After updating to macOS Catalina, you might discover a new folder called Relocated Items on your desktop. Don't worry; there's nothing wrong with your computer. Here's what you should know about this folder -- and what to do with it.

What is the Relocated Items folder?

During the upgrade process to macOS Catalina, your computer might determine that some files can't get moved to a new location or may not be compatible with the update's new security settings. When this occurs, it places these unedited files into the Relocated Items folder on your desktop.

You shouldn't delete this folder sight unseen. Instead, take some time and look at the files in question. Move essential data to a new location while leaving everything else in place.

Okay, let's delete this folder

After reviewing the contents of the Relocated Items folder and moving important files to a new location, it's time to delete the folder from your desktop.

Depending on the contents of the folder, deleting it might be as simple as right-clicking and selecting Move to Trash. If, when attempting to do so, you get an error message, deleting the folder might take a few more steps. Error messages could include wording such as 'this folder can't be modified or deleted.. ' or 'the operation can't be completed ..'

To delete the folder under this scenario, you'll need to disable System Integrity Protection (SIP).
