diskutil "eraseDisk" on disk0 using terminal
Hi Apple Team & Everyone, Can someone guide me why sending 'diskutil eraseDisk APFS "WIPED" GPT /dev/disk0' command via terminal to remove/wipe the main physical drive (disk0) is failed? I tried booting into recovery mode, but it still didn’t work. The command returned the following error: Started erase on disk0 Unmounting disk The volume on disk0 couldn't be unmounted because it is in use by process 0 (kernel). Error: -69877: Couldn't open device I understand that we can use Disk Utility (GUI) to unmount and erase the drive. Is it possible to perform this operation via Terminal to erase disk0? I would appreciate any guidance on this. Regards, Winson

Detection of Sync Drives such as OneDrive, DropBox etc.
I'm working on a cross-platform application that needs to access file attributes, specifically for files and directories in sync drives like OneDrive. On Windows, I use the GetFileInformationByHandle API to retrieve attributes such as FILE_ATTRIBUTE_RECALL_ON_DATA_ACCESS and FILE_ATTRIBUTE_RECALL_ON_OPEN to identify files that are stored remotely or in the cloud. Is there an equivalent API or mechanism on macOS to achieve the same? Specifically, I’m looking for a way to: Identify attributes similar to cloud/offline storage status for files in synced drives (e.g., OneDrive, iCloud Drive). Retrieve metadata to distinguish files/folders stored locally versus those stored remotely and downloaded on access. If there’s a preferred macOS framework (like Core Services or FileManager in Swift) for such operations, examples would be greatly appreciated!
