Free Up Space in One Tap

Most of a full Mac isn't your work. It's caches, old local backups and data left behind by apps: things you never chose to keep. A one-tap clean-up can free up space from all of that, as long as it sticks to steps you'd never need to undo.

What fills a Mac when you're not looking?

If you run local AI models, build software or edit video, the storage bar doesn't move in a straight line. It jumps. A model download here, a build cache there, a set of local snapshots you didn't ask for, and suddenly macOS says the disk is almost full in the middle of an export.

• App caches. Browsers, creative tools, package managers and AI tools all keep them, and nothing trims them on a schedule.
• Local snapshots. macOS keeps them on your internal disk when Time Machine is on, and they hold on to the space of files you've deleted.
• Cloud files you've opened. Once downloaded, they use local space in full until they're made online-only again.
• Big folders and apps you rarely open. Still yours and still wanted, just not needed on the internal disk every day.

Buying a Mac with more storage is one answer, but on Apple silicon you can't add internal storage later. How to manage your Mac, cloud and drives as one walks through the alternatives.

What does one-tap Run Tuhi actually do?

Run Tuhi is Storage Studio's one-tap clean-up. Tap it on Home and it works through a fixed set of steps, with live progress, then stops. It:

• clears caches and other clutter that apps rebuild by themselves,
• reclaims old local snapshots your Mac is holding on to,
• moves large folders that your rules match to your fast external drive, leaving a link behind so they still open from the same place,
• and can keep downloaded cloud files online-only while they stay safe in the cloud.

Anything that needs a decision from you, such as which app to move or offload, appears as a suggestion instead of being done for you. You can close the window and the run carries on in the background. Is Run Tuhi safe?

How do you free up space without risking your files?

The test of a one-tap tool is what it leaves out. Run Tuhi never empties the Trash, whatever your settings say, because that's the one step that destroys your own files for good. It doesn't delete your documents to make room. If you want a stricter rule still, the Never delete personal files — only move them switch in Preferences → Rules → Global overrides makes sure your files are only ever moved.

It's worth being straight about undo, too. Cleared caches aren't kept, because there's nothing worth keeping: the app recreates them, and the only cost is a slower first launch. Moves to your fast drive are reversible with Move back. Other clear-ups, such as temporary folders an app left behind, go to the Recycle Vault so you can restore them. Can a cache clean-up be undone?

Try Run Tuhi on your MacFree trial. For Apple silicon Macs on macOS 13 or later.

When should you use something more hands-on?

• You want to approve every step. The Free Up Space wizard previews each item first and lets you untick anything.
• You're nearly out of room right now. Emergency Space asks how much you need and builds the smallest, safest plan to get there, cheapest first. What Emergency Space does.
• You want to know where the space went. What's Using Space shows your largest folders first, and what grew recently.
• A big app you rarely open. In the Apps window, Offload archives an app and its data on your fast drive, and Restore brings both back. Move or offload?

Frequently asked questions

Does Run Tuhi delete my files?

No. It only takes steps that are rebuildable or reversible, and it never empties the Trash.

Does it work without the external drive?

Partly. Clearing caches, releasing space held in local snapshots and making cloud files online-only all work without it. Moving folders needs the drive connected. More detail.

Why do caches come back?

Because apps refill them as you use them, which is exactly what makes them safe to clear. Clearing caches is regular upkeep, not a one-off fix. Why caches fill up again.

The point isn't to be aggressive with your files. It's to give back the space you already own, safely. More guides: Free up space in the wiki.
