sequential numbering of worksheets for invoices on Apple system

[keithjmccall51]

Can anyone advise whether we can create sequential numbering on worksheets to create unique invoices on an iMac , like kutools does on windows?

If you start your sequence in A2 and, for example, you want your starting number to be 123, then the starting formula in A2, copied down the rows, is:
=ROW()-2+123
