title: Deleting VBA code in the Personal Workbook (Excel for Mac) - can't unhide
body: <p>I was trying to create VBA code in Excel for Mac and save it in the Personal Macro Workbook. The VBA code does not work and I would like to delete it.</p>
  
  <p>I went to <strong>Developer -> Macros -> Delete</strong> but I got the message "Cannot edit a macro on a hidden workbook - Unhide the workbook using the unhide command".
  So I went to <strong>Format -> Sheet</strong> but the unhide command was not available.</p>
  
  <p>Then I thought, maybe the worksheet is protected? I went to <strong>Review -> Protection -> Workbook</strong>, but I have no password to input... it says it is optional anyway. I unclick "Protect Structure" but now I can't click "OK" anymore so I am stuck...</p>
