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?

Re: convert to APFS?

You need to change the drive to a GUID partition scheme. The knowledgebase article below should help.
