Singleton said Muse’s Messages integration on Mac is optional and requires users to enable the Messages connector and grant Muse Full Disk Access through macOS. He noted that users must go through multiple application and system-level permission steps before Muse can access Messages content. According to Singleton, those protections are designed to prevent Muse from bypassing permissions even if the application itself contains a bug. He also said Full Disk Access can be disabled by users. Source: Threads In response to Benzinga’s request for comment, Meta cited Singleton’s response to Wong’s post on X.

Its capabilities include shopping, accessing connected applications and completing tasks on a user’s behalf. In an earlier blog post, Meta said the tech giant "built Muse from the ground up to be a safe, secure, private, and widely available personal AI agent." The backlash also comes at a time when reports about AI agents from OpenAI, Anthropic and Alphabet Inc.’s (NASDAQ:GOOG) (NASDAQ:GOOGL) Google going rogue have also heightened concerns.
