Well, after 4 failed attempts to clone the old OSX HDD to the new 1TB seagate SSHD I finally got it to work using OSX‘s built in Disk Utility.

In the end user theratter gave me the answer

Clone El Capitan to a New Disk

  1. Restart the computer. Immediately after the chime hold down the Command–R keys until the Apple logo and progress bar appear.

  2. When the Utility Menu appears select Disk Utility and click on the Continue button.

  3. When Disk Utility loads select the disk (usually, the out-dented entry) from the side list.

  4. Click on the Partition tab in Disk Utility‘s main window. A panel will drop down.

  5. Set the partition scheme to GUID.

  6. Set the Format type to Mac OS Extended (Journaled.)

  7. Click on the Apply button, then click on the Done button when it activates.

  8. Select the new Seagate drive then select Restore from the Disk Utility’s Edit menu.

  9. From the dropdown menu select the volume you want to clone.

  10. Click on the Apply button to start the process.

 

After some struggle to remove the old drive the new drive works and after resetting the PRAM, the MackBooPro now boots super fast.

Thank you forum member theratter
