Why Is My Mac Running Slow? 10 Real Causes and How to Speed It Up
A slow Mac usually comes down to a full disk, memory pressure, startup apps, indexing or heat. Here's how to find which one it is and fix it without guesswork.
Read moreMacCove Space does what other Mac cleaners do — free up disk space, uninstall apps, find duplicates, free up memory and scan for malware — and tells you what's safe to delete, with your own AI to explain any file.
Free Apple notarized Free plan
Most Mac cleaners do one job, or show you a big number and leave you guessing what is safe. MacCove Space combines a full storage map, complete app uninstalls, duplicate finding, memory tools and a malware scan in one app — and grades every item before you delete it.
Tachyon Scan maps 100% of your storage, including System Data.
Safe, Review or Caution on every item, and Never Touch rules it remembers.
Let Claude or Codex review a file or folder and explain why it should go.

Five tools in one app — everything your Mac needs to stay clean, fast and safe.
Clear cache, system data, duplicate files and large files to free up disk space in a click.
Uninstall apps on your Mac completely — preferences, caches and support files included.
An on-device virus and malware scan, plus a network monitor for apps sending data out.
Check memory and CPU usage by process, free up RAM and quit runaway processes.
Speed up a slow Mac by trimming startup apps, login items and background services.
Three elements that find your storage, protect what matters and bring your AI into the loop.
A deep scan of every corner of your Mac that shows exactly which files are taking up your storage.

Caches, logs, developer junk, Xcode data, AI tool data, app leftovers, Downloads and Trash, sorted into one storage map.
Finds identical files and duplicate photos, even when they have different names and live in different folders.
Surfaces the big files you haven’t opened in months, with a “stale after N days” threshold per category.
Everything is graded Safe, Review or Caution, and only the safe items are pre-selected.
The scan runs on your Mac. Nothing about your files is uploaded.
Teach Space what matters. Memory Alpha remembers your rules, so the things you care about never make the cleanup list.

Mark any file or folder Never Touch and it’s left out of every future scan and clean.
Keep whole file types, like every .pdf or .psd, off the cleanup list wherever they live.
Tag a location Always Safe, Requires Review or Caution once. Space remembers it on every scan.
Cleans go to the Trash by default, so Undo Last Clean is always one click away.
Review or remove any rule from Preferences at any time.
Control Space and Memory Alpha from the AI you already use, and bring intelligence to every cleanup decision.

Connect Claude Code, Claude Desktop or Codex CLI over MCP with a config you copy in one click.
“What’s the biggest thing I can safely delete?” Your AI reads the scan report and answers.
Set Never Touch rules and protected types from chat instead of clicking through settings.
Your AI can inspect file details and preview text files to explain what something is before it goes.
Your AI can suggest deletions, but nothing is removed until you approve it in Space.
Free up space, speed up a slow Mac and keep it safe from malware, all from one app that keeps everything on your Mac.
