I am trying to convert to APFS my new Sandisk Extreme 900 but I can’t use the describe way in support. Th eoption to convert in UI is greyed:
and using the command line return :
○ → sudo diskutil apfs convert /dev/disk2s1 Password: Error starting conversion from HFS to APFS: A GUID Partition Table (GPT) partitioning scheme is required (-69773)
Partitionning is disabled in the UI, I guess it can be done in console, but is it safe? Did others tried it?
