Troubleshoot Lite Sync plugin error on macOS

This guide explains how to fix an "Unable to start Lite Sync plugin" error with the kDrive application on macOS.

The Lite Sync extension does not have the necessary permissions.

Check the presence of the extension

From a Terminal:

% systemextensionsctl list

The result looks like:

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 output does not mention "kDrive LiteSync Extension", the extension is not present:

• remove sync and add it again

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

• allow the extension in System Settings / Privacy and Security

Check extension permissions

In System Settings / Privacy and Security / Full Disk Access :

Check the operation of the extension

From a Terminal:

% ps -ef | grep LiteSyncExt

The result looks like:

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 seem to be working, try the following actions:

• restart the app
• reboot the Mac
• remove / add sync
• uninstall / reinstall the app

 
If it's still not OK:

• request logs (Debug level)
• see in the Console if there is a blocking report on the date of the last start of the app and if so, send it to us

Retrieve kDrive messages in the Console:

• quit the app
• in the Console, select the Mac, filter on “[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 us
