How do I clone from a Mac OS Extended (Journaled) spinning hard drive to a new SSD on 10.13.6 I have a MacBook Pro (13-inch, Mid 2010) with a 500GB spinning hard disk boot drive with High Sierra 10.13.6. Disk Utility reports the drive as "SATA Internal Physical Volume - Mac OS Extended (Journaled)". I ran First Aid on it and it came back good.

I have a 500GB SSD in a USB enclosure.

I booted into Recovery and started Disk Utility. I erased the SSD and chose plain APFS format (the four options available are all APFS variations). I tried restoring to the SSD, but the Restore window shows "None Available" in the "Restore from:" drop-down.

I read something that suggested converting the boot disk to APFS, but that menu item is grayed out when I select that drive.

How can I get the contents of this spinning hard drive onto the SSD?
While the only format options available for the new drive were APFS variations, after formatting I was able to use the Partition tool in Disk Utility to morph the new drive into "Mac OS Extended (Journaled)". Once the format type matched between the two drives I was able to restore from the existing system drive onto the new SSD.
