When I was studying radio production at uni back in 2010, the Adobe Audition editing suite was rammed full of 2009 iMacs, all running WinXP. It was a bit of a headfuck for a moment, but iMac hardware was second to none, the uni must have got a decent discount from Apple to buy that many, and at the time Audition was Windows only.

And to be fair, they made for excellent editing machines.
