Is there a possibility to edit the following files in macOS 10.12 Sierra:
I want to change the following things of the Screenshot-Files:
- Date and time Format in file name (no, that could NOT be done via System Preferences!)
Previous naming scheme: Screenshot 20161004_162222.png
Naming scheme now: Screenshot 2017-08-07 um 17.02.08.png
I want to revert to the previous scheme.
My problem is, that I can edit both files, but only on the second I can also save them. BatChmod nor chmod in terminal can change permissions on first file
