Cant ́t open PSD file saved on Mac OS Sierra 10.12.2

I updated yesterday new OS (Sierra 10.12.2) for my Mac Pro and also updated Photoshop and Lightroom to the newest versions. After that I realized I can ́t open any PSD-file I ́ve created with this updated OS. All earlier PSD documents open normally, but the ones I ́ve created after update will cause the message: "Could not complete your request because it is not a valid Photoshop document".
I tried to get back to older Photoshop 2015, but encountered the same problem. If I save a PSD file, can ́t open it again.I ́m screwed.

I copied one PSD-file saved on Sierra system to my another mac (running El Capitan and Photoshop 2015) and the problem exists: It can ́t open that file, same message. So it must be something on Saving process. I have checked the privileges .
