<< Solved >> Is it possible to add a DSDT patch without loading into Mac OS

[jc123]

I recently updated my clover version on my second PC without adding the correct patch that will allow my PC to boot into Mac OS ( it just black screens forever). Is it possible to add this patch without booting into Mac? Maybe from the clover boot config screen? I do have a working hack which I'm using at the moment with all the patch information. I don't have a bootable USB at the moment or a version of Mojave downloaded.

Attach the drive from the non-working system to the working one - Fix it - put it back.

Thanks, I'll use this as a last resort because my second PC is a laptop. The drive is fairly easy to access though.

You can use a USB to SATA adaptor.

Got one handy actually, but I just checked and the patch is already there. Not sure why clover 5058 will boot on my desktop but not on my laptop. Laptop just gives infinite black screen. =\

got any idea how to downgrade clover from 5058 to 4961?

The folder structure in the new(er) Clover has changed.
Make sure that all of your drivers are in the new location.

Each time that you update Clover a copy of your entire /EFI folder is saved to the system disk in /EFI-Backups.
To downgrade replace the /EFI folder on the EFI partition with the one from the latest backup.

Thanks for all the help, everything works properly again. I simple did as you recommended with the USB to SATA adapter then reinstalled 4961 on that drive. Much appreciated!

I'm still unsure why 5058 wont boot properly though. Also, even though it boots properly on my desktop there is no boot logo/progress indicator just a black screen then it instantly shows the login. I did apply the custom white screen boot mac logo, but it doesn't show the progress indicator which looks much cleaner and authentic on the standard black background.
