    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

     

    Step 1

     

    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.

     

    Enter the name of the crashed application or process in the Filter text field. Post the messages from the time of the last crash, if any — the text, please, not a screenshot.

     

    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

    Please do not indiscriminately dump thousands of lines from the log into a message.

     

    Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.

     

    Step 2

     

    Still in the Console window, look under User Diagnostic Reports for crash reports related to the process. The report name starts with the name of the crashed process, and ends with ".crash". Select the most recent report and post the entire contents — again, the text, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

    The camera icon is for posting screenshots. Please don't do that. Copy the text and paste it into a reply.

    Back up all data.

     

    Quit the application if it's running. Triple-click the line below to select it:

    ~/Library/Preferences/com.apple.QuickTimePlayerX.LSSharedFileList.plist


    Right-click or control-click the highlighted line and select Services Reveal from the contextual menu. A Finder window should open with a file selected. Move the selected file to the Desktop, leaving the window open. Relaunch the application and test. If there's no change, quit again and put the file you moved back where it was, overwriting the one that may have been created in its place. Otherwise, delete the file you moved.

    Launch the Terminal application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

     

    Triple-click the line below to select it, then drag or copy the text — do not type it — into the Terminal window and press return:

     

    ls -Odel ~/L*/Preferences; ls -Oel $_/com.apple.QuickT*

     

    Post any lines of output that appear below what you entered — the text, please, not a screenshot.

    Please test after moving this file to the Desktop, same way as before:

     

    ~/Library/Preferences/com.apple.quicktimeplayer.plist

    Please don't post any more crash reports unless requested. Try moving this folder:

     

    ~/Library/Containers/com.apple.QuickTimePlayerX
