Hi all, I hope someone can help me with this problem (I have asked on the Adobe forum and someone suggested trying here). I am running Mac High Sierra and after a Photoshop CC 2018 update all my file icons look like this (the system generated icon previews of the document work fine, this is just the default icon): I have tried uninstalling and re-installing Photoshop but the icons refuse to change (Illustrator .eps look the same as well). I have tried changing the open with to 'preview' but the icon stays the same so have changed it back to photoshop. Your help would be very much appreciated. Thanks, Paul. --- Post Merged, Nov 13, 2017 --- I may have posted this in the wrong place and am more than happy for a moderator to move it. Thanks, Paul.
