Storage Cleaner Expert
See what's filling your Mac. Clear only what you choose.
Finds caches, build files, simulators, installers and other space hogs, explains each one, and moves only the items you check to the Trash.
For macOS 15.6 or later.
Works without an AI account.
An animation of the Storage Cleaner Expert window. It scans Macintosh HD and finds caches, installers, build output and project dependencies, with large items listed separately. A person checks six categories, confirms Move to Trash, then empties the Trash, and free space grows from 25.4 GB to 63.6 GB.
Move 6 Items to the Trash?
Thirteen kinds of clutter, sorted by how safe they are to clear.
The bar shows what the scan above found on a test Mac. Point at a category to find it in the bar.
Caches & Junk
Apps and macOS make these again when they need them.
App CachesCaches and saved state that apps, including browsers, rebuild on their own.
System Caches & Temporary FilesTemporary files and caches that macOS and apps leave behind.
Logs & DiagnosticsLogs and crash reports, rarely needed after a few days.
Updates & InstallersmacOS installers, device updates and downloadable app content.
TrashItems already in your Trash.
Developer
Found in your projects and developer tool folders. Rebuilt the next time you build or install.
Build OutputDerived Data and build folders, made again on the next build.
Project Dependenciesnode_modules, virtual environments and other packages your projects reinstall.
Developer ToolsPackage caches, simulators, SDKs and toolchains from Xcode, Android Studio, Homebrew and more.
Large Items
Big, and some are hard to get back. They're listed for you to judge, never chosen for you.
AI ModelsLocal models from Ollama, LM Studio, Hugging Face and Whisper.
Virtual Machines & ContainersDocker data and virtual machines from Parallels, UTM, VMware and others.
Archives & BackupsiPhone and iPad backups, Xcode archives and other archives.
GamesSteam games and workshop content.
Large Personal FilesFiles of 500 MB or more in your home folder.
Nothing moves until you check it.
Cleanup happens in four steps, and the app never takes the next one for you.
- 1
Scan
Reads names, sizes and dates in the places you pick. Nothing changes while it looks.
- 2
Review
Each suggestion says what it is and whether it comes back on its own. Large items are never checked for you.
- 3
Move to Trash
Every item is checked again right before it moves. Anything that changed stays put, and you're told why.
- 4
Empty Trash
A separate step with its own warning. Until you take it, you can put anything back from Finder.
Know what a folder is before you let it go.
A built-in catalog recognizes most folders the moment you open them. When it can't, Jev, the app's AI classifier, names the rest and says whether it comes back.
Still unsure? Ask about that exact folder in plain words, and the answer is about what's on your Mac, not a general guess.
AI is optional and uses your own OpenRouter key, only after you allow it.
- What it is
- iOS Simulator devices from Xcode
- Comes back?
- Yes, Xcode makes them again when needed
- Identified by
- Built-in catalog
Can I delete the iPhone 15 simulators?
Yes. These 6 devices run iOS 17.5, and none of your installed Xcode versions use it. Removing them frees 14.2 GB. If you need one later, Xcode downloads it again.
Scanning stays on your Mac.
The app runs in App Sandbox and reads only what you grant. There's no tracking, no ads and no telemetry. Your API key lives in the Keychain on this Mac only.
Try the switch to see exactly what changes when you turn AI on.
Nothing about your files leaves your Mac. Scanning, suggestions and Move to Trash all work this way.
Only after you allow it, folder details go over HTTPS to OpenRouter and the AI provider serving the model you chose, using your own API key.
- Sent
- Names and paths, sizes, dates, file types and your question
- Asks first
- A short text excerpt from one file, named before it's read
- Never sent
- Whole files, and nothing from your scan while this is off
Also in the app
- Uninstall apps with their leftovers
- Finds the data folders an app leaves behind, lets you pick which go with it, and points you to the vendor's own uninstaller when there is one.
- Cleanup History
- Every move is recorded with where it came from and where it went, so you can find it in the Trash later.
- Free space over time
- A small chart in the sidebar shows how your free space has changed from scan to scan.
- Leave things out
- Exclude folders from scans and hide suggestions you never want to see again.
Questions
Does Storage Cleaner Expert delete files permanently?
No. Move to Trash puts items in your Trash, where you can put them back from Finder. Emptying the Trash is a separate step that warns you first, and it's never done for you.
Do I need an AI account to use it?
No. Scanning, suggestions and cleanup work without one. AI is optional: add your own OpenRouter key and allow external analysis to get folder identification and chat.
What can it see on my Mac?
Only the disk or folders you choose in an Open panel, as App Sandbox requires. It reads names, sizes, dates and a few known settings files, not your documents. Full Disk Access is optional and only helps with some protected folders.
Is it useful if I'm a developer?
Yes. It finds Xcode Derived Data and simulators, node_modules and virtual environments, Homebrew and other package caches, Docker data and local AI models, and tells you which of them rebuild on their own.
What does it keep after I quit?
Short report summaries and a Cleanup History of what moved and where. Folder lists, AI answers and chats are discarded when you quit.
Which Macs does it run on?
Any Mac running macOS 15.6 or later.
