I've downloaded some gopro footage to my local hd and then copied the files from my hd to an external drive. Whenever I want to change the access rights it will switch back to read only in Nautilus. Likewise if I change the ones for the files below. How can I give full rights? I need to process the footage on a mac.

enter image description here

sudo parted -l /dev/sdb

Modell: JMicron Generic (scsi)
Festplatte  /dev/sdb:  500GB
Sektorgröße (logisch/physisch): 512B/512B
Partitionstabelle: msdos

Nummer  Anfang  Ende   Größe  Typ      Dateisystem  Flags

From this line
/dev/sdb1 on /media/nuc/500GB type fuseblk (rw,nosuid,nodev,allow_other,default_permissions,blksize=4096)
I see that external drive filesystem is NTFS and it was by default mounted without respect to NTFS permissions. In this case all files/directories will have the same permissions and attempts to change them will be ignored.

I have solved similar problem by making permanent share with explicit settings:
write line
UUID=C848-2413 /mnt/E_DRIVE vfat rw,user,exec,umask=002
into /etc/fstab where UUID is from sudo blkid. (Then mkdir /mnt/E_DRIVE, setting permissions, then umount / mount.)

Simpler alternative is to install special tool:
