[QUOTE="Macsolver, post: 1941364, member: 381451"] You may be able to get it working with Monterey if you create a new USB OpenCore Legacy Patcher installer booting from an older version of OSX with the GPU in place at the time you create the new USB installer. If you can boot from the new USB Monterey installer, you should be able to save a new set of EFI patches to the existing Monterey Boot disk that should then work with the card. Might be a idea to first check that the GPU power draw on the PCIe buss is less than the combined limit for the Mac Pro PCIe power buss (allowing for all PCIe cards). I have seen it somewhere on line but I can not remember what it was, sorry. [/QUOTE]
