If Finder does not show Sync icons for synced folders and/or the context menu lacks Sync option ("Sync to this device", "Remove from this device", etc), or the “Share folder with Resilio Sync...” option, try resetting Mac browser extension:
2.Relaunch Finder: press Alt + right click on Finder in Dock -> Relaunch or click on Apple -> Force Quit -> Finder.
3.Restart Sync. In Terminal verify if Finder extensions are enabled for Resilio Sync with command pluginkit -vmA | grep "com.resilio". In the output leading + means "enabled".
+ com.resilio.Sync.FinderExtension(1.0) D4DA5305-FAA7-46E5-9A48-8B9C52472AE5 2025-07-04 07:29:05 +0000 /Applications/Resilio Sync.app/Contents/PlugIns/FinderExtension.appex
3. If that didn't help, enable Finder Extensions manually in Terminal by running these two commands
pluginkit -a "/Applications/Resilio Sync.app/Contents/PlugIns/FinderExtension.appex"
pluginkit -e use -i com.resilio.Sync.FinderExtension
Note that other applications (e.g., Dropbox, Google Drive, etc) use the same extensions, so if such apps work with the synced folders, there might be a conflict which may result in the absence of Sync icons as well as sync-related items in the contextual menu.
If you try the above steps but menus/icons keep disappearing, please contact Support. The Support team may ask for your system logs, so it's recommended that you prepare them in advance. To do so, go to Applications (shortly after you’ve spotted the issue) > Utilities > Console.
Copy-paste the log contents into a text file and save it. Collect debug logs from /Users/Username/Library/Application Support/Resilio Sync (sync.log and its zip archives) and send it to support (or attach it to the help request form.)

If the 32-bit (x86) version is used, there will be only one Sync extension - for x86.
