Mount NFS on mac 1. Open Terminal. 2. Run: sudo mkdir -p /System/Volumes/Data/Users/Shared/Movies0 3. Run: sudo chown $(whoami) /System/Volumes/Data/Users/Shared/Movies0 4. Test manual mount: sudo mount -t nfs -o resvport 192.168.1.156:/volume1/Movies0 /System/Volumes/Data/Users/Shared/Movies0 5. Run: sudo nano /etc/auto_master 6. Add this line at the end: /- auto_nfs -nobrowse,nosuid 7. Save and exit (Control O, Enter, Control X) 8. Run: sudo nano /etc/auto_nfs 9. Add this line: /Users/Shared/Movies0 -fstype=nfs,-P 192.168.1.156:/volume1/Movies0 10. Save and exit 11.

Note: When added a new Shared Folder on NAS and mounting with NFS: 1. Configure NFS permissions 2. Mount 3. Restart radarr container 4. Add new folder in radarr Otherwise, the downloads will be moved to a 'phantom' folder that's only present on the system with radarr, it will not be moved to the NFS mount and will not even be visible until the Mount is unmounted.
2026 Troubleshooting: had to edit auto_master and auto_nfs: added this line to the end of auto_master (which seems to have disappeared after a mac update?) /- auto_nfs -nobrowse,nosuid Then I had to change the formatting of the auto_nfs to be exactly this: /Users/Shared/PlexMedia -fstype=nfs,resvport 192.168.1.156:/volume4/Movies /Users/Shared/TV0 -fstype=nfs,resvport 192.168.1.156:/volume2/TV0 /Users/Shared/TV3 -fstype=nfs,resvport 192.168.1.156:/volume3/TV3 /Users/Shared/Movies0 -fstype=nfs,resvport 192.168.1.156:/volume2/Movies0 The primary issue was the server was connecting over wifi instead of ethernet, which led to slow/unstable remote playback. turning off wifi and turning of "auto connect" to the specific wifi network should prevent that in the future (since mac keeps turning wifi back on after reboot). Updating the OS seemed to have removed the line of text at the end of auto_master? which caused none of the NFS volumes to mount on reboot. or perhaps the formatting of the auto_nfs suddenly needed to change?
