I have installed Photoshop 21.2.0...

On my iMac at Work the new improved "Select Subject" Algorithm is working perfectly!

Now I have tried it on my iMac at Home (its an not so powerful iMac), it seems it use the older Algorithm (with no better Selections (like hair etc.)... :-(

Whats happen here?

My iMac at Home is:
iMac Retina 4K, 21,5", Late 2015, High Sierra 10.13.6, 8GB RAM, Intel Iris Pro Graphics 6200

Hi Christian, MacOS.10.13.x macOS will run old (original) Select Subject model. New Select Subject models require macOS 10.15.x or 10.14.x.

I updated as well. When I use the new and improved select subject and move it to a new background, when I try to move the subject in the new background Photoshop makes another copy of the subject!

You have "Legacy Compositing" checked. Go to Preferences > Performance... and uncheck "Legacy Compositing"
