AI Assistants That Control Your Mac: What They Can Do and How to Use Them Safely

AI assistants are starting to move beyond answering questions. Some can now use your Mac much as you do, opening apps, reading files, navigating websites, changing settings and completing tasks across several applications.

This article is part of our series on using AI at home and at work.

That opens up some genuinely useful possibilities.

Instead of asking an AI how to organise a collection of files, for example, you could ask it to organise them. It could collect information from several places and turn it into a report, work through a repetitive browser task, check an application for a problem, or use software that does not have its own AI integration.

The trade-off is access. An AI that can operate your Mac needs considerably more permission than one sitting in a chat window.

That does not make these tools inherently unsafe. It does mean they are worth setting up thoughtfully.

What an AI assistant can actually do on a Mac

There are several ways an AI assistant can get work done.

The safest and most reliable method is often a direct connection to the service it needs. An assistant might use an approved connector to work with Microsoft 365, Google Drive, Gmail or Slack, for example.

When no suitable connection exists, some assistants can use a browser instead.

Computer control takes this another step. The AI can see what’s happening on screen and interact with applications by clicking, typing and navigating their interfaces.

Anthropic’s computer-use capability in Claude Cowork and Claude Code, for example, can work with apps and files on a Mac. Anthropic says Claude tries more precise tools such as connectors first, then a browser, before interacting directly with the screen where appropriate.

OpenAI offers a similar Computer Use capability through ChatGPT. On a Mac, Screen Recording allows it to see an application and Accessibility allows it to click, type and navigate.

The important distinction is that these assistants aren’t simply telling you what to do. With the right permissions, they can do some of it themselves.

Where this can be genuinely useful

The attraction is easy to understand.

Many computer tasks are not particularly difficult, they’re just tedious. Moving through several applications, collecting information, renaming files or navigating repetitive interfaces can consume considerably more time than the actual thinking involved.

An AI assistant could help with jobs such as:

organising copies of project files into sensible folders
gathering information from several sources for a report
checking information in a browser and another application
working through repetitive administrative tasks
testing a website or application
preparing drafts using information from approved files
operating specialist software that has no direct AI integration

There is also an accessibility benefit. Someone who finds repetitive mouse or keyboard work difficult may eventually find computer-controlling assistants particularly useful.

And these tools should become more capable as developers connect them directly to more services. A direct, tightly controlled connection is generally preferable to having an AI visually hunt around a screen for the right button.

So we don’t think the right response is to avoid this technology.

The better question is: what does the assistant need to see and change to perform the job you’ve given it?

Why the permissions matter

An ordinary chatbot generally knows only what you type, upload or intentionally connect to it.

An assistant controlling your computer can potentially see much more.

It may need to see your screen, access a folder, interact with another application or perform actions on your behalf. If those permissions are broader than necessary, a simple mistake can have a much larger consequence.

There’s also a difference between letting an AI read something and letting it change something.

Reading a document might expose information you did not intend to share. Changing a document introduces an additional risk: the AI may misunderstand the instruction and alter the wrong thing.

The stakes increase further if the action involves sending an email, deleting a file, running a command, publishing something or making a purchase.

Anthropic makes the same distinction between read tools and write tools, and recommends human oversight for higher-stakes actions because Claude can make mistakes.

That is a useful way to think about any AI assistant, regardless of who makes it.

What your Mac lets you control

macOS already has privacy controls that restrict what applications can see and do.

You’ll find them under System Settings > Privacy & Security.

The permissions particularly relevant to AI assistants include:

Files & Folders: access to locations such as your Desktop and Documents folders.
Accessibility: allows approved applications to interact with and control parts of the Mac interface.
Screen & System Audio Recording: allows an application to see what’s happening on your screen.
Automation: allows one application to control another.
App Management: can allow an application to update or delete other applications.
Full Disk Access: provides exceptionally broad access to information on the Mac.

Don’t automatically assume an AI application needs every permission it requests.

If you’re using it to carry out one specific task, give it what that task requires and no more.

Full Disk Access deserves particular care

Full Disk Access is different from allowing an application to use a single folder.

On 2 October 2026, Apple warned that Full Disk Access largely sidesteps the privacy controls normally protecting information on a Mac. Apple said it can expose files, mail, messages and browsing history, and specifically noted that the risks grow as AI agents become increasingly capable and autonomous.

Full Disk Access has legitimate uses. Backup software is an obvious example because it may need to read almost everything in order to protect it.

That doesn’t mean every application should receive the same access.

If an AI assistant asks for Full Disk Access, don’t enable it simply to make a permission warning disappear. Find out which feature needs that access and whether a narrower permission can accomplish the same thing.

For most experiments with AI computer control, we’d start without Full Disk Access.

Some processing may happen away from your Mac

Mac permissions tell you what an application can access. They don’t necessarily tell you where that information is processed afterwards.

That’s an important distinction.

Anthropic says Claude Cowork sessions run in an isolated environment on its servers. When Claude needs a connected local file or browser, it can reach the Mac through the desktop application, with that information processed on Anthropic’s servers rather than remaining entirely on the Mac.

That may be perfectly acceptable for many everyday tasks.

It becomes a more important consideration when you’re dealing with customer information, confidential documents, commercially sensitive material or other people’s personal information.

For business use, don’t look only at whether the Mac displays an Allow button. Check the provider’s data and privacy terms for the plan you’re actually using.

There is another risk called prompt injection

Computer-controlling AI introduces a less obvious problem.

The instructions influencing the assistant may not all come from you.

A webpage, email or document can contain content deliberately designed to influence an AI assistant into taking an unintended action. This is generally known as prompt injection.

AI companies are building protections against it. Anthropic, for example, says its computer-use safeguards include measures intended to detect prompt-injection activity.

But protections are not a reason to abandon normal caution.

An assistant that can read an unfamiliar website and summarise it presents one level of risk. An assistant that can read that website, access your files, send messages and run commands presents another.

The more an assistant can do, the more carefully its access should be limited.

A safe way to try one

You don’t need to hand an assistant the keys to your digital life just to find out whether computer control is useful.

Start with one simple job.

Use a test folder containing copies of files that don’t matter. Give the assistant access to that folder rather than your whole filing system, if the software allows it.

Good first experiments might include organising sample files, comparing two public documents, gathering public information or working through a repetitive task where the result is easy to check.

Keep approval prompts turned on and stay with the assistant for its first few tasks.

This is increasingly important because computer control doesn’t necessarily mean watching your mouse move around. Anthropic says that, on macOS 15 or later, Claude can work in background windows without taking over your pointer or keyboard.

Always check the result yourself.

An AI’s report saying it successfully completed a task is not the same thing as verifying that it did.

A quick check before you give an AI control

Before letting an AI assistant operate your Mac:

Check that you have a current backup.
Open System Settings > Privacy & Security and see what permissions the application already has.
Give it access only to the applications and folders needed for the job.
Avoid Full Disk Access unless you understand exactly why it is required.
Use non-sensitive files for your first experiments.
Keep approval prompts enabled.
Check what the assistant actually changed.
Remove permissions you no longer need when you’ve finished testing.

This doesn’t eliminate every risk, but it substantially limits how much damage a mistake can cause.

Be particularly careful with Terminal commands

An AI assistant may sometimes suggest a Terminal command to install something, change a setting or accomplish something it cannot easily do through the normal Mac interface.

Terminal itself is not dangerous, and it can be an extremely useful Mac tool.

The problem is blindly running a command you don’t understand.

Scammers also use the copy-and-paste-a-command technique because a Terminal command can bypass the reassuring visual interfaces people normally associate with installing software or changing a setting.

If an AI gives you a command, ask it to explain what every part does before running it.

Be especially cautious if the command changes security settings, deletes data, installs software, requests administrator privileges or downloads something from an unfamiliar source.

What about passwords and financial information?

We would keep these outside an AI computer-control experiment.

Don’t deliberately give an assistant access to your password manager, online banking, saved payment cards or authentication codes simply to make a task more convenient.

The same applies to particularly sensitive personal documents.

Convenience needs to be proportional to the job.

Having an assistant rename 200 harmless photographs could save a lot of time with little consequence if it makes a mistake. Giving it unrestricted access to business banking to save a few clicks is a very different proposition.

Families and shared Macs

We wouldn’t enable a Mac-controlling AI assistant in a child’s account at this stage.

These tools can request powerful permissions, open websites and files, and take actions that may be difficult for a child to assess.

On a shared Mac, adults and children should have separate user accounts. Keep browser profiles, personal files and password managers separate as well.

For schoolwork and general questions, a conventional AI chat tool with appropriate family controls is a simpler starting point than an assistant with permission to operate the computer.

Small businesses should treat this as software, not just chat

For a business, the potential benefits become particularly interesting.

An assistant that can move between business systems could eventually take some of the repetitive work out of administration, reporting, document preparation, research and specialist applications that don’t have their own automation.

But once AI can access company files, email and business applications, it needs to be managed accordingly.

Decide which staff are allowed to enable computer control, what information the assistant may access, which permissions are acceptable and which actions always require human approval.

Customer records, staff information, financial systems and confidential business data deserve particular care.

The same principle applies to an assistant as to any other cloud service: understand what data is being shared, where it is processed and which account or business agreement governs it.

If your business already has an AI policy, computer-controlling assistants should be included in it.

The benefits and risks are really the same thing

The interesting thing about this technology is that its greatest advantage is also what creates the risk.

An assistant that can only tell you how to do something can’t accidentally do it.

An assistant that can actually complete the job can save much more time, but it can also make a real-world mistake.

That doesn’t mean computer-controlling AI is a bad idea. It means permissions and oversight matter more as the technology becomes more capable.

The aim should not be to give AI as much access as possible. It should be to give it enough access to do a useful job well.

What we would do

For most people, we wouldn’t start by giving an AI assistant control of the whole Mac.

Ordinary AI chat, a trusted connector or a business AI service such as Microsoft Copilot will cover many everyday jobs without requiring broad access to the computer.

But computer control is becoming much more interesting, and there are already jobs where it can remove genuinely tedious work.

If we wanted to try it, we’d choose one of those jobs first.

We’d use non-sensitive information, give the assistant the smallest set of permissions that allows it to complete the task, keep approval prompts turned on and make sure there is a backup before allowing it to modify anything important.

Then we’d expand its access only when there was a clear benefit in doing so.

The question isn’t simply whether you trust the AI company. It’s what the assistant can see, what it can change, and what happens if it gets something wrong.
