Macports , which was used to build the digiKam PKG, has a rolling release policy making it difficult to provide binary compatibility with older versions of macOS. Macports packages are frequently updated for security reasons, and this can require a more recent macOS SDK.

If you update digiKam to a new major version, for example from version 7 to version 8, we recommend you first backup your database files, since the internal schema may have changed. Typically, digiKam is able to migrate tables from an older version to a new one, and all of this is done automatically at startup. But it’s always better to save these important digiKam files before upgrading the application. See the Database Backup section in this manual for more recommendations.
If you use a bundle such as the official Linux AppImage, macOS package, or Windows installer, the application can be updated using the Help ‣ Check For New Version menu entry. See the updates settings on the Behavior page of the configuration dialog.
