If some issue causes Screenwriter to crash, we need to get the crash log. All of your recent crash logs can be accessed inside Apple's Console app.
The Console app can be run either by searching for it using the Spotlight search icon in the upper right menu bar, or by opening the Console app, which is located in the /Applications/Utilities.
Once you open the Console app, you'll see three columns. In the left column, select the User Reports folder. This will display a list in the second column of all of the recent crash logs for Movie Magic Screenwriter (or Dramatica Story Expert):
Select the crash log with Screenwriter's name and the relevant date. Then do one of the following:
1) If you have a specific email address, use the Share icon at the top of the Console window to send the crash log as an attachment to the desired email address.
2) RIGHT-CLICK on the crash log filename, and select the "Reveal in Finder" menu item. Now you can drag the crash log file into an email message response to your support ticket.
3) Once you've clicked on the crash log filename in the second column, you will see the details of that crash log appear in the third (right-most) column. You can click in that column, then do a Select All (CMD+A) and Copy (CMD+C), then Paste (CMD+V) into an email message response to your support ticket.
