How do I set up Qsync on a Mac and verify the correct folders are synchronising?

Applies to: Qsync for macOS with a supported QNAP NAS. Current Qsync Client6 layouts/features differ from the historical client illustrated in older versions of this guide.

Work through these checks

1. Check the supported combination. Record macOS, Qsync Client and Qsync Central versions. Obtain the supported client for the Mac and verify the NAS application is running.
2. Enable the intended NAS folder. Have the administrator confirm the user's application/shared-folder permissions and that the intended shared folder is available for Qsync. Do not enable unrelated shares merely to simplify discovery.
3. Connect the correct NAS account. Use the intended secure address and authorised account. Check the certificate/connection result and confirm this is the correct NAS before choosing a folder pair.
4. Review the folder pair and direction. Choose one clearly labelled local folder and its intended NAS destination. Read the sync direction, filtering, space-saving and deletion behaviour before accepting the pair.
5. Test both required directions. Keep a separate backup and use harmless test files. Check what happens after a local edit and a NAS-side edit according to the chosen sync mode.
6. Check history before changing the task. If a file is missing or returns after deletion, review filters, logs, permissions and the version history. Preserve unsynced work before recreating a task.

Confirm the result

The expected files appear at the correct destination and their content matches. A Connected or Up to date label alone is not a complete file check.

If you need help

Include these details in your ticket: macOS/client/server versions, sync direction, folder-pair layout and one anonymised missing-file example.
