When saving files from Photoshop 2020, file permissions are not set correctly. They are usually set to 774, but are being set to 600. So, it sets the user to read/write, and no permissions for anyone else. This causes huge issues, as we have limited ability to change permissions on our Macs at work. Running Photoshop 21.0.1 on MacOS High Sierra (10.13.6) on a 2013 Mac Pro. This happens whether a file is saved to the desktop or our network. This was not an issue with Photoshop 2019.
