Kodi 17 Cant Find My Mac On the Network

I had Kodibuntu installed on my Intel Nuc running Kodi 14 and it connects to my iMac running Sierra fine via SMB, but when I update to Kodi 17 it can no longer find my imac. This happened when I tried to update from Kodi 16 to 16.1. I thought it was something to do with 16.1 and just reinstalled Kodibuntu and didn’t update it. Now that it doesn’t work with Kodi 17 something else must be the problem. I tried installing the newest Lubuntu and then Kodi 17 separately but still had the same issue. Any help on how to resolve this would be great. Thanks!
