I have worked on a Mac for many years and have very few issues with Poser. DAZ Studio, especially the newer DSON plugin on the other hand has problems. At least for me on Yosemite. Yes, you have to check and update the Python scripts and some older stuff no longer works. I use a 3D Connexion 3D mouse and it is awesome for posing, etc. DS does NOT support 3D mice. I also use a Kensington Expert Mouse trackball, which make working very fast once you get used to it.

As for those who like to riff on the cost of a Apple, they do so from basic ignorance. Yes, you can build a nice set-up cheaper if you have the tech know-how. The difference comes into play when you talk about resale, included software and ease of use right out of the box. If you actually compare specs, software included and resale value directly at retail prices, Mac generally is a better deal. Security is also generally better. No, they are not immune, but better and easier to maintain.

If you are an experienced tech or field service engineer who usually uses open source software (free or pirated), then yes, a Windows unit can be built on the cheap. I do not argue that. Those are the actual caveats. Look at the whole picture... ALL of it. The difference really boils down to what one is used to using.

And YES, I understand there are plug-in issues with El Capitan. Same with Adobe CS5 Products - if you rely on an older version of Photoshop, Illustrator or Indesign (as I do), then stop at Yosemite. Mac does not run Corel Paint Shop Pro BTW. By the same token, Windows will not run Artmatic Pro or Voyager. Check all of your software if you want to switch. And yes, Mac updates are free - unlike Windows.
