Mount Thor says it has raised $45 million across seed and Series A financings to expand cloud infrastructure built on Apple hardware.

## The big change

- Mount Thor says it has deployed its first data center and plans to expand its computing footprint. Its funding announcement describes a service and an expansion plan; it does not establish the scale or performance of customer deployments.
- The company offers dedicated Macs and macOS virtual machines. Its documentation says access requests are reviewed, so a public sign-up page is not a promise that everyone can immediately launch a machine.
- A Mac environment can matter when an agent must interact with macOS applications. Buyers should evaluate task completion separately from hosting access, privacy and cost.

## Why an agent needs a computer

A computer-use agent works through a graphical interface: it can observe a screen and choose actions such as clicking, dragging or typing. The independent [MacArena research preprint](https://arxiv.org/html/2606.06560) provides a concrete example of how such systems can be evaluated. Its benchmark runs tasks in macOS virtual machines on Apple silicon, then checks the resulting environment state against the requested goal.

The researchers assembled 421 human-verified tasks spanning 50 applications, including both adapted and new macOS-specific tasks. Their evaluated agents received screenshots and had a 15-step limit per task, with two runs per model. The paper reports difficulty on multi-application tasks and notes that it does not yet include a human performance study. It did not evaluate Mount Thor’s service, and its results are not a claim about Mount Thor customers.

That distinction matters when choosing infrastructure. A researcher testing an agent on a Mac-specific application needs an environment in which that application can run; a screenshot alone cannot show whether a sequence of clicks actually changed the file or setting. A separate evaluation method is needed to decide if the task was completed.

## What Mount Thor offers

According to its November 12 [funding announcement](https://finance.yahoo.com/technology/ai/articles/mount-thor-raises-45-million-140000912.html), CRV and Conviction co-led the Series A, while Chad Byers and Offline Ventures co-led the seed. Mount Thor also says it raised non-dilutive capital for hardware purchases, without specifying an amount. It plans to expand its compute footprint and team; it does not identify customers in the announcement.

The company’s [compute documentation](https://docs.mountthor.com/compute/offerings) distinguishes a dedicated physical Mac from an isolated macOS virtual machine. It says Mount Thor-managed machines are prepared, monitored and wiped by the provider, while organizations can separately manage their own Macs at a Mount Thor site. These are documented terms, not independently tested guarantees.

Researchers can choose an environment, connect to its desktop and run evaluations remotely. The [quickstart](https://docs.mountthor.com/quickstart) requires billing information and a prepaid balance before machine allocation. It also says releasing a managed bare-metal Mac wipes it, while deleting a virtual machine removes its disk. A team should save anything it needs before taking either action.

## Questions before moving work

Mount Thor’s offerings documentation describes charges per managed Mac in 24-hour windows and contract terms for customer-managed Macs. It does not state a public price for each configuration on that page.

Before putting sensitive information or an Apple account into a remote environment, customers should establish the applicable retention, access controls, locations and contract terms. BIG CHANGE did not create an account or test the service.
