things to consider....why mac has never truly been on the industrial scene;
1) Training; the number of people that have use a pc for a decade at work, and you would slap a Mac under their nose, you would find a huge drop in productivity as people ( the large majority of users in the workforce) have never seen, never mind used a mac for work.
2) Security; buying mac to run windows in a vm is funny, if that is your purpose for security reason, then why no step up to the next generation industry systems instead of buying expensive mac desktops; Virtual servers running desktops for users, and run dummy terminals (minimal workstations) on the desk. cheap, safer and far more controlling than either having a mac or pc on a desk. (and yes I see this being implemented in Schools and companies more and more, why? cheaper and far more secure than a desktop of any kind)
3) Price; Mac is twice or trice the price of a PC for a work environment at best, 99% of user have zero need for the power and capabilities of a mac over a workstation desktop pc, if mac made a "workstation desktop" that competes with the dell and Hp of the industrial world, then I says why no.
4) software; why buy a mac? my company already has 1000 license of MS office for pc, they will not convert those into 1000 Mac office licenses, so aside the price of the mac desktop I also have to consider buying more windows license to run software I have to convert to mac software licenses double my costs for my office.
Note; in my arguments above I am not speaking about an office starting from 0. then argument 1 & 4 could be mitigate by hiring mac lovers/users and purchase of mac software to begin with.
Personal note; and this will pass as judgmental, but is truly a fact, I have been around mac and pc for last 30 years, and in the last 10 years the more I have to interact with mac "companies" the more I find the "mac" users to be hipsters that think they know everything about their macs, compared to the pc users that at time painfully admits their barely know how to use a mouse.
The truth is neither know anything about their personal computer, but the Mac user will try their best to tell you what to do on their mac when your better qualified than they are to fix the issue.
I, as a professional traveling technician, covering 10 states, and about 3500 companies, have no issue having someone using a mac for their corp, but have serious reservations in my interactions with their IT and user, that always blame professional software and hardware and have problems understanding the relationship with drivers and lack of support most mac drivers have from cops that make the hardware ,why is that?, it is because mac computers is less than 1% of the industry standard systems, and not worth millions of dollars investments by most corps.
This sad fact; it is not a fight against mac's, it is because apple still in this day an age force companies to jump through so many hoops to produce hardware and drivers for the mac that it is too much work than produce drivers for a windows based system. This has been the issue with apple hipster mentality from the start and why IBM and other PC based companies have taken over the industry.
Mac best purpose is graphical and photography, without a doubt always have been and always will be the better computer for advertising and printing shops designers etc... you can have a mix of a few Mac inside a corporation of 1000's of desktop workstation using office.
