Macbook Pro 2015 not recognising upgraded NVMe SSD
I wanted to upgrade my 2015 MBP with a new Kingston A2000 NVMe SSD, because the original one was running out of space. With an external enclosure formatted the new SSD to APFS and installed macOS Monterey (12.6) on it also. Using a Sintech adapter I plugged it in, but it is nowhere to be found in Disk Utility. The SSD is alao new and works on both mac and windows with an external enclosure.
Any ideas? Maybe the syntech adapter is bad?
