Why won't the 1TB HD accept OS 10.12 Sierra?
How do I reformat the SSD to a GUID Partition Table Scheme when it's not a option in the Disk Utility?
Is this a good question?
you need to boot into recovery mode and use disk utility there.
you cant use the erase function, you need to use the partition function and change it to 1 partition mode and click the options button and choose GUID
