Damn it, thought they rehired one of the original developers of Poser on macOS and intern would be working on a fully capable Apple Silicon~Metal release; so as a result I recently purchased Poser 13 in anticipation of future proof upgrades.  This deprecation for macOS Poser doesn't make the least bit of sense given the fact that Apple has upcoming releases of M series (Max/Ultra/Extreme) GPUs with capabilities that'll mirror the fastest Nvidia GPUs on the market.  I don't understand why only now is it feasible to cut off macOS while it's at the cusp of a sustainable, lucrative industry revolution!
