Bootable Startup Drive Problem
How do I create an HFS bootable startup drive for Intel?
Here are my steps on an Intel iMac running Big Sur:
- Format an external HDD as Mac OS Extended (Journaled) using GUID Partition Map.
- Tell Install Disk Creator (or Terminal) to make this drive a bootable Mojave startup drive.
- Success!
Except… Install Disk Creator and Terminal both insist on reformatting the target drive as APFS.
Problem: APFS is designed for SSDs. It will thrash-and-trash HDDs.
Is there no way to create an HFS bootable startup drive for Intel on Intel?
Thanks.
