Hi,
Since the very first beta (I am now on 10.13 Beta (17A306f)), I have had problems with "Trash". I have the beta installed on a 2013 Mac Pro, as well as a 2014 MacBook Pro, and they both experience the same problem. I did NOT select APFS on either machine. What happens is that I delete a file, and well nothing happens. The file is gone, but it is not moved to the trash can, and when I open the trash can, there is nothing in it.
Anyone else?
