Hello All. I'm new to the AMD club, and delighted to be here! I have successfully built a "Ryzentosh" with the bleeding-edge Asus Crosshair x870e Hero MB and a Ryzen 9950x. Works perfectly on Sequoia 15.3.1, including Broadcom Wifi, Intel 2.5 Gb ethernet. Blown away by the computational performance. Many helpful posts on this site made it happen. Thanks!
