An on-device malware and adware scan for your Mac

macOS has strong built-in protection, but adware and unwanted apps still slip onto Macs. MacCove Space checks what is installed and running against known Mac adware and malware families, and shows which apps are sending data out over the network — so you know your Mac is clean. It complements macOS security rather than replacing it.

1

Scan

An offline scan checks installed apps, launch agents and running processes. Nothing leaves your Mac.

2

See network activity

Space lists the apps sending data out, so you can spot anything you don’t recognise.

3

Review and remove

Flagged items show why they were flagged. Quit, disable or remove them in a click.

CheckWhat it looks at
Known Mac adware & malwareInstalled apps and their code signatures

The malware scanner is part of Space Unlimited.

Your Mac Care Toolkit

Five tools in one app — everything your Mac needs to stay clean, fast and safe.

Truly unlocking Space on your Mac

Three elements that find your storage, protect what matters and bring your AI into the loop.

Element 01

Tachyon Scan

A deep scan of every corner of your Mac that shows exactly which files are taking up your storage.

Tachyon Scan in MacCove Space
  • Every category, mapped

    Caches, logs, developer junk, Xcode data, AI tool data, app leftovers, Downloads and Trash, sorted into one storage map.

  • Duplicate hunter

    Finds identical files and duplicate photos, even when they have different names and live in different folders.

  • Large & forgotten files

    Surfaces the big files you haven’t opened in months, with a “stale after N days” threshold per category.

  • Risk-graded results

    Everything is graded Safe, Review or Caution, and only the safe items are pre-selected.

  • Entirely on-device

    The scan runs on your Mac. Nothing about your files is uploaded.

Element 02

Memory Alpha

Teach Space what matters. Memory Alpha remembers your rules, so the things you care about never make the cleanup list.

Memory Alpha in MacCove Space
  • Never Touch

    Mark any file or folder Never Touch and it’s left out of every future scan and clean.

  • Protected file types

    Keep whole file types, like every .pdf or .psd, off the cleanup list wherever they live.

  • Remembered verdicts

    Tag a location Always Safe, Requires Review or Caution once. Space remembers it on every scan.

  • Undo, built in

    Cleans go to the Trash by default, so Undo Last Clean is always one click away.

  • Your rules, in one place

    Review or remove any rule from Preferences at any time.

Element 03

Positronic AI Matrix

Control Space and Memory Alpha from the AI you already use, and bring intelligence to every cleanup decision.

Positronic AI Matrix in MacCove Space
  • Bring your own AI

    Connect Claude Code, Claude Desktop or Codex CLI over MCP with a config you copy in one click.

  • Ask in plain English

    “What’s the biggest thing I can safely delete?” Your AI reads the scan report and answers.

  • Command Memory Alpha

    Set Never Touch rules and protected types from chat instead of clicking through settings.

  • Look before you delete

    Your AI can inspect file details and preview text files to explain what something is before it goes.

  • AI proposes, you decide

    Your AI can suggest deletions, but nothing is removed until you approve it in Space.

"I built MacCove Space after my MacBook kept running out of storage and every cleaner I tried either missed half the disk or left me guessing what was safe to delete. So I built one that tells you, and lets your own AI explain why."

Questions & Answers

Everything you need to know about MacCove Space. Can't find what you're looking for? Reach out — we're happy to help.

macOS has built-in protections, but malware and adware still reach Macs. MacCove Space runs an on-device malware scan of what is installed and running on your Mac, checks it against known Mac threats, and lists the apps that are sending data out over the network so you can review, quit or remove them. It complements macOS security rather than replacing it.
MacCove Space is a Mac cleaner and care toolkit. It finds what is eating your storage — cache, system data, app leftovers, old installers, duplicate files and large files — and clears it in a few clicks. It also uninstalls apps completely, scans for malware, shows memory and CPU usage, and helps speed up a slow Mac, all entirely on-device.
Open MacCove Space and run Tachyon Scan. It maps your whole disk into categories — caches, logs, developer junk, Xcode data, AI tool data, leftovers of deleted apps, Downloads and Trash, duplicate files and large, old files — and shows how much storage each one takes. Safe items are pre-selected, so freeing up space on your Mac is one click on Review & Clean.
macOS lumps caches, logs, app support files and developer data into a single “System Data” bar in Storage settings, which makes it hard to see what can go. MacCove Space breaks that storage into named categories, grades each item Safe, Review or Caution, and lets you clear the safe ones, so you can reduce System Data without guessing.
Run a scan and open the Caches category. MacCove Space lists app and system caches with their size, and clearing them is one click. Apps rebuild the caches they still need, and cleans go to the Trash by default, so Undo Last Clean is always available.
Dragging an app to the Trash leaves its preferences, caches, containers and support files behind in your Library. The App Cleaner in MacCove Space removes the app together with every file it scattered, and flags apps you have not opened in a long time so you can uninstall them and free up space.
Yes. It finds identical files and duplicate photos even when they have different names and live in different folders, and surfaces large files you have not opened in months, with a “stale after N days” threshold you can adjust per category.
MacCove Space shows memory and CPU usage by process, like a friendlier Activity Monitor, with live CPU, GPU, memory, network, disk and battery trends. From there you can release memory, release CPU, or quit runaway processes and servers when your Mac runs out of application memory.
A slow Mac is often down to a nearly full disk, too many startup apps and login items, or background services and processes eating memory and CPU. MacCove Space gives your Mac a performance score, shows your login items, launch agents and running services, and lets you disable or quit them — along with clearing storage — to make your Mac faster.
MacCove Space grades every result Safe, Review or Caution and only pre-selects the safe ones, so nothing is removed until you approve it. You can mark any file or folder Never Touch with Memory Alpha, and cleans go to the Trash by default so you can undo.
No. Scanning and cleaning happen entirely on your Mac. MacCove Space never reads file contents off your device or uploads anything.
MacCove Space has a free tier with Tachyon Scan, Memory Alpha for duplicate files, App Cleaner and the system resource manager, with no credit card required. Unlimited adds complete Memory Alpha, Positronic AI Matrix with Claude, the malware scanner and the performance optimizer for $5.99/month or $49.99/year. Cancel anytime.
Most Mac cleaners show you a big number and leave you guessing what is safe. MacCove Space grades every item Safe, Review or Caution, remembers your rules with Memory Alpha so the files you care about never make the cleanup list, and lets the AI you already use — Claude or Codex — explain any file before it goes. It also combines storage cleaning, app uninstalling, malware scanning and performance tools in one app, with a free tier.
No — MacCove Space is a direct download (.dmg) from maccove.com, not distributed through the Mac App Store.
