I'm trying to format a 32gb flash drive to APFS and am unable to. I'm using Terminal and the 'diskutil' command Code: diskutil apfs createContainer /dev/disk2s1 and it returns Code: Started APFS operation on disk2s1 NO NAME Creating a new empty APFS Container Error: -69773: A GUID Partition Table (GPT) partitioning scheme is required This is probably related to the fact that this flash drive was originally formatted (by fdisk) in FAT32 format: Code: /dev/disk2 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *30.8 GB disk2 1: Apple_HFS NO NAME 30.8 GB disk2s1 From what I can determine, I need to get rid of 'fdisk' partition scheme container before I can proceed. Yes ? The 'gpt' commands I've tried just give me 'permission denied' errors. How do I do this ?
