I have attached an error log, dsdt dump and my efi file (removed some kexts to file file size requirement

I made donation of $20 using gma3207423@gmail.com I wish it could me more but I am a little stretched due to this covid

I really need to get OS X working again

TIA

I lost OSX boot loader in bios from my failed attempts before contacting you (reset NVRAM) can only boot from USB for now.

My main concern is that my SAS hard drives are not present.. what kext do I need for that?

Attached please find my modded USB config.plist file, if you need Runme app Send me file let me now how I can share it.

 

Don't look now but there's a huge line forming to sing your praises!

 

Thanks!!

Hi,

I am a bit confused by your request

Catalina originally used clover but when I updated my processors from 2x E5-2637v3(4core 8threads) to 2x E5-2690v4(14core 28threads) the Clover based EFI stopped booting.

I run the sendme I posted using that EFI because I thought that is what you wanted to see.

I have since replaced it with open core EFI to boot OSX with out the USB

now I am not sure what you want please advise should I go back to the clover EFI for this?

This is the modded x99 opencore EFI that boots - run the runme app from this install

Send me iMac Catalina 32321

note:

the internal LSI SAS2 2308 has 2x 8tb hard drives connected that do not show up anymore

note: Windows 10 hangs when started from openCore

also sometimes catalina now boots to  a black screen and must be restarted is this normal for opencore?

the Atto express H680 is listed - ok not the problem

The issue with Windows 10 hanging when loaded via opencore menu has to do with the DSDT.aml file

without it (dsdt.aml disabled) Windows 10 boots correctly but Catalina fails

so for now I'm using window boot manager for windows 10 and openCore bootloader for Catalina

maybe ther folks over at opencore can address this issue ina future update

@MaLd0n Thanks again for all your help!

Hey Man,

Please have a look @ my Send me.. see if you can spot the problem with opencore boot loader:

https://drive.google.com/file/d/13DsGxAzOvQmDO42ghWsXg4jvg5GNhs5v/view?usp=sharing

EDIT:

I finally got my internal SAS controller listed using OWCJupiterAdapter.kext and now the SAS OSX controller shows in System Report.

SAS partition shows up in boot options with Clover boot loader but will not post:

here is link to CLove EFI as well:

https://drive.google.com/file/d/1uoWdoLp9K6jeS7-2-Qjser3ObU0zRXZT/view?usp=sharing

bios set to all UEFI except video, but when Catalina or Big Sur loads the SAS drives are still missing with opencore and clover EFI list SAS drives but OSX fails to load.

 

TIA
