Replacing HD with SSD in iMac

I'm having trouble replacing my original system hard drive with an SSD in my mid-2011 iMac (specs below).   Generally speaking, the issue is that after copying the system drive to the SSD, I can boot from the SSD, login and use the iMac as expected as long as the SSD is in an external drive bay attached by USB.  If I move the SSD to the internal drive bay, quirky things happen as described below.

THE SYSTEM:

mid-2011 iMac 21.5", 1TB HD, 8GB RAM

OS/X 10.12 (Sierra)

New SSD: Samsung EVO 850 500GB

Full Time Machine backup on remote NAS

I've tried restoring to SSD from Time Machine and I've tried cloning the system drive using Clonezilla.   Either way, the same thing happens if I replace the HD with the SSD.   Below are some of the things I've tried.   It looks like a permissions problem, but the permissions don't look off to me (and if they were, why does it boot/run when attached vis USB?)

SETUP 1

• System HD in interior drive bay
• SSD in external USB
• Restore SSD from Time Machine
• System booted from SSD

RESULT 1

• System boots normally
• Login successful
• Applications seem to work as expected
• Photoshop CC loads in about 4 seconds
• Adobe Bridge CC loads in about 3 seconds
• InDesign CC loads in about 5 seconds
• System Information shows SATA/SATA Express drive to be the internal HD
  • link speed: 6GB
  • Negotiated speed: 3GB
• From Terminal
  • diskutil list shows internal HD as disk0 and SSD as disk1.  SSD is system disk, mounted at "/"
    • /dev/disk0 to be the internal HD
    • /dev/disk1 to be the SSD
  • mount shows
    • /dev/disk1s2 on / (hfs, local, journaled)
    • /dev/disk0s1 on /Volumes/Macintosh HD 1 (hfs, local, journaled)

SETUP 2

• Same as SETUP 1, except HD has been removed from internal drive bay.

RESULT 2

• The results under this test condition are the same as for SETUP 1 except for any reverence to the internal drive is gone.
• System boots normally
• Login successful
• Applications seem to work as expected
• Photoshop CC loads in about 4 seconds
• Adobe Bridge CC loads in about 3 seconds
• InDesign CC loads in about 5 seconds
• System Information shows SATA/SATA Express drive to be the internal HD
  • link speed: 6GB
  • Negotiated speed: 3GB
• From Terminal
  • diskutil list shows
    • /dev/disk0 to be the internal HD
    • /dev/disk1 to be the SSD
  • mount shows
    • /dev/disk1s2 on / (hfs, local, journaled)
    • /dev/disk0s1 on /Volumes/Macintosh HD 1 (hfs, local, journaled)
• As expected, because there is no drive in the bay, there is no temperature sensing, so we have a case of “Drive Fans gone Wild!”

SETUP 3

• SSD installed in internal drive bay.

RESULT 3

• System boots normally
• Login goes as expected
• After a short period of time, the following message appears:
  • Keychain “login” cannot be found [Cancel] [Reset to Defaults]
  • I chose [Cancel] so as not to change anything.
• Fire up iTunes. The following message is displayed

“The folder “iTunes” cannot be found or created, and is required.

The default location for this folder is inside the “Music” folder.”

• It then prompts me to either choose a folder or create one.   I choose to create one in /Macintosh HD/Users/<my account name>/Music.  To which it responds:
  
  “The folder ‘iTunes’ could not be created. Please create a different folder.”
  
  Permissions on the”Music” folder are Read/Write for my account.
• Fire up Safari
  • Loads instantly
  • Go to Google.com
  • Safari displays:

Safari Can’t Open the Page

Safari can’t open the page https://www.google.com./?client=safari&Channel=mac_bm.
The error is: “The certificate for this server is invalid.  You might be connecting to a server that is pretending to be www.google.com which could put your confidential information at risk.” (NSURLErrorDomain:-1202)

• Open Spotlight (Command-Space) and type “Terminal”
  • Application “Dictionary” can’t be opened
• Launch “Terminal” from the Application menu
  • diskutil list
    • § /dev/disk0 shown to be the internally mounted SSD
  • mount
    • § /dev/disk0s2 on / (hfs, local, journaled)

Any ideas as to what is happening here?   If I remove the SSD and put it back in the USB dock, I can again use the system normally.

Thanks in advance for any insight you might be able to share.

A couple things that may or may not help.

With the SSD internal, do a PRAM reset, maybe even a

couple of times to be sure.  Reseting the PRAM will force

reload the systems hardware configuration.
(macOS Sierra: Reset your computer’s NVRAM or PRAM)

Actually, should do this anytime when you do any internal

hardware changes.

The other thing, with the SSD internal, reboot to its Recovery

volume.  Open Disk Utility in it and run Disk First Aid on both

the drive itself and on any volumes on the drive.
