If you're using Microsoft Excel on a Mac, you can insert a row by following these steps:

1. Open the Excel document that you want to insert a row into.
2. Click on the cell where you want to insert the row.
3. Click the "Insert" tab on the ribbon at the top of the screen.
4. Click the "Insert Sheet Rows" button in the "Rows" section of the "Insert" tab. This will insert a new row above the row that you selected in step 2.

You can also insert multiple rows at once by selecting multiple cells before clicking the "Insert Sheet Rows" button. For example, if you want to insert two rows, you would select two cells in the row where you want to insert the new rows, then click the "Insert Sheet Rows" button.

If you want to insert a row below the row that you selected, you can click the "Insert Sheet Rows" button in the "Rows" section of the "Insert" tab, or you can right-click on the row and select "Insert Row" from the menu that appears.

You can also insert a row by clicking on the "Home" tab and then clicking the "Insert" button in the "Cells" section. When you do this, a menu will appear with various options for inserting cells, including rows. Just click on "Insert Row" to insert a new row above the row that you selected.
