DeviceInfo is a free, open-source Mac utility that surfaces the hardware and software specifications of your machine in one clean, readable interface — no Terminal spelunking required.
What is DeviceInfo?
DeviceInfo is a lightweight macOS application that reads your Mac's system profile and presents it in an organised, scannable dashboard. Where macOS buries specs across System Settings, System Information, and a handful of Terminal commands, DeviceInfo pulls everything into a single window. I reach for it any time I'm troubleshooting a mystery crash or filling in a support ticket and need to answer "exactly what chip, how much RAM, what macOS build?" in under ten seconds.
What does DeviceInfo do best?
DeviceInfo excels at giving you an instant, glanceable snapshot of your machine without the noise that ships with Apple's own System Information app. The layout prioritises the facts most people actually need: processor family, chip model, core counts, installed memory, storage breakdown, macOS version, and build string. It doesn't try to be an activity monitor or a benchmark suite — it just tells you what you've got.
That focus is its biggest strength. I've used iStat Menus and coconutBattery for live monitoring, and they're excellent for their purpose — but neither answers the "what exactly is this machine?" question as cleanly as DeviceInfo does. It's the difference between a dashboard and a fact sheet.
Is DeviceInfo free?
Yes — DeviceInfo is completely free to download and use. The source code is published on GitHub under an open licence, so you can inspect exactly what it reads and how. There are no in-app purchases, no premium tier, and no account required.
Who should use DeviceInfo?
DeviceInfo is most useful for three kinds of Mac user. First, developers who jump between machines and need to confirm environment specs before running a build. Second, IT administrators who support a mixed fleet of Intel and Apple Silicon Macs and want a fast way to confirm chip architecture remotely or in person. Third, power users who resell or buy second-hand hardware — having a trustworthy spec readout to screenshot and share cuts down on ambiguity in listings.
If you only ever use one Mac and never need to communicate its specs to anyone else, the native About This Mac screen will probably suffice. DeviceInfo earns its keep the moment you find yourself cross-referencing multiple panels or copying specs into a spreadsheet.
What are the best DeviceInfo alternatives?
The closest native alternative is Apple's own System Information app (hold Option and choose Apple menu → System Information), which is comprehensive but intimidating — it was designed for Apple's engineers, not everyday users. GPU Monitor Pro and iStat Menus surface similar hardware data but bundle it with continuous live monitoring, which is overkill when you just want a one-time readout. For chip-specific detail on Apple Silicon, System Information still wins on raw depth; for battery health specifically, coconutBattery is the go-to. DeviceInfo sits in the middle: friendlier than System Information, simpler than iStat Menus, free where coconutBattery charges for Pro features.
How does DeviceInfo compare to System Information?
Apple's System Information is exhaustive — it exposes every PCI slot, every USB controller, every memory DIMM. That depth is genuinely useful for hardware diagnostics, but it takes time to navigate and the data is dense. DeviceInfo trades completeness for legibility: it gives you the 80 % of specs that matter in 100 % of support conversations, formatted for a human rather than a hardware engineer. I keep both installed. DeviceInfo is my first stop; System Information is my deep-dive when something is actually wrong.
Because DeviceInfo is open source and actively maintained on GitHub, it also tracks new Apple Silicon variants promptly — a practical advantage over closed utilities that lag behind new hardware announcements.
