OpenAI has introduced a powerful desktop update allowing its flagship AI assistant to integrate directly with Apple Messages on Mac computers. As ChatGPT gains access to Apple Messages, users can now draft replies, summarize lengthy chat threads, and search message histories through simple conversational prompts.

However, this feature grants an external system access to personal communication logs. Consequently, cybersecurity professionals and privacy advocates are raising fresh questions about data exposure.

Backstory: The Tension Between Artificial Intelligence and Privacy

Apple has built its brand identity around strict user privacy and on-device processing. Meanwhile, OpenAI has rapidly expanded ChatGPT’s ability to interact with local desktop applications.

Furthermore, Apple previously restricted third-party attempts to interface with iMessage infrastructure. Yet, this new feature relies on built-in macOS systems like AppleScript and Accessibility tools to read and write text locally.

This update brings ChatGPT into direct competition with Apple’s upgraded Siri. As tech companies compete for desktop intelligence, the line between helpful automation and data vulnerability continues to blur.

Key Security Safeguards and Permission Controls

To ease privacy concerns, OpenAI emphasized that explicit user consent is mandatory before any message processing occurs. Furthermore, the integration does not build a remote, centralized index of personal conversations.

According to technical coverage from Nairametrics, users must manually grant several system permissions:

• Full Disk Access: Enabled directly within Mac System Settings to allow directory scanning.
• Automation Approvals: Specific clearance for ChatGPT to control the Messages app.
• Contacts Access: Permission to link names and phone numbers during messaging.

Despite these user controls, security experts advise caution when connecting large language models to sensitive personal applications.

Cyber Risks and Protecting Personal Data

The risk lies in indirect prompt injection attacks. Malicious code hidden inside untrusted webpages or documents could trick AI tools into reading sensitive messages or executing unauthorized commands.

In December 2025, Nigeria’s National Information Technology Development Agency (NITDA) issued a cybersecurity advisory through CERRT.NG. The agency warned that prompt injection vulnerabilities in advanced GPT models could expose private information or manipulate output memory.

Therefore, users should limit the use of automated integrations on unverified networks. Enabling accessibility permissions only when necessary remains the safest strategy for maintaining total data privacy.
