Direct Sync Imac To Macbook Not Working in Sync Troubleshooting Posted December 10, 2015 · Report reply Hi, I'm using Sync Pro on my iMac, Macbook and Syno DS211J on my home LAN. Both Macs are able to sync folders to the DS for backup. I now want to sync a folder directly from my iMac to the Macbook, but BTS is indicating No Peers. The iMac is connected by ethernet, the Macbook is WiFi. I have no idea why this doesn't work, I can access either device with Finder just fine. Your help appreciated. Thanks in advance.
