Your Mac shouldn’t be a f***ing mystery.

Yes - every install includes a full 7-day Pro trial from first launch. No email or signup required. After 7 days the app keeps working as a free inspector forever; only the 1-click cleaning and kill features need the $9 Pro license. Clearing the app's data does not reset the trial.

Monitoring and inspection are free forever. Pro adds the actions: memory purge, APFS purgeable-space reclaim, Empty Trash, Deep Clean, the 1-click dev server killer, the heavy-app killer, and every Space Inspector cleanup. It is a one-time payment for up to 3 Macs, with all 2.x updates included forever.

We refuse to charge an arbitrary "Silicon Valley tax." A Mac utility shouldn't cost a week of groceries outside the US. Checkout automatically localizes prices across 130+ countries ($9 USD in North America/Europe, ₹399 + GST in India with instant UPI / Google Pay). One license works on up to 3 of your Macs with lifetime updates.

macOS 12 Monterey or later (Ventura, Sonoma, Sequoia and beyond). WTMemory ships as a universal binary, so it runs natively on Apple Silicon (M1 through M4) and on Intel Macs. There is no installer, no kernel extension, and no background daemon - it is a single 794 KB app.

The app keeps running and keeps monitoring your RAM, CPU and disk for free, and the Space Inspector still scans and diagnoses. Only the one-click cleaning and process-killing actions ask for a Pro license. You get a one-time heads-up two days before expiry and a single reminder after it lapses - no nagging.

No. There is no signup, no login, and no email required to use the app or start the trial. An email address is only involved when you buy Pro, because Dodo Payments sends your license key there.

For anyone who wants to understand and control their Mac rather than run a black box, WTMemory is the strongest alternative. CleanMyMac X is a 380+ MB background suite costing $39.95/year that runs persistent daemons and telemetry. WTMemory is a 794 KB native Swift binary that runs 100% offline, costs $9 once, covers 3 Macs, and handles the developer realities CleanMyMac ignores - killing runaway dev servers, clearing buried Ollama/HuggingFace AI weights, and reclaiming inactive unified memory. Read the full CleanMyMac comparison.

Three differences matter most: size and footprint (794 KB versus 380+ MB with no background daemon), price model ($9 once for 3 Macs versus $39.95 per year for 1 Mac), and developer awareness (WTMemory understands vite, next-server, workerd, Ollama weights and Xcode DerivedData - things generic cleaners skip entirely).

DaisyDisk is only a passive disk visualizer with circular color charts. It cannot monitor live unified RAM pressure, purge inactive memory, kill rogue processes, or clean AI model hoards. WTMemory is an active control panel and process assassin that inspects and fixes memory and storage bottlenecks directly from your macOS menu bar.

Because it is written in Swift against native macOS frameworks instead of shipping a bundled browser engine. There is no Electron runtime, no JavaScript framework, no telemetry SDK, and no updater daemon - just the system APIs and a single 794 KB binary. Smaller code means less to go wrong and nothing running in the background when you don't need it.

It removes specific causes of slowdown rather than promising magic. Freeing inactive unified memory, clearing APFS purgeable space, and killing orphaned dev servers or runaway app helpers restores responsiveness without a reboot. If your Mac is slow because of a failing drive or a genuinely underpowered CPU, no cleaner - including this one - can change that.

macOS APFS allocates "purgeable" space for local Time Machine snapshots and system caches. Even when you delete big files, macOS holds onto this space until the disk is nearly full. WTMemory calls native Darwin kernel purge routines to force-flush purgeable blocks immediately without rebooting your computer.

Purging only clears inactive and cached memory, which macOS rebuilds automatically as your apps ask for it. The short-term effect is more free RAM for the app you are actually using; the OS re-caches what it needs. Nothing permanent is removed and no data is lost.

Local AI models (Ollama, Hugging Face transformers, LM Studio, ComfyUI checkpoints) hoard tens of gigabytes inside hidden paths like ~/.ollama/models and ~/.cache/huggingface. WTMemory inspects these directories, displays your exact active and inactive model weights (Llama 3, DeepSeek R1, Mistral, LoRAs), and allows 1-click safe cleanup to reclaim 20-80 GB of SSD space.

Yes. The dev server killer finds orphaned background processes such as vite, next-server, workerd, nodemon and esbuild and ends them in one click, releasing the ports and the CPU cycles they were holding. It also clears the build caches - Xcode DerivedData, pnpm, npm, Yarn, Bun, Cargo and Gradle - that quietly pile up to tens of gigabytes.

On a typical working Mac, far more than most people expect: Xcode DerivedData and simulator runtimes in the tens of gigabytes, Docker virtual disk images in the teens, and package-manager stores from pnpm, npm, Bun, Cargo and Gradle adding several more. Because these rebuild on demand, they are among the safest large wins - the homepage scan panel shows a labelled illustrative example.

Never. WTMemory targets only safe macOS system caches, disposable derived data, orphaned build artifacts, and user-selected AI weights. It never modifies your personal documents, photos, git repositories, or project code. It runs with standard user permissions and zero kernel extensions.

Safe Mode is on by default, which means everything WTMemory cleans is moved to the macOS Trash rather than deleted outright - so you can put it back. Only if you deliberately untick Safe Mode do items get removed permanently.

No. WTMemory contains no analytics and no telemetry, and never uploads your files, process list, or usage data. The single network call in the entire app is license key activation and periodic re-validation against Dodo Payments - and that request contains only your key and a device name.
