I have the latest version of PS 21.2.1. I watched a tutorial on the newest version of the selection tool. It worked beautifully. I downloaded the exact image the youtuber was using. When I used the selection tool it selection was inferior to what the youtuber was getting. I did exactly what he was doing, on the exact image. He was comparing 2019 PS to 2020 PS. My results did not change. The selection looked like the 2019 version. I am on a older Mac laptop.16 gigs of ram. The sample image is only 8 megs.I can't figure out why my results are not the same. Any help in this regard would be greatly appreciated.
