I'm new to MC on Mac and I'm new to version 23 as well, but there are two things that I believe must be some small bugs.
For me, at least, MC will sometimes freeze. I can't say that I have noticed any pattern here, but being in the middle of copying my files from PC to Mac, there ARE at times quite a lot of files for MC to handle, but I don't know if there is any connection.
Also, in this process I have been going through the Rename, Copy, Move function quite a lot of times. What happens almost every time, is that I can't access the OK, Cancel and Help buttons in the bottom right corner, without expanding and minimizing the window (green dot) several times. The three buttons simply don't pop up, that is. The expand/minimize process sometimes has to be repeated 10-15 times, and gets a bit frustrating.
Apart from that, everything seems to work fine, though.
If this is NOT related to bugs, please let me know a solution.
