Replace original hard drive with a new SSD
I attempted to replace original hard drive with an SSD. The drive was reformatted, El Capitan was downloaded and all the files were transferred to the new drive. The new drive was then tested outside of the computer and the computer booted normally while the original drive was still in the computer. I replaced the original drive with the new SSD. Computer booted normally, but none of the applications work. They just do not open. So I took out the new SSD, left it outside and kept the original drive in the computer. Everything works fine. Computer boots off of the new SSD and all the applications work. Trying to see whether anyone has any clue as to why the new SSD could not work independently while in the computer. Thank you.
Is this a good question?
