There were definitely advantages of a Mac for creatives back in the PowerPC era, either from platform lock-in (Mac only industry standard software) or real-world noticeable architectural performance advantages (between PPC and x86). That, with a few exceptions, disappeared with the transition to x86/Intel and now with the move Arm, you're starting to see these differences again - although i'd argue it's within specific areas/workflows.
And like others have said around dev/devops, unless you have specific requirements or platform restrictions, then it's now mostly down to what someone knows.
IMO, i do think a lot is down to existing stereotypes, influences and because of the badge. I see this a lot with upper management types requesting Mac's yet their sole job revolves around Microsoft Office where it'll actually be a hinderance and/or a non-starter to switch to MacOS given some of the (now) feature parity (within Office) between platforms. Plus, you don't need a £2.5k MBP to look at "cosy" furniture on Pinterest whilst on a Teams call tied to a desk
Macs also generally keep there resell value much higher than Windows based hardware which businesses like.
Perhaps but, from a business POV, an Apple estate is costly to run, maintain and manage as you're predominantly relying on third-party and custom solutions.
It's one area Microsoft has had sown up for decades where Apple has severely dropped the ball on other than their brief toe dip with their 'server' line (hardware and software) which they then abandoning it all.
In any case I don't know why in the corporate world organisations would subject themselves to having to support both Windows and MacOS.
Ideally you don't other than for specific use cases for someone to do their role. But you have bright ideas from management, like BYOD, that prevent you doing that.
