A note on iCloud based Sync

\n

The older iCloud based syncing method has been deprecated on Arc for macOS as of version 1.48.0 released on June 20, 2024 and has been replaced with end-to-end encrypted Arc Sync.

Arc for Windows and Arc Search for iOS only support end-to-end encrypted Arc Sync.

Please update your version of Arc for macOS to use the new end-to-end encrypted sync by following these steps.
