Can you try with a different graphics card to test? You can buy a replacement then send it back if it doesn’t resolve the issue.
I believe the new MacMinis are all soldered PCIe storage these days, they don’t have a SATA port anymore. You could connect your SSD via a USB3 enclosure and it would be almost the same speed as in your MacPro. _ Regards Sam Mullen +44 (0)7747778022 <tel://+447747778022> [email protected] <mailto:[email protected]> www.macambulance.com <http://www.macambulance.com/> MacAmbulance Ltd.
