Support
Most questions about Neatwise: Mac Cleaner are really questions about a Mac that is running out of space. Those are answered in the guides, which cover the manual method as well as the product one.
Start with a guide
- How to Clean Mac System Data
To reduce System Data on a Mac, clear the parts that are removable — caches, logs and temporary files — remove support data belonging to applications you no longer use, and accept that the rest is macOS itself and cannot be cleared.
- How to Clean Up a Mac
To clean up a Mac, work in a fixed order: clear the accumulated folder, remove duplicates, uninstall unused applications with their support files, clear caches, then empty the Trash. Repeat it on a schedule so the disk stops filling up between cleanups.
- How to Find Duplicate Files on Mac
To find duplicate files on a Mac, compare file contents rather than filenames. Group the files that are genuinely identical, then keep one copy of each group and remove the rest — checking first that nothing references the copy you remove.
- How to Find Large Files on Mac
The easiest way to find large files on a Mac is to order files by size rather than browsing folders. Review the largest items from the top of the list and check what each one is before removing it.
- How to Find Old Files on Mac
To find old files on a Mac, sort folders by date modified or date created. Ordering by date turns a folder into a timeline, which makes the boundary between current and accumulated material obvious.
- How to Free Up Storage on Mac
To free up storage on a Mac, first identify what is consuming the disk. Large files, duplicate files, unused applications, old downloads and accumulated caches are the usual sources. Remove them in that order, largest and most redundant first, and empty the Trash so the space is actually released.
- How to Remove Unwanted Files from Mac
To remove unwanted files from a Mac safely, classify each file first — what created it, whether it can be recreated, and whether this is the only copy — then remove only the files you can account for, and empty the Trash so the space is actually released.
- How to Uninstall Apps on Mac
To uninstall an app on a Mac completely, remove the application bundle and the support files it created. Dragging the app to the Trash removes only the bundle; preferences, caches, containers and application support folders remain and have to be removed separately.
- What Is Taking Up Space on My Mac?
To find out what is taking up space on a Mac, start from the storage report, which breaks usage into categories, then look inside the largest categories for the folders and files responsible.
- Why Is My Mac Storage Full?
A Mac startup disk usually fills up from media libraries, accumulated caches and support data, duplicate files, local snapshots, or large files left over from finished projects — not from the documents you can see on the Desktop.
Questions about the product itself
What it is, which platforms it runs on, how it is distributed, where the price is shown and how removal works are all answered on the FAQ page, with the underlying facts on the product knowledge page.
Common questions
The questions the Neatwise: Mac Cleaner support documentation answers most often.
- Why does it ask for folder access on first launch?
- The macOS App Sandbox only lets an app reach a folder you have explicitly granted. Choose the folder in the system open panel — your Home folder is the recommended one — and click Grant. The grant is used for local scanning and cleaning only, and you can review or revoke it at any time in Preferences → Permissions.
- How do I revoke a folder I granted?
- Open Preferences → Permissions and remove the folder from the authorised list. Neatwise loses access to it immediately and cannot regain it without you granting it again.
- Where do cleaned files go?
- To the system Trash first, so you can restore anything you did not mean to remove. Categories that involve personal files — Downloads, installers, the Trash itself — are unchecked by default and marked Caution; they are only cleaned after you confirm.
- Why do some files say they cannot be deleted?
- They are owned by root or protected by macOS, such as the system logs under /Library. App Store rules do not allow an app to escalate privileges, so Neatwise cannot remove them. The dialog offers a Copy Command button so you can complete it in Terminal with an administrator password.
- How are scan results categorised?
- Into System Junk, App Junk and Internet Junk. Each subcategory is labelled Recommended (checked by default, safe to remove) or Caution (unchecked by default, review before cleaning).
- How do I re-enable a login item I disabled?
- Toggle it back on in Login Items. The change is written as a plist flag and persists across restarts; some services only take effect at your next login.
- Is my data uploaded anywhere?
- No. Scanning, analysis and cleaning all happen on your Mac. There are no analytics or advertising SDKs and nothing is collected. The only network activity is the Speed Test, which you start yourself and which carries no personal information.
- Can an uninstall be undone?
- Yes — the app bundle and its leftovers go to the Trash first. If a deletion fails, for example because the app is owned by root, it stays in the list with a clear reason rather than being reported as removed.
- Which macOS versions are supported?
- macOS 26.5 or later, on both Apple Silicon and Intel Macs.
Contact
For anything not covered above — a behaviour that looks wrong, a correction to a page, or a privacy question — the developer's issue tracker is the fastest route:
github.com/yijun1/maccleaner/issues
When reporting a problem, include your macOS version, the Neatwise version, the steps that reproduce it and any screenshots. If the problem is about a specific file or folder, say what kind of location it was rather than naming the file.
If your question is about a purchase, a refund or a download that is not appearing, it is handled by the Mac App Store rather than by this site, because the Mac App Store processes the transaction.
What this site still does not answer
One question is deliberately left unanswered here: the price. It is shown on the Mac App Store listing, which is the only place it is kept in step with what you actually pay. A figure copied onto this site would go stale the first time pricing changed, so it is not published — see Pricing for what that means in practice.
Everything else on this site is drawn from the fact layer, and every fact there names where it was verified. The privacy page shows that provenance most clearly.
