Hi CanArslan1,
Toolbox is used when creating UserForms, while it is not available to create UserForms in Office 2016 for Mac, thus the Toolbox button is grayed out in visual basic.
We suggest you vote for the related uservoice about enabling VBA Support for creating and editing UserForms in Office 2016 for Mac.
Or you can send feedback to the related team via the feedback tool in the upper right corner of Office app .
This is the best way to let the related team know your ideas and make our products better for you and others.
Thanks for your understanding.
Regards,
Tina
