So this is more just an FYI, but my current IMac that I use does not support X12 due to older video card and older OS system. So was looking to get a NEW computer and have loved the reliability of the IMac, but was frustrated the the latest IMacs that were just released still had subpar video cards. So have been doing a lot of research with Chief Architect Help Desk, Apple, and other PC manufacturers like Dell/HP and just wanted to share in case any other Chief Users out there were looking to invest in a New Mac.
The end result is this: the current AMD Pro Vega video card in the 2019 IMacs will run Chief X12, but Chief is moving towards all their platforms using "ray-tracing" video cards that support Direct X, or the Metal platforms. The Nvidia RTX 2080ti card is one of the best cards on the market to support the Direct X platform and ray tracing. However, Apple only uses AMD chips at the time. (and yes you can use add on hardware that reads the Nvidia card, but not looking to invest $3800 in a new IMac, and then have to use an EPU to get the graphics correct). So Chief advised that IF I wanted to stay with Apple products, they advised waiting until later this year to see if AMD and Apple's new releases will have the "Metal" platform on their graphics cards, which will support future versions of where Chief is headed.
Therefore, although I hate not upgrading and using X12, and I considered switching to a PC, which are very good, I decided to wait it out and see what Apple does later this year with their upgrades and newer video cards with AMD. Here is a link to explain more of the Metal platform that Apple is using. https://developer.apple.com/metal/
Since I had done so much research, just wanted to share with anyone who was looking to get a new Mac this year. Again, current Macs will support and run Chief great, I just wanted to make sure that when I invest in a new computer, that it will still run Chief upgrades well 2-3 years from now. Hope this helps!
