in it for a week. One real machine tells you more than a checklist.
- Take a safe point as soon as it is set up, then deliberately break something and restore it. That loop is the reason to switch; test it early.
- Only then decide. If the loop did not change how you work, the honest answer is to stay on Oracle VirtualBox.
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.
