Don't what's going on. Might a faulty ssd

Your bootrom is wierd.
Latest bootrom for cMP is 144.0.0.0.0

Have you initialised the ssd after installation.
Is it plugged into standard sata port.

Your not alone

Caution! Troubles with 870 evo drives on cMP 5,1 !

Hi people, I wanted to install Mojave on a new 870 evo drive and it was a desaster ! In difference to my 860 ‘s the installer didn’t reboot into the 2’nd phase . I had to hard reboot ? Later on , the drive even had’nt been recognized . That happened also after starting from another mojave drive...

BootROM is being set by Opencore.

How is the 870 installed? PCIe card or in one of the drive bays?

Say no more....
I have lost count how many problems people have when they try and run unofficial systems.

I have a similar system and same NMVe blade. has worked perfectly since first installed. My PCIe card listed in signature is dual, so I have two blades both EVO 970.

Oh... and I am running OpenCore @MarkC426, so I think it is hard to jump to conclusions without knowing more from OP (whether using SATA or PCIe etc).

EDIT: Just realized OP is referring to a SSD and not NMVe. Disregard my comment then.

Thanks, I'm directly to drive bays. I notice that after warm boot. it will disappear. If I start from cool boot, it's there

I have another EVO 970 plus as well which installed in Highpoint card, works very well as my boot disk

Hmm.. 870 EVO here and it works fine on my end - just had to format it using disk utility for Mojave.

how about after warm reboot? My one was already format to JHFS+

I'm use OpenCore 0.6.8 + Catalian

Is it a 870 qvo?

I experienced the warm boot issue with a qvo recently on a customer machine. It ended by using the qvo as a data drive cause it wasnt returnable.

Well maybe it is not playing well with SATA II which is all you get from the drive bays. A PCIe card to hold the SSD would give you SATA III. Perhaps try it on the Highpoint card as a test?

I have the same issue with a 2019 27” iMac I’ve looked everywhere but there seems to not be any firmware for Mac for the drive…

Hi there,

Very common issue with 870 Evo's warm boot they don't mount but do on cold boots.

Mine works "sometimes" on warm boot after I updated the firmware, see here for the update and the instructions to update
