For some time I’ve been having trouble with drag-and-drop on my Macbook. In the finder a popup would show or the file rename action would trigger. Turns out there is a setting I missed during one of the MacOs upgrades.

Turning off “Look up & data detectors” fixed the drag-and-drop for me. I’m using the defaults – if you’re changing stuff – disabling the “one finger” action is the key.
