      Hi Guys,
       
      I was finally able to get my Catalina installer to boot using by changing EC0 to EC 4543305f 45435f5f. Huge headache with this as it took me a good couple of days to fix the error. 
       
      The good news is I can make it to the installer but now the problem is now the Catalina installer gets stuck at 2 minutes with the error code showing disk25s1 is not convertible to APFS.
       
      My Troubleshooting Steps:
       
      - Tried another NVMe drive, with same results
      - Checked Samsung Magician for updates, no luck
      - Formatted the drives in Ubuntu, same exact installer error.
       
      For some reason the disks always show as "Writable: NO" 
       
      Hardware:
      - Asus Z390-E 
      - Intel i7 9700K
      - Samsung 970 Pro
      - 16GB Crucial 
      - Intel UHD Graphics
       
      Is there something wrong with my kexts or config? 
       
      Thank You!

      A few days ago I faced a problem - installed ocquirks and it somehow broke my prelinked kernel. System won't boot then, and I spent more than a day restoring from the netatalk  backup to copy working prelinked kernel directory from the backup to the s/l
      So, my question is - how to relink prelinked kernel without that? I found boot args -f UseKernelCache=No but it didn't work. I was able to boot to the recovery, if that can help.

      Hi, I'm receiving these two errors before the system automatically reboots.
      36:296 00:063 OCSMC: SmcReadValue Key 4D535463 Size 1 36:351 00:054 OCSMC: SmcReadValue Key 4D534163 Size 2  
      Using OpenCore 0.5.7, Mojave 10.14.6 installed successfully (from USB, but have not gone through OS setup ie. 'select your country' screen yet) but now selecting the Mojave drive in the boot picker results in the above error.
      Hardware is Gigabyte H77-DS3H, Core i7 3770 (Ivy Bridge), Radeon Sapphire RX 580 Pulse, 16GB DDR3 ram.
       
      I had a fully working 10.14.4 install running OC 0.5.6 prior to this.

      OpenCore log and config.plist (with SMBIOS serials etc removed) attached - any help greatly appreciated.
       
      Thank you.
