Solution

As detailed in our supported platforms, the 2020 CSD System software is currently only supported on macOS 10.13, 10.14 and 10.15.

Apple has recently released a beta version of its next version of macOS, version 11 (Big Sur). The 2020 CSD System is not currently compatible with Big Sur, so we would not recommend that our users update to either the beta version of Big Sur, or the final release version, until we have released a version of the CSD-System which is compatible. The list of supported platforms that we have tested work with our software is detailed in the release notes that accompany each release.
