If you said "Don't save" then your current file is lost for good.
The autosave backup will have been cleared as well because you chose to shut down properly.
The best you will have is the last save and the BPN file which will be the save before that.
If you think you saved it somewhere but can't remember where then do a search on your entire hard drive for the file name.
You should be able to search for the file name or any PLN fine created within a certain date range.
Sorry I am not a Mac user so don't know how to do that.
This will find all the files with that name (or within the date range) and you can choose which is the newest.
