Box Sync
Box Sync is a macOS desktop app that mirrors selected Box cloud files to your Mac for offline access and automatic syncing.
What is Box Sync?
Box Sync is a cloud storage and file synchronization app for macOS that connects your Box account to your desktop. It lets you work with Box files in Finder, keep selected content available offline, and automatically upload local changes back to Box when you reconnect. This workflow is useful for people who regularly edit documents, media, or project files outside a browser and want a familiar folder-based experience on their Mac. Box Sync creates a local Box Sync folder and keeps marked folders in step with your online account so you can move between desktop and web work more easily. Box has announced end of life for Box Sync in December 2026, and the company recommends moving to Box Drive for ongoing desktop access.

Safety overview
Status: Mostly safe
Box Sync is legitimate Box software for syncing cloud files to your Mac. It needs access to files you choose to sync and may run in the background so changes can upload and download automatically, which is normal for this kind of app. The main practical concern is product lifecycle: Box has announced end of life for Box Sync in December 2026, so long-term use is not ideal. If you still rely on it, keep important files backed up and plan a move to Box Drive.
Recommendation: Keep Box Sync only if you still actively use it with a Box account and need its local sync workflow. If you no longer use Box or have already moved to Box Drive, you can remove it. If you depend on it for ongoing work, start planning a transition before support ends so your file access stays smooth.
