Just to clarify if it was not obvious: this is a NEW version of the OS (in beta) and I assume ccleaner will eventually support macOS but currently it does not - nothing surprising here. This kind of response involving a poor reading of the initial thread wastes time and effort. ccleaner version: 1.13.442 (latest) downloaded from pirform. OK but I DID say which version of the OS, it i called macOS (see my title).
