プロジェクトの歴史

Howard Oakley introduced a test build of Cirrus in March 2018 to extract and present iCloud-related unified-log entries and perform a controlled upload test. Version 1.0 followed in May 2018 with browsing, eviction, status inspection, and detailed reporting.

Development continued as Apple changed iCloud Drive internals and macOS. Later releases restored compatibility after path changes, added broader diagnostic capabilities, became universal applications, and refreshed the interface for newer macOS releases.

採用の歴史

Cirrus occupies a specialist role in the macOS utility ecosystem because macOS offers few user-facing tools for diagnosing iCloud Drive synchronization. The author distributes it as freeware alongside related Mac diagnostic utilities.

Successive releases adapted its browser and log tools to changes in macOS and iCloud Drive, including Catalina path changes, Apple Silicon, Sonoma logging, and Tahoe interface conventions.

使われ方

Users can inspect detailed iCloud file and folder state, download or evict local copies, perform a controlled test upload, and review filtered iCloud-related log activity.

The log browser requires an administrator account. Cirrus's test creates a temporary one-megabyte file in local preferences and iCloud Drive and provides a cleanup command afterward.

パッケージ好きにとっての重要性

Cirrus exposes iCloud Drive state that is otherwise difficult to inspect, combining file download and eviction controls, a custom browser, a repeatable synchronization test, and filtered unified-log access.

For administrators and advanced Mac users, it provides a graphical complement to Finder and the sparsely documented brctl command.
