<< Solved >> OpenCore 970 evo plus issues

[BlvckBytes]

Hey guys!

I've got myself a new SSD today, the Samsung 970 EVO Plus 2TB. My issue is, that OpenCore seems to not like this new disk. When I boot from it, the verbose screen is a little faster than usual (like it's skipping something) and the apple-logo with it's progress-bar at 0% stays for like 10 seconds. Then, the login-prompt appears. Once logged in, everything is super slow and seems off.

YES - the firmware is already up2date, checked with UNetbootin and the correct firmware-iso.
Also, my old Clover-Setup works fine with it, no issues, no lags, no high temperatures, instant boot - everything like before, with the 970 EVO 1TB.

Am I missing something here? Does OC not support the plus-version yet, should I open a new issue, do I miss any EFI-drivers? Strange things...

I use Catalina 10.15.4 opencore 0.5.8 and Samsung 970 evo plus 250 gb. All good working.

Did you ever run 0.5.7 with 970 evo plus aswell? Maybe they've fixed something with the latest release... I'll try to update later and get back to you.

No, I installed immediately opencore 0.5.8 and i use NVMEfix.kext

Thank you very much! This was it!

NVMeFix.kext is only supposed to manage proper SSD sleep, AFAIK, I had this before too.

What changed it, as far as I can judge:
* OpenCore update - new BOOTx64.efi, new OpenCore.efi, new Bootstrap.efi
* This update contained a new EFI driver: new NvmExpressDxe.efi

I hope this fix will work for sure, since this is just the first boot. Thank you a lot for your tip, tho

Hello BlvckBytes,

Would you be nice enough to confirm that everything works smoothly since your last post ?

Follow-up questions:

• Does the build with the 970 EVO PLUS is a dual boot with Windows ?
• Does the 970 EVO PLUS is your system SSD for MAC OS ?
• What MAC OS version do you run on the 970 EVO PLUS ?

I Thank you in advance for you time.

Cheers,

M.

Yup, everything fine to this day, no issues.

Yes, I dual boot with windows, works fine. OSX is on the latest version out publicly (10.15.6).
