v1.3.0
Disk list that keeps up- The Select a Disk window now updates on its own when you mount, eject or rename a volume (#12). Network shares, external drives and disk images appear without restarting OpenDisk.
Changelog
What's new in OpenDisk.
OpenDisk checks for updates automatically via Sparkle. Install once and it will offer each new version when it ships. You can also download the latest release directly.
v1.2.9
Breadcrumbs, shortcuts and a full-disk refresh- Breadcrumbs at the top of the window now respond to clicks on macOS 15 Sequoia (#8). Long paths collapse the middle folders instead of scrolling sideways.
- Keyboard shortcuts for moving through the list, opening folders, Quick Look, Show in Finder and adding items to the Collector. Change any of them in Settings.
- Refresh now returns to the top level and rescans the whole disk.
- A new setting in Settings > Chart turns off the free space wedge, so scanned folders fill the chart on large, mostly empty drives.
v1.2.8
Version 1.2.8- Free space is now shown as a gray wedge on the sunburst when viewing the whole disk, with used and free sizes in the center (#11)
v1.2.7
Clickable breadcrumbs on macOS 15- The path items at the top of the window are clickable again on macOS 15 Sequoia. Click any earlier folder in the path to jump back to it.
- A new Enclosing Folder button in the toolbar, and the Finder shortcut ⌘↑, take you up one level.
v1.2.6
Free space that stays up to date- The available space in the status bar now updates on its own every couple of seconds. Before, it was read once when a scan finished, so it could show an old number after you deleted files or emptied the Trash.
- Available space now includes purgeable space, the same way Finder counts it. Hover over the readout to see how much of it is purgeable.
- Reopening a location you have scanned before uses the saved scan more often instead of starting over, so large disks come back faster.
v1.2.5
Drag files into Finder and other apps- Dragging files and folders out of OpenDisk now hands other apps the real items, so you can drop them into Finder, Dropover, VS Code and more. Previously some apps received a .json file instead.
- Select several rows and drag them together. In Finder a plain drag moves the items like a normal Finder drag; hold Option to copy.
- Items in the Collector can be dragged back out: drop one anywhere outside the Collector to remove it from the list. Nothing is deleted, and Undo Collect brings it back.
- The scanner's worker threads no longer sit blocked while waiting for work, so macOS can schedule them at the right priority.
v1.2.4
Full Disk Access fix for macOS 27- Fixed Full Disk Access not appearing in System Settings > Privacy & Security on macOS 27.
- OpenDisk now detects when Gatekeeper runs it from a temporary location and relaunches itself, so the permission request registers correctly.
v1.2.3
Full Disk Access on macOS 27- OpenDisk now reliably shows up in System Settings > Privacy & Security > Full Disk Access on macOS 27, so the permission can be granted right after the first launch.
- Opening the Full Disk Access settings from OpenDisk now registers the app in the list first, so it is always there when the pane opens.
v1.2.2
Version 1.2.2- Hard-linked files are counted once after a quick rescan
- HFS+ drives now use the same scanner as APFS, fixing oversized totals and enabling fast rescans
- Clearer wording in a few messages
v1.2.1
macOS 15 support & disk capacity at a glance- OpenDisk now runs on macOS 15 Sequoia. On macOS 26 it keeps its Liquid Glass panels; on Sequoia they use the system's standard translucent material.
- The status bar now shows how full the disk is: a capacity bar with “X available of Y”, and hovering it reveals the used, available and total figures. It refreshes after every scan, so freed space shows up right away.
- Leaving a scan is now explicit: an Unmount button in the toolbar (⌘[) asks before clearing the scan and returning to the disk list. It does not eject the disk from macOS.
v1.2.0
Quick Look previews & faster rescans- Quick Look previews, just like Finder: select any file and press Space, or right-click and choose Quick Look. Arrow keys step through the list while the preview is open.
- Rescans start much faster: checking what changed since the last scan now runs concurrently with loading the previous results, and gives up early when a full scan would be quicker.
- The status bar now says what the scan is actually doing instead of sitting on a bare “Scanning…”.
- Clicking a file now selects it, so you can see what Space will preview.
v1.0.1
Install polish- OpenDisk now offers to move itself into the Applications folder on first launch, so automatic updates always work.
- Tiny download for existing users: this update ships as a 133 KB delta.
v1.0.0
Initial release- Interactive sunburst chart: hover any slice for its exact size, click to zoom into that folder.
- Full-disk scans in seconds: results stream in live while the scan runs.
- Incremental rescans reuse the previous scan and replay filesystem events, 20–28× faster than a cold scan.
- Sortable, Finder-style folder list with breadcrumbs beside the chart.
- Understands APFS volume groups, firmlinks, purgeable space, and system volumes.
- External drives appear automatically when connected.
- Automatic updates via Sparkle.
