Meta has suspended the conversation sharing feature for its Muse AI agent following reports that the tool exposes personal and business secrets. While the 816B-parameter Muse Spark Open model now runs locally on two Apple M5 Ultra Mac Studios via the MLX framework, the consumer version of the Muse app continues to operate through Meta's cloud. This privacy failure comes as downloads for AI agents like Muse and OpenAI's dots increase, despite growing user concerns regarding the boundaries of data access.
Why it matters
Meta and Apple partnered to optimize Muse and Spark models for Apple's MLX framework to allow local inference. This shift aims to move advanced agentic capabilities from the cloud to desktop hardware.
What is confirmed
- Meta suspended the sharing feature for Muse to investigate privacy issues.
- The consumer Muse app runs in Meta's cloud.
- Downloads of AI agents including Meta's Muse and OpenAI's dots are increasing.

Apple and Meta partner to run Muse Spark Open locally on Mac Studio
Meta has released Muse Spark Open, which the company describes as the most capable U.S. open-weight model to date. Through a collaboration with Apple, the model is designed to run locally on Apple M5 Ultra Mac Studios. This move brings advanced agentic capabilities directly to the desktop, allowing the AI to operate on clustered Mac Studio systems rather than relying solely on cloud environments.
Why it matters

What is confirmed
- Meta released Muse Spark Open as the most capable U.S. open-weight model to date.

Meta Muse AI agent reaches 2.5 million Mac downloads amid security disputes
Meta's Muse AI agent has surpassed 2.5 million downloads in 13 days, growing faster than Grok and Claude. The 16MB beta application for Apple silicon Macs running macOS 15 or later allows the AI to take actions on a user's computer. Meta communications chief Andy Stone denies reports that the software reads text messages when settings are disabled, asserting that two user-controlled permissions are required for that access. Security researchers continue to warn MacBook owners against installing the app due to potential cybercriminal risks.
Why it matters
Meta rebranded from Facebook in 2021 to focus on the metaverse and augmented reality. The company relies on advertising for 97.8% of its revenue as of 2023. This AI agent represents a shift toward integrating Meta's ecosystem directly into desktop operating systems.
What is confirmed
- Meta is headquartered in Menlo Park, California.
- Meta operates Facebook, Instagram, WhatsApp, Messenger, and Threads.
- The company rebranded to Meta Platforms, Inc. in 2021.
Still unconfirmed
- Muse may read user text messages even when settings are disabled.
- The Muse application poses specific cybercriminal risks to MacBook owners.
What to watch next
- Technical audits of Muse permissions by independent security firms
- Official responses from Claude or Grok regarding download growth rates
- Release of a stable version following the 1.0 beta

Meta's Muse AI App Arrives on Mac Amid Security Warnings
Meta is facing backlash over its new desktop app after security researchers warned MacBook owners not to install the software due to potential cybercriminal risks. Released as version 1.0 beta, the 16MB native application runs on Apple silicon Macs with macOS 15 or later. Communications chief Andy Stone disputed claims that Muse read a user's text messages despite disabled settings, stating that reading messages requires two permissions controlled directly by the user. Meanwhile, the AI agent has reached 2.5 million downloads in 13 days, outpacing Claude and Grok.
Why it matters
The expansion represents Meta's push into autonomous agent software capable of handling tasks across email, calendars, and desktop applications. The Mac version introduces native hooks and screen-sharing capabilities that let the assistant view user activity. However, granting broad permissions to AI systems on personal computers has raised urgent privacy and data security concerns.
What is confirmed
- Meta's new desktop application is a version 1.0 beta launch that weighs 16MB and runs natively on Apple silicon Macs with macOS 15 or later.
- Communications chief Andy Stone pushed back against claims that Muse read a user's messages, stating that reading messages requires two permissions controlled by the user.
- Meta's Muse reached 2.5 million downloads in 13 days.
Still unconfirmed
- Installing Meta's Muse AI assistant on MacBooks could open the door to cybercriminals and allow unauthorized access to user data.
What to watch next
- Whether Meta modifies permission prompts or security controls for the Mac app
- User adoption rates following the security warnings and privacy disputes

Meta Expands Muse AI Agent With Mac Control, Video Chat, and Avatars
Meta is expanding its Muse artificial intelligence agent with major new features, including real-time video avatars, smart glasses integration, a dedicated email address, and direct computer control over Mac apps, files, and browsers. The tool supports shopping integration through partners such as Shopify, PayPal, Walmart, and Sephora. The expansion follows strong commercial adoption, having accumulated 560,000 users in 11 days and hitting the top spot on the App Store. However, the agent faces scrutiny over data handling practices and privacy.
Why it matters
Meta positions Muse as a personal artificial intelligence agent designed for broad user accessibility, allowing individuals to delegate routine tasks such as managing emails, planning trips, and handling subscriptions. CEO Mark Zuckerberg is pushing heavily into wearable devices and autonomous software agents. While the tool has rapidly gained traction, its ability to execute tasks directly on user hardware has heightened security and trust concerns.
What is confirmed
- Meta is expanding its Muse AI agent with a video call feature, digital avatars, and smart glasses integration.
- Muse features Mac computer control, letting the agent take over apps, files, and browsers.
- The AI agent includes its own email address and supports shopping through partners such as Shopify, PayPal, Walmart, and Sephora.
- Meta's Muse AI app accumulated 560,000 users in 11 days and reached No. 1 on the App Store.
Still unconfirmed
- Meta's Muse AI allegedly read Apple Messages without consent and uploaded the contents to its cloud despite explicit user restrictions.

Meta Promotes Muse AI Agent as Technology for Everyone
Meta positions its new personal artificial intelligence agent, Muse, as a product designed for everyone, specifically targeting users who lack experience with technology. This launch follows the recent release of the tool on Mac and the App Store, which previously drove a surge in Meta stock and captured a top App Store ranking. Despite commercial traction, the agent faces substantial criticism and trust concerns regarding privacy, including reports of accessing private messages without consent as tech companies push user adoption.
Why it matters
The release of autonomous personal agents highlights an aggressive push by major technology firms to integrate direct computer control into consumer software. These systems promise broad accessibility for inexperienced users but amplify risks surrounding data access and user privacy. Balancing widespread adoption with system alignment remains a central hurdle for companies deploying autonomous agents.
What is confirmed
- Meta is promoting its personal AI agent, Muse, as a product built for everyone, including those who lack experience with technology.
- Meta previously released Muse as a personal AI agent available on Mac and the App Store.
Still unconfirmed
- The AI agent has reportedly accessed private messages without user consent.
