This guide explains how to resolve certain Lite Sync macOS errors that may occur with the desktop app kDrive (desktop application on macOS).

Synchronization block 1/10

Check that macOS permissions are enabled for kDrive and the Lite Sync extensions:

1. Open the macOS settings:
   
2. Under General, click on Open and extensions:
   
3. Scroll down to the Endpoint Security Extensions :: kDrive LiteSync Extension indication:
   
4. Make sure the permissions are enabled and confirm at the bottom:
   

Take this opportunity to check the other elements related to kDrive to ensure everything is activated.

Error of type "Unable to start Lite Sync plugin"

To correct an error of type "Unable to start Lite Sync plugin" which usually occurs when the Lite Sync extension has disappeared or does not have the necessary permissions…

... check for the presence of the extension

From a terminal application (command line interface, CLI) on a macOS device:

% systemextensionsctl list

The result looks like this:

1 extension(s)
--- com.apple.system_extension.endpoint_security
enabled active teamID bundleID (version) name [state]
* * 864VDCS2QY com.infomaniak.drive.desktopclient.LiteSyncExt (3.5.0/1) kDrive LiteSync Extension [activated enabled]

If the command result does not mention "kDrive LiteSync Extension", the extension is not present:

• Delete the synchronization and add it again.

If the command result does not have the status [activated enabled]:

• Enable the extension in the System Settings / Privacy & Security.

... check the extension's permissions

In the System Settings / Privacy & Security / Full Disk Access of the macOS device:

... check the extension's operation

From a Terminal:

% ps -ef | grep LiteSyncExt

The result is similar to:

0  7434     1   0  1:02   ??         0:25.42 /Library/SystemExtensions/6035BDE4-B7D6-477E-A6AB-C2281E3C7752/com.infomaniak.drive.desktopclient.LiteSyncExt.systemextension/Contents/MacOS/com.infomaniak.drive.desktopclient.LiteSyncExt

If the extension does not appear to be working, try the following actions:

• Restart the app.
• Restart the Mac.
• Remove / add the sync.
• Uninstall / reinstall the app.

If that still doesn't work

• Request the kDrive logs (Debug level):
  
• Check in the Console if there is a blockage report on the date of the last app startup and if so, send them to Infomaniak:
  

Retrieve the kDrive messages in the Console:

• Quit the app.
• In the Console, select the Mac, filter by [KD], click on Start:
  
• Launch the app.
• Click in the list of messages, select them (Ctrl+A), copy them (Ctrl+C) and send them to Infomaniak.
