I have just purchased a new iMac today, moving up from my late 2009 version.
Same actions I have always used transferred over no problem.
I went to image processor from bridge to run my action over all of my photos and got that error message. It didn’t do anything to the files. Jst opened them and sent the error. Nothing even showed up in the history.
It is brand new version 2018 Creative cloud photoshop.
What can I do to fix this ?
Please let us know the error code you got while running the action in Photoshop.
Also, have tried creating the same action in Photoshop CC 2018? and check if that helps.
