Can a disk-access permission bypass an AI app’s message switch?

TECHNOLOGY & SOFTWARENEEDS REVIEWUpdated:

Apple is reported to be changing macOS Full Disk Access permissions after saying some developers use the setting in ways that can expose files, mail, messages, and browsing history without users fully understanding the consequences.

Can a disk-access permission bypass an AI app’s message switch?

The scope of a separate connector versus Full Disk Access

The announcement followed a columnist’s claim that Meta’s Muse AI referred to an Apple Messages conversation even though he says he had not allowed it to read messages. Meta said Muse needs both Full Disk Access and a separate Messages connector to access message content. A macOS security expert disputed that distinction, saying Full Disk Access can read non-root files including chats.

What makes the account unusual is the gap between a supposedly separate opt-in Messages switch and the broader reach reportedly available through a system-wide permission. Apple did not name Muse or Meta, and the report does not establish that Apple’s change was prompted by that incident.
