System monitor for macOS · Native on Apple silicon # See everything your Mac is doing. Tidix goes deeper than Activity Monitor: every core, the GPU and Neural Engine, every disk and network interface, and the apps that use them most. All in one fast, native app. [Buy Tidix — from $5](https://tidix.app/#pricing) [Download free](https://tidix.app/download) - One-time purchase - 14-day refund - macOS 13 or later ![Tidix Summary page with CPU, memory, GPU, temperature, network, and disk cards, and the top apps by CPU over the last 24 hours](https://tidix.app/screenshots/summary-dark.png) - Swift + AppKit: **Native. No Electron.** Built for macOS, feels like macOS. - Lightweight: **A fraction of one core.** Pages refresh only while you're looking. - Private: **Your data stays home.** Monitoring data never leaves your Mac. - 4 languages · light & dark: **Yours, your way.** Light or dark, with your accent color. ## Everything Activity Monitor leaves out. Sampling runs in the background and pages refresh only while visible, so Tidix uses a fraction of a core instead of heating one up. ### Every core, disk, and network interface on its own. Performance lists each device on its own: CPU, memory, GPU, Neural Engine, every physical disk, every network interface in use, power, and thermals. Pick one for its live chart over the last 1, 5, or 30 minutes and the apps that use it most. ![Tidix Performance page with a device list, a CPU chart, a graph per core, and CPU use by app](https://tidix.app/screenshots/performance-dark.png) ### Find the process that's draining your Mac. A process tree or a flat list with app icons and columns for CPU, memory, threads, disk reads and writes, power draw, and wakeups. Filter by apps, background processes, or owner. Quit a process or its whole tree, pause it, send it a signal, change its priority, or sample it. ![Tidix Processes page with a process tree, CPU, memory, and power draw columns, and the details of the selected app](https://tidix.app/screenshots/processes-dark.png) ### Every app on your Mac, and what starts with it. Installed apps with their version, source, last use, and size on disk. Startup items list the system extensions, drivers, and kernel extensions that apps installed, each linked to its app, with a switch to turn it on or off. ![Tidix Apps page with installed apps and their version, source, last opened date, and size](https://tidix.app/screenshots/apps-dark.png) ## And there's more. ### App details Click an app anywhere to see its state, last use, uptime, version, size on disk, processes, live usage, and up to 30 days of history. Uninstall it by moving the app and its related files to the Trash. ### Top apps over time Summary ranks the apps that used the most network, CPU, memory, energy, or disk over the last hour, 24 hours, 7 days, or 30 days, from a history saved on your Mac. ### Quick search Search across Tidix with ⌘F or ⌘K and jump straight to a process, an app, or a disk. ### Runs the way you work Monitoring profiles from Power saving to Diagnostic, launch at login, running in the background, a global keyboard shortcut, and the units you prefer. ### Safe updates Tidix checks for updates at most once a day and installs one only after you agree and its signature is verified. ### Your language, your look English, Spanish, French, and German, switchable without a restart. Light or dark, or follow your Mac, with your own accent color. ## Light on your Mac. Quiet about you. Tidix contacts the license service only to activate, check, and deactivate.

Write to [support@tidix.app](mailto:support@tidix.app). ### How do device licenses work? Each license covers a set number of Macs. Activating Tidix on a Mac takes one seat, and activating the same Mac again doesn't take another. When every seat is in use, deactivate one in the Tidix app before adding another Mac. ### I got a new Mac. How do I move my license? Deactivate the license in Tidix on the old Mac. The seat is free right away, so you can activate the new Mac. ### I lost my license key. Now what? Your license key is in the checkout email. You can also sign in with the email you bought with: your account lists every license key for that address. ### Does Tidix need to be online? Tidix contacts the license service only to activate, check, and deactivate. If it can't reach the service, it keeps working for up to 30 days after the last successful check. Your monitoring data never leaves your Mac. ### What do I need to run Tidix? macOS 13 or later. Tidix is native on Apple silicon. A few readings, such as other users' processes and energy counters, need the optional privileged helper, which you can turn on in Settings. ### Who handles the payment? Checkout runs on Paddle, which acts as the reseller and merchant of record. Paddle handles payment, sales tax, and your receipt. ## Stop guessing. Start seeing. Every core, sensor, disk, and process on your Mac, in one native app you pay for once. [Buy Tidix — from $5](https://tidix.app/#pricing) One-time purchase · 14-day refund · macOS 13 or later
