DaisyDisk 4.34.2 — macOS

People who run out of disk space and want to know exactly what is taking it up use DaisyDisk. Office workers, designers, video editors — anyone with a Mac who needs a clear picture of storage without hunting through Finder folders. The app scans any mounted disk and draws an interactive map that shows every file and folder proportional to its size. Large files are obvious at a glance, and the "Other" category gets broken down so you are not guessing what is in there.

You can preview files with Quick Look or delete them straight from the map by dragging them to a trash area. The current version adds support for APFS clones: it counts only the first occurrence of each clone, so the numbers reflect real used space, not duplicated snapshots. The fix also improves accuracy on FAT32 and exFAT volumes, and corrects a scanning bug that affected systems before macOS 14 Sonoma.

DaisyDisk works on any Mac from macOS 10.13 High Sierra up through current releases, Intel and Apple Silicon both supported. The interface is available in English, German, Spanish, French, Japanese, and several other languages. It is a straightforward utility for anyone who wants to keep a Mac healthy without guesswork.

Scans multiple mounted disks at once

DaisyDisk does not overload you with options, but a few details in the interface make daily use simpler than you might expect.

The app can scan multiple mounted disks at the same time. If you have an external drive or a network volume connected alongside your internal drive, you can start a scan on each one without waiting for the first to finish. This saves time when you are checking storage across several volumes.

Real-time information about mounted disks appears as soon as you open the window. You see each drive listed with its total size and free space before you run a scan. That alone can answer a quick question: is there room to copy a project over, or is that external drive nearly full? No scan needed.

The visual map itself is interactive in a way that feels natural. Hover over any block, and the file or folder name shows up. Click once, and the map centers on that area, expanding it so you can see what is inside. This works the same way whether you are looking at a folder full of project files or a single large archive. You never have to dig through a tree view if you prefer the map.

For anyone who keeps a clean system, the drag-and-drop delete area is placed consistently at the bottom of the map window. You can add files to it one at a time or drag a whole folder. The app asks for confirmation, and that is it. No secondary window, no extra steps.

Handles APFS clones from Time Machine and Docker

Version 4.34, released in mid-2026, added support for APFS clones. If you use a modern Mac with APFS-formatted storage and take advantage of file cloning — common with Time Machine snapshots, Docker containers, or certain backup tools — you have probably seen disk usage numbers that did not add up. DaisyDisk now counts only the first occurrence of each clone. The result is a space calculation that matches what the file system actually consumes, not the sum of every copy. For someone managing a system with frequent snapshots, this correction makes the scan report useful again.

The same update improved how the app estimates hidden space. That is the space the operating system reserves for itself or for metadata. It is not usually visible in Finder, and earlier versions of DaisyDisk could overstate how much was truly unreachable. That estimate is now more accurate, which matters when you are trying to free the last few gigabytes on a nearly full drive.

Version 4.34.1 fixed a scanning bug that affected macOS versions before Sonoma. If you are running macOS 13 Ventura or earlier and found that scans would hang or return incomplete results, that bug is resolved. Version 4.34.2 is a small follow-up that fixes a separate bug introduced in 4.34.1. The current version is stable for all supported systems.

For users on macOS Tahoe, version 4.33.2 improved compatibility and hidden space estimation accuracy. And if you use external drives formatted as FAT32 or exFAT — common for USB sticks or drives shared with Windows machines — that same release fixed a wrong size estimation that could make files appear larger than they really were. That correction carries through to the current version.

Lets you preview files with Quick Look

DaisyDisk does not require any companion software, but it plays well with several macOS tools you probably already use.

Quick Look integration means you can preview a file directly from the map. Highlight any media file, document, or archive, and press the space bar to see what it contains before you decide whether to delete it. This is the same Quick Look that works in Finder, and DaisyDisk triggers it without extra configuration.

Because the app works with mounted disks, it respects whatever you have connected through macOS. You can scan an external USB drive, a Time Machine backup volume, or a network share mounted through the Finder. The scan treats them the same way it treats your internal SSD. No special setup required.

Drag-and-drop deletion sends files to the Trash. That means you can recover them from the Trash later if you delete something by accident. DaisyDisk does not bypass the standard macOS safety net. If you prefer a different workflow, you can use the app to locate files and then remove them manually in Finder or Terminal. The map gives you the location, so you are not left guessing.

The interface supports Retina displays, so text and map details stay sharp on high-resolution screens. That is a small thing, but it matters if you work on a recent MacBook Pro or an iMac with a 4K or 5K panel.

Reveals what hides in that shared iMac's 'Other' category

Consider a shared iMac in a small office that several people use for design, spreadsheets, and file storage. Finder shows a large "Other" category, but nobody knows what is in it.

You open DaisyDisk from the Applications folder and start a scan of the main drive. Within a minute, the map shows the largest blocks. One of them is a folder full of client project files from a designer who left the company. Another is a cache from a video editing app that nobody bothered to clear.

You select the virtual machine file on the map, preview it with Quick Look to confirm it is an old Windows VM that nobody uses, then drag it to the delete area. You repeat the process for the cache folder and the old project files. The office Mac has room to breathe again, and you did not need to guess which files were safe to remove.

That same scan works on an external drive if someone brings in a portable SSD full of project archives. DaisyDisk handles it the same way, and the parallel scan feature means you can check both the internal drive and the external drive in one session.
