Hi everyone, I'm not new to the world of hackintosh, in the past years I built my first pc with snow leopard, then another with lion and in recent times my Optiplex 7010 with Catalina the one in signature and an Optiplex 3020 with Catalina.

Only now I'm doing an Optiplex 3050 i5-7500 3,4 ghz - Intel HD 630 video - Audio Alc 255 - 08NPPY motherboard of a colleague of mine and I am in difficulty.

I followed the guide to set up the DVMT memory, I set the bios as in the first post of this discussion, I created the usb stick with mojave and replaced the EFI folder with the most updated one in this discussion, i.e. the r4.

But unfortunately at startup, the apple logo appears and then it restarts.

I also tried with a stick with catalina, but nothing to do.



Can you give me a hand please?

thanks a lot

If you changed the DVMT prealloc using Grub shell, then please try the attached EFI.

I managed to install Mojave without the attached folder.

Now I ran MultiBeast for Mojave and try to upgrade to Catalina.

In the EFI partition of the PC, do I copy the folder you attached to me?

You don't need MultiBeast. Just copy the EFI folder from the EFI partition of your USB flash drive to the EFI partition of the main system drive.

After that, you can continue to update to Catalina.

All right

I preferred a clean reinstall with Catalina.

Now I do a little test to see if everything works and update to 10.15.4

Thank you for your help.
If I still need you I will write to you.

Unfortunately it does not update.

Download update, restart, start from Install preboot from preboot, remain still with the apple and does not continue.

Some idea?

Boot in verbose mode and post a picture of where it gets stuck.
 
Here's where it hangs

Hmm... It looks like it's getting stuck at the Aptio fix...

Please try this EFI.

With verbose mode we see that it goes a little further, but then it stops again, always from Install prebooter from prebooter
