My Mac Studio is running Ventura 13.6 and I've followed your KB guide for M1 chips:
I've updated to the recommended firmware using the CLI Terminal method, and installed the recommended DEXT driver. I've rebooted the Mac and the Pegasus and the raid will still not mount. I'm using Apple's TB2 to TB3 adapter. When I look into my Thunderbolt connections it does not detect the Pegasus. When I connect the Pegasus to my Mac Pro 2013, it works fine. Any suggestions?
