Apache can't access directories on USB drives on 10.15+ (Catalina)
On MacOS 10.15 or higher, it seems Apache cannot access directories on volumes that are considered "removable". All USB volumes seem to be considered "removable", so Apache cannot serve directories on USB drives.
Providing Apache with "Full Disk Access" does not fix this problem.
I have been able to work around it by installing SoftRAID and making the USB volume a SoftRAID volume (which somehow marks it as NOT removable)
Is there another way to change the status of a volume so that the system does not consider it "removable"?
