OpenAI shipped a new Apple Messages plugin for ChatGPT on August 20 that grants the AI system access to read, search, and send iMessages, SMS, and RCS texts on Mac computers. The move sparked swift privacy backlash, with critics warning the integration exposes sensitive user data. Apple shares fell 1.7% to $311.30 on Tuesday amid broader market pressure, while Meyka rates the stock a B with a neutral stance.

What the ChatGPT Messages plugin actually does

The plugin, available on all ChatGPT plans for macOS, lets users ask the AI to search message threads, summarize conversations, draft replies, and send texts on their behalf. It works in ChatGPT Work and Codex but not in regular chats. By default, ChatGPT requires user approval before sending any message, though users can disable this safeguard. The feature only runs on Apple Silicon Macs, not Intel machines.

Privacy guardrails and the approval question

OpenAI told Bloomberg the plugin processes data locally on each user’s device and does not create an index of all messages. OpenAI’s documentation warns against enabling persistent approval, stating it removes the final chance to review a message before ChatGPT sends it. The plugin requires macOS permissions including Full Disk Access, granting broad system visibility.

Why the timing matters for Apple

The integration lands as AI agents gain broader system access. Critics note Messages contains credentials, medical threads, breakups, and two-factor codes, making it a sharper privacy edge than other integrations. Apple has not publicly commented on the plugin or its privacy implications for iMessage users.

What investors should watch

Meyka rates Apple a B on neutral fundamentals, with a 12-month price target of $290.24 versus the current $311.30. The stock trades at a 35.7 PE ratio, well above historical averages, and faces headwinds from a debt-to-equity ratio of 0.78. Analyst consensus leans Buy (21 Buy, 8 Hold, 6 Sell), but the privacy controversy adds regulatory risk if lawmakers scrutinize AI access to user communications.

Final Thoughts

OpenAI’s iMessage plugin expands AI reach into Apple’s most private channel, triggering immediate privacy debate. With Meyka grading Apple a B and price targets below current levels, the stock faces near-term volatility if regulators demand tighter AI guardrails.

FAQs

Only Apple Silicon Macs running the ChatGPT desktop app. Intel Macs, iPhones, iPads, and web ChatGPT do not support the plugin.

Why did Apple stock fall on this news?

AAPL dropped 1.7% to $311.30 on Tuesday amid broader market weakness. Privacy concerns around AI access to Messages may add regulatory risk for Apple long-term.
