OmniDiskSweeper for Mac Release Notes

OmniDiskSweeper 1.12 adds support for Catalina (macOS 10.15). (These builds require macOS 10.14 or later.)

Catalina Volume Layout — Like Finder, the drive list in OmniDiskSweeper will now present a consolidated view of Catalina’s read-only root and read-write data volumes. Scanning files on this volume will show files based on their location in the volume group (i.e. applications you install will appear in /Applications rather than /System/Volumes/Data/Applications) and will no longer show an additional copy from the data volume’s mount point (which shares its inode device with the root volume).
Catalina Notifications Alert — Earlier builds of OmniDiskSweeper had some unused software update logic to present a system notification when a new build was available. While this code wasn’t ever actually presenting any notifications, its presence was triggering a prompt on Catalina asking whether to allow notifications from OmniDiskSweeper or not. You could safely answer “Don’t Allow” in earlier builds, but we’ve now removed this unused logic so you won’t have to worry about this decision any more.
Dark Mode About Panel — Updated the About Panel to use appropriate colors in Dark Mode.

Dark Mode — Added support for Mojave’s Dark Mode.
File Access Alerts — On Mojave, any app which attempts to access a folder which contains your calendars, contacts, photo library, or reminders will trigger an alert. When OmniDiskSweeper scans the files in your home folder, it triggers these alerts: so we’ve added a description that explains that OmniDiskSweeper doesn’t actually open any of the files it scans, it just lists those files for you to review. If you wish, you can avoid these prompts by granting OmniDiskSweeper full disk access under System Preferences > Security & Privacy > Privacy. (Or you can proceed without granting OmniDiskSweeper permission to scan those folders, in which case OmniDiskSweeper won’t be able to tell you how large they are.)
