I have seen a suggestion that in these circumstances we should just use the Unhide option in the Window menu, but that option is grayed out. If, with the Personal Macro Workbook still unopen, we try to record a macro in Personal Macro Workbook we get the error message 'Personal macro workbook in the startup folder must stay open for recording'. However, when Personal Macro Workbook is not open the Macros window in other workbooks (reached by clicking Macros on the Developer tab of the ribbon) is empty. We have put some macros (copied from another computer) in Personal Macro Workbook and can run them from other workbooks if Personal Macro Workbook is open. Unable to see and/or run macros in Personal Macro Workbook on Apple Mac unless that workbook is open
