Before updating to macOS 15 Sequoia, I used to be able to create file bookmarks with this code:

let openPanel = NSOpenPanel()
openPanel.runModal()
let url = openPanel.urls[0]
do {
    let _ = try url.bookmarkData(options: [.withSecurityScope])
} catch {
    print(error)
}

Now I get an error

Error Domain=NSCocoaErrorDomain Code=256 "Failed to retrieve app-scope key"

These are the entitlements:

com.apple.security.app-sandbox
com.apple.security.files.user-selected.read-write
com.apple.security.files.bookmarks.app-scope

Strangely, my own apps continued working, after updating to macOS 15 some days ago, until a few moments ago. Then it seems that all of a sudden my existing bookmarks couldn't be resolved anymore, and no new bookmarks could be created. What could be the problem?

Thank you, that was very helpful.

What you're hitting is bug in "ScopedBookmarksAgent" which can cause it hang if it happens to have been launched when the keychain was also locked (for example, late in the screen lock process). That bug is fixed as of macOS 15.1 beta 4.

If you're hitting it regularly during development, you can resolve the issue by killing ScopedBookmarksAgent (you may also need to kill and relaunch your app, depending on what state it ends up). On the user side, a log out (or reboot) should resolve the issue.

Today, mysteriously, the sample code works again. How could this possibly happen? Yesterday all my App Store apps weren't able to resolve and create file bookmarks, and today they work again.

It's hard to guess at an exact cause, but this particular error:

Error Domain=NSCocoaErrorDomain Code=256 "Failed to retrieve app-scope key"

...comes from one of the intermediate daemons involved in resolving security scoped bookmarks. If there was a problem in one of the lower level daemons it communicated with, then it's possible the problem would resolve itself if/when that daemon restarted.

We're seeing the same thing in the wild. Security Scoped Bookmarks on macOS 15 don't resolve after a while.

Reports are that a device restart helps, but only for a little while. Trying to gather more data from some pretty angry users right now... Same app/binary works on lower macOS versions. App is a sandboxed.

Something is very broken resolving Security Scoped Bookmarks on Sequoia.

Edit to add: Same error is indicated (256).

Uh o. I have a sandbox app that uses security scoped bookmarks. Nobody's mentioned this to me so far.

Just to throw some spaghetti at the wall, is it possible this could be related to not balancing -startAccessingSecurityScopedResource calls with -stopAccessingSecurityScopedResource when you are done with the file?

If I remember from many years ago not doing this would eventually cause open/save panels etc. to no longer work in your app until after you reboot your Mac.

If you're having this kind of issue in your app, the first and most important step is to file bugs. If you've filed bugs, please post the bug numbers here.

I don't think so. This happened both with my App Store published app and with a sample app I had just created to reproduce the issue. Even after restarting both apps they had the same issue. It only disappeared the day after.
