    <p>I'm developing a sandboxed Mac App Store app which asks the user where to save files it downloads from elsewhere. I have this code to get the folder from the user (stripping out some error checking):</p> <pre><code>NSOpenPanel* openPanel = [NSOpenPanel openPanel]; [openPanel setAllowsMultipleSelection:NO]; [openPanel setCanChooseDirectories:YES]; [openPanel setResolvesAliases:YES]; NSInteger result = [openPanel runModal]; NSArray* urls = [openPanel URLs]; NSURL* folderURL = [urls objectAtIndex:0]; NSError* error; NSData* bookmakeData = [folderURL bookmarkDataWithOptions:NSURLBookmarkCreationWithSecurityScope includingResourceValuesForKeys:nil relativeToURL:nil error:&amp;error]; _saveFolderBookmark = bookmakeData; </code></pre> <p>and when it comes time to move a file into this folder, I have this code:</p> <pre><code>BOOL isStale; NSError* error; NSURL* saveFolder = [NSURL URLByResolvingBookmarkData:_saveFolderBookmark options:NSURLBookmarkCreationWithSecurityScope relativeToURL:nil bookmarkDataIsStale:&amp;isStale error:&amp;error]; BOOL success = [saveFolder startAccessingSecurityScopedResource]; // Move the file somewhere else NSWorkspace* workspace = [NSWorkspace sharedWorkspace]; NSInteger operationTag; BOOL copied = [workspace performFileOperation:NSWorkspaceMoveOperation source:[[self getDocumentsFolder] path] destination:[saveFolder path] files:[NSArray arrayWithObject:filename] tag:&amp;operationTag]; [saveFolder stopAccessingSecurityScopedResource]; </code></pre> <p>Which is a lot of code to list to say that startAccessingSecurityScopedResource never returns success for me, either immediately after getting the ULR from NSOpenPanel or in a later run, with the bookmark data being saved in NSUserDefaults.</p> <p>In the entitlements file, amongst other items, I have:</p> <pre><code>&lt;key&gt;com.apple.security.files.bookmarks.app-scope&lt;/key&gt; &lt;true/&gt; </code></pre> <p>Is there anything wrong with this code?</p>

    1. COAre you seeing any console messages? Also, double check the code-signing to make sure that is configured correctly.

    2. COIn your example, it isn't clear where the `urls` array comes from after the open panel is finished.

    3. COI managed to edit out the line getting urls when I removed the error checking. I've put it back again. There are no messages in the console around the line calling startAccessingSecurityScopedResource.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
