I bought the Samsung 970PRO 1TB with sintech adapter, I did installed everything properly inside the computer itself and the MacOS Mojave VERSION: 10.14.5 - and I have a some problems with that.

-sleep mode - I'm trying to sleep my computer and it sometimes ok and sometimes the computer crash.

-startup - when I'm turning on my MacBook Pro it most of the time show me "flashing folder with questions
mark", and sometimes its turn on regular.

-restart - when im restart the computer it sometimes show me the flashing folder and sometimes its works fine.

I have tried to do some tutorials that explain how to write some different codes in terminal, it fixed it for 1 hour. but I think when in turn my computer off it restarting everything, and all the code is reseting.

please HELP ME!! :(

Don't do Time Machine. Reinstall the macOS again, a clean install. I have the mid 2015 full specs with a Samsung 970 EVO 500GB performing with flying colors.

Please help me :(
 
Are you using the long or short adapter?

Was the MacBook running the latest version of Mojave before installing the Samsung nvme?

You can find the bootrom version in system report.
 
Can you recommend diffrent best adapter for it?
I have always recommended the short green or black Sintech adapter. People have reported success with "no name" adapters from AliExpress too.

Is it possible that the drive and/or board is bending while inserted in the MacBook. Some users have reported a slight bend in the drive and/or adapter when using a long adapter. Some users have even cut/trimmed the long adapter to prevent bending.

I think you solved my problem!!!
I have tried to Release the screw so the ssd will be straight to the connector.
And it worked perfectly on the first turning on. I will try for a little time and will tell you if there is still problems!
Thank you so much!!!
