Mac users can now call on Google’s agentic AI, Gemini Spark, to automate tasks on their desktop and bridge the gap between Google Workspace and their local apps and files. But you should still be cautious when granting Gemini access to your data and workflows, as AI agents can introduce security risks.

Google first announced Spark at I/O 2026 back in May, promising a rollout to the Gemini macOS app at some point this summer. That time has come—the AI agent is now available in beta for Google AI Ultra subscribers on macOS in the U.S. Google has said users will also be able to run Gemini Spark tasks on desktop remotely from their phones, though that functionality is not live yet.

Gemini Spark can automate workflows on macOS

Spark turns Gemini into a personal AI agent that can complete multi-step tasks based on your requirements, even if your device is turned off. When given access to desktop files and apps, it can, for example, sort downloaded PDFs into specific folders or create a budget in Sheets using invoices saved to your computer and update that worksheet on a regular schedule.

Google is also launching integrations with Tasks and Keep as well as apps like Canva, Dropbox, Instacart, OpenTable, and Zillow Rentals, so Gemini Spark could theoretically translate notes into action items, share files, submit your weekly grocery order, or make a dinner reservation. These will be available on web and mobile first, with a rollout planned for macOS “in the coming weeks.”

Agentic AI comes with risks

Google has emphasized that Gemini Spark works on your commands: It only has access to the files and apps you permit it to use, and it won’t spend money or take other high-stakes actions without your consent. However, handing control over to AI isn’t without risk, and you should proceed with caution when allowing Spark (or any other AI agent) to read your files and act on your behalf. At the very least, an AI agent could share sensitive information or send a message you wish it hadn’t.

One known security risk is a prompt injection attack, in which hackers trick AI into following their malicious instructions instead of your legitimate ones. When agentic AI acts autonomously without user approval, there’s no safeguard against data being shared, malware being downloaded, or a fraudulent purchase being made. If you’re going to let Gemini Spark or another AI agent take action on your behalf, you should limit what it can access, require manual review for certain tasks, and enable multi-factor authentication on connected accounts to minimize the risk from threat actors.
