Question: osx sierra. How can I format to Mac OS Extended Journaled?
I am trying to format my SSD with High Sierra on my Macbook Pro i7.
When I erase in Disk Utility, it erases to APFS and not Mac OS Extended Journaled.
It won't complete installing OS X. The message keeps appearing that says,
"Could not create a preboot volume for APFS install."
Can someone please help?
Thanks in advance,
Mac Pro, OS X El Capitan (10.11.1), 8 CORE/24GB RAM/4TB HD/Dual Monitor
