Is Unity Hub Cache Safe to Delete?
Yes. Unity Hub's Cache folder stores downloaded editor installers and thumbnails.
Side effects: Unity Hub may re-download installer metadata on next use.
What is ~/Library/Application Support/UnityHub/Cache?
Unity Hub caches downloaded Unity Editor versions and related assets. Your actual Unity projects are separate. Safe to delete — Hub re-fetches what it needs.
Is it safe to delete?
Yes — ~/Library/Application Support/UnityHub/Cache is generally safe to delete. The data in this folder is temporary and will be recreated by the application when needed.
Before deleting, make sure:
- You don't have any important unsaved work in the related application
- You're not in the middle of a critical task that might need this cached data
- You understand that initial load times may be slower after deletion
What happens after deletion?
Unity Hub may re-download installer metadata on next use. The folder will be recreated automatically by the application when needed. This process is typically seamless but may take some time depending on the amount of data that needs to be regenerated.
