FotoMagico 5 writing to Synology NAS

I have an iMac 2019 with BigSur 11.2.3. I have a Synology NAS 918+ with 7TB storage and 2 1TB Samsung Pro nvme for caching. I use PixelEyes AutoMounter to mount the NAS volumes via SMB. I have FotoMagico 5.6.14.

  1. With only FotoMagico, when I try to share to the NAS, I get the following error: “No Write Permission. You do not have permission to write to the temporary items folder of the volume “Macintosh HD”. Please choose a different volume”

Hoping someone can provide insight. I’m able to write to the NAS volumes with all other apps.

Regards,
Fred
