Buying specifically for a Mac is generally not possible because that exact version was never released for macOS. Microsoft released Office for Mac 2011 as the counterpart to the Windows 2010 version.

While Microsoft no longer sells older versions directly, you can still find them through third-party retailers: Microsoft Office Mac 2011 Home and Student Go to product viewer dialog for this item.

: An even older version is available on eBay for approximately $19.50 .
