Hi!
I have small little issue with my NVMe Crucial P1 500GB.
I Have iMac 5k 27' Late 2015 With Fusion Drive (1TB HDD + 32GB Apple SSD)
I decided to buy Crucial P1 because of recommendation from YT and many other places. My problem I that:
i have installed on Apple HDD OSX Catalina and formate the 32GB Apple SSD (infuse fusion drive) - everything works normally but a little bit slow because of OS X on HDD.
Then I tried to install NVMe Crucial P1 with Adapter on motherboard (no-name, longer adapter - not Sintech) and that's where problems happen. When Crucial P1 is installed I have totally non response from iMac. Cant even Boot, not even a Fan Spin. When I remove NVMe with only HDD there is no problem at all. Installing back Crucial P1 and nothing happens... I Have tried internet recovery key combination, everything but my iMac won't even start with NVMe plugged in... Without, everything is ok. So lets sum up:
Apple HDD + Apple SSD = everything is ok
Apple SSD = everything is ok
Apple HDD = everything is ok
Apple HDD (with OS X preinstalled) + NVMe = No boot No Power No Fan spin, nothing
Can someone please tell me if I am doing something wrong? I tried on Catalna, Mojave, El Capitan and Catalina with USB but none of this will even try to start. Totally dead.
Maybe it is a adapter fault? Maybe I have bought a non compatible ssd? ( but on snitch site P1 is as compatible)
