Hi,
I've got an iMac 27" (late 2013) and wanted to make a final update.
I've bought an Crucial P1NVMe PCIe 2280 M.2 SSD.
I've installed the SSD (after a full demount).
After start-up the device immediately mentions it can't read the SSD.
Allthough, in the DiskUtility it is mentioned under the "tab" NVMExpress.
I've been looking around on the website of Crucial though I can't find anything helpfull...
Anyone?
First you are using the Crucial M.2 SSD on an unsupported computer since Crucial does not make a blade SSD for the Macs. Don't expect Crucial support (or any vendor) to assist you with an unsupported computer.
You should try using the Sintech adapter as that seems to be the one most users seem to recommend and find most reliable and compatible.
Within Disk Utility make sure to click "View" and select "Show All Devices" so that the physical SSD appears on the left pane of Disk Utility. Erase the whole physical SSD as GUID partition and APFS (top option).

I see no logical reason it would not work... I've done it on a mac mini 2011, on a MBP mid-2012 (respectively SSD 500 GB and 1 TB).
What happen if you try to select it in disk utility (as you see it) - is it greyed out ??
If you see it, but can't use it, I'm also curious : where is your macOS - are you booting from old drive connected externally ?
I’ll start again and be more precise.
I’ve placed a blade SSD and left the HDD in place.
After a simple restart I get the report: “Can’t read the installed device with this computer.”
when I open DiskUtility the SSD is shown (not greyed out). I can select it and then it even shows the details (such as size)...
I’ve tried restarting by the command alt-R-P to see whether I would be able to choose the SSD; no luck however...
Did you add an adapter for M.2 2280 --> to Apple Propriety connection?
Even though M.2 2280 and Apple's PCI-e SSD -- come with blade shape - please be mindful the compatibility issues.
M.2 2280 will NOT work as Apple's PCI-e propriety SSD, without adapter.
Even with adapter, there night be issues. OWC carries natively iMac compatible SSD, or on-line for OEM Apple parts.

THANKS! This was helpfull.
"Within Disk Utility make sure to click "View" and select "Show All

Utility. Erase the whole physical SSD as GUID partition and APFS (top

The button just mentioned ERASE --> so I didn't dare to press it. After further notice I read it also is used for formatting.
Thanks!
I'm out of the woods.

Yes, that can be confusing as Apple's methods differ from other operating systems. It also doesn't help that Apple now hides the physical drives from view by default making it even more confusing how to recreate a new partition table.
I'm glad you were able to resolve your issue.
Sounds like it needs to be formatted. Best process when changing drive is to clone old drive to new then test externally then swap out.
I’ve added Some more details in another response.
I was talking about a blade SSD and not a 2,5 inch SSD.
.
Probably formatted for Windows ??….
Well,
I actually ordered all the parts (incl. adapter for the blade SSD) as mentioned by Luke Miani (YouTube).
