Hi, I have 2015 MacBook Pro with an upgraded SSD, a Samsung 970 Pro M.2 SSD. I update Mac OS to 11.1 and want to made clean install. Tried to boot in recovery mode, but Disk Utility doesn’t recognize the SSD. In terminal with command “diskutil list” I see only SD card and recovery 2GB disk and bunch of small partitions about 500kb. When I boot the system I can see the SSD and system working fine.
Some SSD adapter cards aren’t compatible with older versions of macOS, therefore they do not show up. I know for OWC drives the minimum version they work in is macOS High Sierra, it should probably be the same for the M.2 to mini PCIe adapter you’re using.
