What is Error Code-43?
What is this error all about?
This message is popping up all the time while moving files
MacBook Pro 16″, 13.3
The error code is a File Not Found error. Ventura has had some trouble with a File Not Found error after renaming a parent folder it is found in, but the error dialog in that case specifically says File Not Found and is different from the one you are receiving. Is the error happening on an external HD?
Also, make sure to do a Safe Boot and confirm the problem is repeatable.
