TrailSift for Mac

Clear the traces other cleaners miss

Your Mac quietly keeps a record of where you've been: the sites you visited, the networks you joined, the people you wrote to. TrailSift finds every trace in the corners ordinary cleaners never look, and clears the ones you choose, leaving your Mac clean and tidy.

A look inside

Everything it finds, before anything changes.

The audit reads more than 30 places and shows what's in each: how many, how big and from when. Then you choose what to clear.

What it finds

The places other cleaners leave alone.

Cache cleaners free space. TrailSift follows the trail: the logs, lists and leftovers that record where you've been, in more than thirty places across macOS and your apps, and the clutter old devices and deleted apps leave behind.

The download log

macOS records every file you download, with the address it came from. Clearing your browser history leaves it untouched.

Old iPhone and iPad backups

Full copies of devices you no longer own, with years of messages and photos. Often the largest forgotten files on a Mac.

History in every browser

Chrome, Brave, Edge, Arc, Firefox, Safari and the smaller ones, with their downloads lists, caches and site icons.

Cookies and site data

Hundreds of sites remembered in every browser, with storage that outlives a cleared history.

Remembered Wi-Fi networks

Every network your Mac has joined, a record of where it has been. Sort by last used and forget the old ones.

Learned typing

Words taught to the spell checker and what the keyboard has learned from you, ready to start afresh.

What deleted apps leave

Support folders, caches and settings of apps you removed long ago, named so you know what they were.

Shell history and print jobs

Commands typed in Terminal, clipboard managers' history, and the record of every finished print job.

Where each download came from

Every downloaded file keeps the address it came from, shown in Get Info, and browsers keep a list of secure sites apart from history.

Addresses Mail remembers

Everyone you've emailed or messaged, kept to suggest again, even people you've removed from Contacts. Forget them one by one.

Location in your photos

Photos say where they were taken, often to a few metres. See which do, and share copies without it.

Code editors and notifications

VS Code's terminal history and recent projects, and the past notifications macOS keeps with their text.

Every place, why it matters and how to clear it yourself is on What TrailSift checks. Weighing up cleaners? See how TrailSift compares with CleanMyMac, CCleaner, OnyX and AppCleaner.

How it works

See everything first. Change nothing you didn't choose.

Audit

A read-only look at every place, with the count, size and dates of what's there. Databases are read from a private copy, and nothing on your Mac is changed.

Choose

Tick what to clear, or let the Clean Up Wizard walk you through it. The review shows exactly what goes: every file, every entry, and the space it frees.

Clear

Files go to the Trash and databases are backed up for a week first. Free space is shown before and after, and the audit runs again so you can see what's gone.

Built on trust

A privacy tool that respects your privacy.

Nothing leaves your Mac

No account, no analytics, no tracking. The only thing TrailSift asks the internet is whether a newer version is out.

Nothing changes until you say

The audit only reads. Every clean-up is previewed in full and confirmed by you, and an app's data is only touched while that app is quit.

Its method is open

Every place it looks is documented with sources, and the audit script is open source under the MIT licence.

Questions

Good to know.

Is it safe?

Yes. The audit only reads, and nothing changes until you review a clean-up and confirm it. Files go to the Trash, and databases are backed up for a week before any entry is removed.

Why does it ask for Full Disk Access?

macOS protects places such as Safari, Messages and iPhone backups until you allow an app to read them. TrailSift works without it and tells you what it can't see; with it, the audit is complete.

Does it replace my usual cleaner?

It complements it. Cache cleaners free space in the obvious places. TrailSift clears the records and leftovers they don't look for.

How do I get help?

Ask in the Itch.studio Discord or email support@trailsift.com. More answers are in the FAQ.
