macOS 26
The Mac operating system release that Seven Hills apps require, and the home of Liquid Glass on the Mac.
macOS 26 is the version these apps are built for. It is the Mac release in the same generation as Apple's Liquid Glass design. Seven Hills does not list support for older macOS versions on this site, because that support is not part of the product description.
Disk Housekeeper, Murmur, and Cairn are native apps on this release. They use Liquid Glass rather than a custom theme. Hardware requirements beyond the operating system are not stated here, so this page will not invent a chip or a memory floor.
