I just tried creating a fresh wallet on OS X but it worked fine for me. Is there anything non-standard about your installation by any chance? Are you using command line arguments to start it? Could you start a terminal and enter
open /Applications/Electrum.app/Contents/MacOS/Electrum
And tell me if you get any errors or warnings if you try to add labels.
Just did. No errors or warnings. Just a blank console screen. Assuming I only need to hit enter while editing to save a label. open /Applications/Electrum.app/Contents/MacOS/Electrum
And tell me if you get any errors or warnings if you try to add labels.
