Here are symptoms of ‘unable to expand zip file’ issue and error codes and messages you may receive with it:

  1. Error 1: Operation not permitted - If you get ‘unable to expand zip Mac error 1’ it often means you don’t have permission to access or unzip file. Maybe you can’t read or write to it, or the folder you’re extracting to doesn’t allow it. Sometimes, you may also get ‘Error 1: unable to expand no such process’ if your system blocks extracting zip file directly to main directory.
  2. Error 2: No such file or directory - This means the zip file you’re opening isn’t where you’re looking for it. This might occur if “Archive Utility” doesn’t recognize file name and assumes file isn’t there.
