1VMTool vs Parallels Desktop
Parallels is the mature commercial answer to running Windows on a Mac. 1VMTool is a younger, narrower app built around making a virtual machine cheap to throw away. They overlap less than the category suggests.
Side by side
| 1VMTool | Parallels Desktop | |
|---|---|---|
| Snapshot mechanism | APFS clone of the disk bundle. Take and restore in well under a millisecond, independent of disk size. | Conventional snapshots plus linked clones on Pro. Seconds-class. |
| Windows on ARM | Experimental first-party engine with a Metal console. No DirectX. | Production quality, Microsoft-authorised, DirectX 11 and OpenGL 4.1, Coherence. |
| macOS guests | Supported on Virtualization.framework. | Supported. |
| Command line | 1vm is a peer of the GUI at every tier. | prlctl is capable but Pro and above only. |
| Pricing model | One-time purchase. | Subscription, or a perpetual license good for one major version. |
| Maturity | Early. Fewer guests, gaps stated on each card. | Two decades of releases and a large support organization. |
| Bundled dependencies | None. Empty package graph. | Own hypervisor, no QEMU. |
| Accelerated 3D | Not shipped. Linux desktops are software-rendered. | DirectX 11 and OpenGL for Windows guests. |

When you should stay on Parallels Desktop
You live inside Windows applications on a Mac — Office with Excel-specific behavior, Adobe, a USB dongle, or anything that needs DirectX. Parallels is purpose-built for that job and 1VMTool is not trying to replace it on those terms. If Coherence is why you bought a Mac VM, stay.
Where Parallels Desktop frustrates people
- Price and the push toward subscriptions. The perpetual Standard license rose sharply with the recent edition, and Pro and Business are subscription-only.
- The command line is gated. prlctl and prlsrvctl are Pro, Business and Enterprise features, so Standard users have no first-class automation story.
- Standard caps the machine at 8 GB of memory and 4 vCPUs, which pushes developers onto a higher tier for reasons unrelated to features.
- Snapshots are conventional VM snapshots rather than filesystem clones, and recent releases have shipped repeated fixes for slow snapshot switching and deletion on Apple silicon.
Why someone moves to 1VMTool
- You reset machines constantly and want that to be effectively free rather than a progress bar.
- You want the CLI without paying for a higher tier — every 1VMTool action is available from 1vm.
- You would rather not run a subscription for something you open a few times a month.
- You want an app with no bundled hypervisor or third-party runtime to keep current.
Frequently asked questions
Is 1VMTool a Parallels alternative for running Windows apps?
Not today. If the job is Windows Excel, Adobe or a USB dongle sitting next to your Mac apps, stay on Parallels. 1VMTool's Windows support runs on its own engine, is labeled experimental, and does not claim DirectX.
Does Parallels have a command line?
Yes, prlctl, and it is good. It is only included in the Pro, Business and Enterprise tiers. 1VMTool ships its CLI to everyone.
Can Parallels snapshot as cheaply as 1VMTool?
No. Parallels snapshots are a real feature but they are conventional VM snapshots, not filesystem clones, so their cost scales with the disk. 1VMTool clones the disk bundle with APFS and restores in a fraction of a millisecond.
