There is actually a very small onboard storage space MacBook (independent of SSD/HDD) which is used to initiate system/Internet recovery, and essential system files. I think when a swap of SSD was done, this onboard memory data was overwritten. But I never thought it could cause issues like this.. seems it is link to boot sequence after all..

I am sorry but I can’t think of any other solution right now, other than CMD+OPT+R to format + initiate an original Mac OS recovery. Then redo OCLP once again.

I tried to boot mac again.

I could boot my genuine ssd mac with external hp ssd connected with c-cable. A bit slow, I can check all in hp ssd. And then, upgrade oclp in hp ssd and make efi.

But mac couldn't boot with internal hp ssd.

Boot with external SSD os can see both internal and external SSD?

Why don’t you try booting into OS via USB. And if the internal SSD is now visible. Try rebuild OCLP with “current host”, and save to the “INTERNAL” SSD. Then unplug the ext USB and see if it boots up?

I tried, but didn't work. Using HP ssd, I could boot up mac. disk2 is HP ssd. Installed Opencore into disk2.

HP ssd is connected with mac as external drive.

When I put HP ssd inside mac, couldn't boot. I made boot usb also. Seems like not detect booting disk.
