Boardview for an Apple logic board numbered 820-00138, packed in ZIP; the leading 55946 looks like a catalogue index and no Mac model is named. Apple's 820-xxxxx numbers identify the logic board and are printed on the PCB, so match that code before relying on the layout. Once extracted, the file opens in viewers such as OpenBoardView, FlexBV or Boardviewer, letting you search a part reference, see pins and nets, and follow a rail to its source while chasing a short or a missing voltage.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
