I am trying to get rid of all backups of XCode.app in my Time Machine backup. When I enter Time Machine and select "Delete all Backups of XCode" in the context menu, it shows some deletion progress in the Finder and DesktopServiceHelper is busy for a moment until it displays the following error message:
The operation can’t be completed because some items had to be skipped. For each item, choose File > Get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again.
Any idea how this can be solved? I could only find one related thread on Google which didn't provide any helpful information.
