Does anyone else have this problem? It started happening for me as of 10.12.2. It used to be that when you have a file (e.g. a JPG) open in Preview, you could click on the file name in the window header and edit the file name. But now, if you try this and close the file or quit Preview, it no longer works. Previously, the file would've been renamed accordingly, but currently, the file name never gets updated. I already filed a bug report with Apple back in 10.12.2 but it's not fixed yet. Is anyone else having this problem or have a workaround?
