Hello ,

Thank you for your question.

It appears each store may have custom fixtures created and there is no single answer for you. As you will see in a moment, some are even designed in-house. But hopefully the following will be useful links to get you to the results you desire.

For example, this store in New Zealand used Allen and Chapman for their MAC displays:

David Nice Builders has created custom fixtures for MAC displays:

Fixture Pro claims to having created some things for MAC, however no longer listed on their current website. You might contact them:

Ebay even gets some MAC display fixtures:

It also appears that MAC does some of this in-house as they have ads to hire industrial designers:
