external USB HDD on iMac



Not having enough space on my Macintosh HD I ordered a WD 2To

All kodi I tested are hable to find my files on the inside mac HDD
but impossible to read the external HDD
I changed partition doesn’t seems to come from there
I always give permissions to the disk but nothing

I  am using Kodi since years with synologu NAS but for a few month I wanted to ise it only on my computer

Please I need help I tested every thing I could think about
