    v1 v2  
    1 macOS asks for permission to access the Desktop because ChimeraX sets the current working directory to ~/Desktop using os.chdir().  The chdir() call does not trigger the permission dialog, but any subsequent os.getcwd() call does.  Startup does a getcwd() when the file history contains many thumbnail images because HtmlView.setHtml() in chimerax.ui.widgets() makes a temporary file to work around a QtWebEngine size limitation in setHtml() and making a NamedTemporaryFile uses getcwd() because it considers the current directory for the location.  Here is the stack trace for where getcwd is called.
