Perplexity’s AI Agent Can Now Run Entirely on Your Mac, but It Needs 36GB of Memory

What did Perplexity launch for Apple silicon Macs?

Perplexity Computer can now run its AI model, orchestration harness, and task execution entirely on supported Apple silicon Macs. Perplexity announced the local capability on October 20, 2026, describing it as an option that keeps the core agent workflow on the Mac rather than sending personal data to a remote service by default. Perplexity’s announcement confirms that the feature is available through the company’s Mac app.

Perplexity Computer is an agent-style system, meaning the software is intended to carry out tasks rather than only produce a text response. The orchestration harness is the component that coordinates the model, task sequence, and tools used during that work. Running those components locally matters because documents, notes, and app activity can remain on the user’s Mac when local processing is selected.

The local rollout does not mean every Computer request remains offline. Perplexity still lets users approve cloud processing for tasks that require current web information, browser access, connected apps, or stronger reasoning. The practical benefit is control: users can keep a private task local when possible and use cloud processing only when the task genuinely needs capabilities that a local workflow does not provide.

Which Macs can run Perplexity Computer locally?

Perplexity Computer local processing requires a supported Apple silicon Mac with 36GB or more of unified memory. Perplexity recommends that memory level because the local model, task orchestration, and execution tools all need to operate on the same machine. Unified memory is the shared memory pool used by Apple silicon processors, graphics hardware, and other system functions.

The 36GB threshold creates an important hardware limitation. Apple’s standard M6 Mac mini configurations top out at 32GB of unified memory, so those configurations do not meet Perplexity’s stated recommendation. Apple lists M5 Pro Mac mini configurations with 48GB or 64GB of unified memory, which meet the requirement. Apple’s Mac mini specifications set out those available memory configurations.

Memory capacity is the main practical filter for this release, not merely whether a Mac has an Apple-designed chip. Users considering a new Mac primarily for local AI should confirm the installed unified memory before buying. A Mac with less than 36GB can still use Perplexity’s cloud features, but it does not meet the company’s recommendation for fully local Computer operation.

What can Perplexity Computer do with local files and Mac apps?

Perplexity Computer can work across local files and Mac apps, including Notes and Mail, when the user grants permission. The local workflow is designed to let the AI interact with information already stored on the Mac without sending that personal data to the cloud. That distinction is useful for people handling private notes, email drafts, or documents that should remain under local control.

Perplexity says the initial local-model choices are Qwen 3.6 and PPLX Pro, its tuned version of Qwen. The model choice affects the AI system that interprets requests, while the Computer framework handles task coordination and execution. Users should still review each requested permission carefully because local processing reduces cloud exposure but does not remove the importance of controlling what an app can access.

Independent reporting also indicates that local Computer can work with Notes, Messages, Mail, and Numbers. The same report says code execution and tool operations run in isolated sandboxes, which are separated environments intended to limit the reach of a process. AppleInsider’s hardware and privacy report describes those app connections and sandboxed operations.

Local app access is most useful when the task depends on information already on a Mac. The approach resembles the privacy argument behind an offline AI note-taking tool, where keeping processing on-device can reduce the amount of personal material sent to an online service. The limitation is that an AI system still needs clear permission boundaries, especially when it can read or act across multiple apps.

When does Perplexity Computer still need cloud processing?

Perplexity Computer still needs cloud processing when a task requires current web information, browser access, connected apps, or stronger reasoning. Perplexity presents cloud use as an approval-based option, which means local operation is not an absolute replacement for every agent request. The distinction matters because many useful AI tasks depend on information that changes after a local model was installed.

Current web information includes material such as recent news, updated product details, and live online results. Browser access and connected apps also introduce data or services that are not necessarily stored on the Mac. A local model can analyze permitted local material, but it cannot independently supply fresh online information without an approved connection to a cloud service or browser-based workflow.

Users should treat the local and cloud options as separate privacy choices rather than assume one mode is always better. Local processing is the better fit for sensitive material already on the Mac. Cloud processing is the better fit for research or tasks that need live services, although users should avoid providing unnecessary personal, financial, or work-confidential data when approving that access.

How private is Perplexity Computer when it runs locally?

Perplexity Computer can keep personal data off the cloud during fully local tasks, provided the user selects local processing and grants only the needed permissions. Perplexity says the model, orchestration harness, and task execution run on the Mac in the local mode. This matters because files and app content do not need to leave the device merely for the AI to process a permitted request.

Local processing improves privacy control, but it does not remove every risk associated with an AI agent. A local agent can still access sensitive information if a user gives it broad permissions across files, Mail, Messages, or other apps. The most sensible approach is to authorize access for a specific task, review what the task needs, and avoid granting broader app access simply for convenience.

Security-conscious users should also keep the Perplexity app and macOS updated, use device encryption, and protect the Mac account with a strong password. Recent AI security concerns, including cases where AI agents were used in website breaches, show why users should not assume automated task execution is harmless in every environment. Local processing reduces cloud exposure, but careful permissions and account security remain necessary.

Who can use Perplexity’s local AI feature on Mac?

Perplexity’s local Computer feature is available in the Perplexity Mac app for Perplexity Pro, Max, and Enterprise subscribers. Perplexity has not described the feature in the supplied announcement as available to every free user, so a paid eligible subscription is part of the access requirement. The hardware requirement also means that many Apple silicon Macs will not qualify for fully local operation.

The feature is most relevant to subscribers who already use Perplexity Computer for work involving personal documents, notes, messages, or email. Local operation provides a clearer boundary for those tasks because the AI workflow can remain on the Mac. That said, users who mainly need web research may gain less from local mode because current information and browser access still require approved cloud processing.

Enterprise users should consider local processing as one privacy control rather than a complete data-governance policy. An organization still needs rules for what employees may authorize, which local files are appropriate for AI processing, and when connected apps or cloud services are permitted. The same caution applies to consumer accounts, particularly when an agent can access communications or financial records.

How should Mac users decide whether local Computer is worth using?

Mac users should choose local Perplexity Computer when privacy-sensitive work outweighs the cost and hardware requirements. The feature is a strong match for users with a supported Apple silicon Mac, at least 36GB of unified memory, an eligible Perplexity subscription, and tasks involving local material that should not be sent to the cloud.

Mac users should not upgrade hardware solely for local Computer unless they have a recurring need for on-device AI task execution. A standard M6 Mac mini with 32GB of unified memory does not meet Perplexity’s recommendation, while an M5 Pro Mac mini with 48GB or 64GB does. The memory gap matters because local AI capacity depends on the available shared memory, not only on processor generation.

Users deciding between local and online AI tools should also consider the type of task. A local workflow is useful for private documents and offline material, while cloud processing remains necessary for live information and connected services. Apple’s growing focus on device-based AI features, including hybrid AI systems that combine local files and cloud actions, reflects the broader tradeoff between convenience, capability, and data control.

What should users do before enabling local Perplexity Computer?

Mac users should confirm their unified memory, subscription eligibility, and intended app permissions before enabling local Perplexity Computer. The feature needs 36GB or more of unified memory, and it is limited to Perplexity Pro, Max, and Enterprise subscribers. Checking those requirements first prevents users from expecting fully local operation on unsupported hardware.

1. Check the Mac’s unified memory configuration and confirm that it has at least 36GB available for Perplexity’s recommended local setup.
2. Open the Perplexity Mac app with an eligible Pro, Max, or Enterprise subscription.
3. Select local processing for tasks involving sensitive local files or Mac app content when the option is available.
4. Review each permission request before allowing access to Notes, Mail, Messages, Numbers, or local documents.
5. Approve cloud processing only when the task needs current web information, browser access, connected apps, or stronger reasoning.

Mac users should stop and contact Perplexity support or their organization’s IT team if the app requests access that is broader than the task requires or if a managed work Mac has restrictions on AI tools. Business users should not bypass device-management rules to enable local AI access, because local processing does not override company policies for confidential data or regulated information.
