Why Can’t I Copy Files to Desktop (Error Code – 8058)?

In some cases, users may get a message The operation cannot be completed because an unexpected error occurred when they try to copy files or folders to the Desktop. At the same time, there are no problems with creating new items there. Repairing the Disk Permissions using Disk Utility usually does not help.

Why Does the System Refuse to Copy Files to the Desktop?

The thing is the Mac operating system uses a special construct, known as a plist. It is a short word for a “preference list”. The .plist file contains the preference settings for a particular application.

Sometimes such files get corrupted, which is hardly identifiable. This is known to be one of the macOS weak points. The system often does not know about the problem, so it does not send any alerts about it. As a result, a user is also unaware of the corruption. Meanwhile, an app with corrupted plists tries to read them, fails at it and starts malfunctioning. In most cases, it is the reason why it cannot be copied to the Desktop.

To solve the problem, you can drag and drop the plist to the Trash, and relaunch the app. By doing it, you delete the previous preferences that may be corrupted. You should not delete a .plist file permanently before reopening the application.

Deleting plists may cause losing some of your app’s settings, but you can set them up again.

To find plist files for a specific application, go to the /Library/Preferences folder.

The problem may also lie in wrong permissions in the hidden Autosave Information folder. This folder is used by native applications to mark different versions of documents every time you make some changes to them before saving to other locations.

  2. Click the Autosave Information
