I have recently installed a 1TB Samsung SSD and it refuses to reboot into macOS. I’ve freshly installed from OSX lion and updated to high sierra, all supported. I am going to try installing a firmware update and see what happens since I’m getting this every reboot. Though I can do a full shut down and it’ll boot right up. This problem doesn’t exist in Linux. Here is what it does in macOS during reboot:
Mac mini, macOS 12.7
The Samsung SSD is a poor choice for older Mac's that only have a SATA ll 3G drive controller.
What you need is a SATA ll 3G SSD or a SATA lll 6G SSD that is backwards compatible to 3G.
FWIW I've had good results with the PNY CS1311 and CS900 SSDs in older iMac's and Mac mini's.

Another very reliable option for older Mac's, is the 1TB OWC Mercury Electra 3G.

You're welcome.
If you can not return the Samsung SSD, put it into a Sabrent tool free enclosure and use it for a Clone backup.

From your description, it seems you have a dual boot macOS and Linux. It may be possible that there is an issue with the boot loader that was installed for Linux not playing well on reboot with macOS.
I have done the command+option+p+r at boot, how do you reset the SMC? And yes I do have a single APFS partition for macOS. I also have nothing but an apple keyboard, mouse and a dell monitor hooked up to it.
I guess you have already reset SMC and PRAM, and disconnected all unnecessary peripherals, and only High Sierra is installed to a one partition APFS (GUID) SSD?
This has been happening before I had tried Linux. Right now the SSD has been fully reformatted and only has high sierra installed.
This makes sense, thank you.
