Thank you very much for testing and following up on this. Much appreciated. My Mac has the latest MacOS 15.3.2 and latest TT Premier. I noticed that TT saves the file without asking but not with every change. So, I kept open the Finder window while making changes in a couple of TT forms then after a while I noticed the Finder showing a current timestamp indicating it had just saved the file. It does not happen immediately after every change, but it seemed to save the file after a calculation resulted in new values in the Fed or State summary. Once this happens, the Revert Changes will no longer work.
