I have a problem with MacPro 5.1 and OpenCore when I try to boot a 4TB Samsung 990 SSD at a PCIE-card with OS 12.7.6. Bootpicker shows "SSD_4TB - Data" partition and not the "SSD_4TB" where the system 12.6.7 is located. Boot freezes at the Apple logo and the "thermometer scale" just in the beginning. (It worked before upgrading the OpenCore.) Disc check shows normal. Several other discs, including SSD 1 TB, are working normally with 12.6.7 and does not show "...-Data" but only the name of the disc. Please help, what can I do?
