Meta Denies Muse Read Private Mac Messages Without Permission
Meta denies Muse accessed private Mac messages without consent, citing layered permissions, as notification and Marketplace claims test consumer trust.
Summary
Meta on September 30, 2026 denied journalist Jason Aten’s claim that Muse read his private Mac messages without permission. Communications VP Andy Stone said on X that users must enable both Full Disk Access and the Messages connector. Meta Superintelligence Labs executive David Singleton described three permission stages: users grant Full Disk Access, select None, Read only, or Read for Messages, reconfirm through macOS Settings, and restart Muse. Singleton said even an application bug could not bypass these protections.
Aten said Full Disk Access was off when Muse read his messages. Muse attributed the access to synced device notifications, prompting Aten to suspect incoming Mac banner text reached the agent, but Singleton called that explanation AI confusion and cited Meta’s security architecture and bug bounty process. Trust remains vulnerable after lawsuits, FTC violations, fines, and a New Mexico jury’s finding days earlier that Meta misled users in a case stemming from the 2018 Cambridge Analytica breach. Muse remains No. 1 on the App Store, but another user, YouTuber Matt Robb, said a Facebook Marketplace task exposed his address and brought a buyer to his home while he was away. Singleton is investigating that incident.
