OC 0.7.8 boot error

[jwballan]

I'm trying to move from Clover Bootloader to OC.  Following Dortania's 0.7.8 guide I built the config.plist and added require ACPI/Drivers/Kext file.  When I booted the usb it failed with:

 

35:800 00:030 AAPL: [EB|`LD:OFS] Err(0xE) @ OPEN (System\\Library\\PrelinkedKernels\\immutablekernel.x86legacyap.im4m)
35:830 00:029 AAPL: [EB|`SB:VK] Err(0xE) @ LD:LF
35:860 00:030 AAPL: [EB|`LD:LKCFFP] Err(0x1A) @ SB:SBVK
35:892 00:032 AAPL: [EB|#WL|7] 0x01 0x41   6 0x0E
35:921 00:029 AAPL: [EB|#REBOOT] 1
35:952 00:030 AAPL: [EB|#LOG:RESET:RECOVERY] 2022-07-13T14:11:28

 

I searched the web and found

 I also read Dortania's troubleshooting on the issue.  I set the various variables as suggested with the same issue.

 

I tried to follow the directions in Stuck on [EB|LD:OFS] Err(0xE) when booting preboot volume

but they don't work as describe;  The Mount mounts Preboot not the disk sector and it is /Volume not /volume

the diskutil apfs seems to run but it doesn' affect the results.

 

I'm trying to boot into Catalina and I've attached a zip of the necessary OC files and the error log.

 

Any suggestion?

 

Thanks in advance

@jwballan Kext Order is wrong. Framebufferpatch was missing "framebuffpatch-enable" property. Try this: OC-0.8.2.7z

[jwballan]

Thanks, I'll give it a try.

Reset to Recovery generally means that it is an issue with (Apple) secure boot. Disable SecureBootModel or choose a SecireBootModel other than Default. Default for the SMBIOS you've chosen is x86Legacy, which secure boot was only introduced for in Big Sur and newer. For Big Sur and older, secure boot model and choose SMBIOS don't need to match if you choose to keep apple secure boot enabled.

OK, I tried the OC you provided and it boot to the bootable icons, selected my boot sector and it rebooted

to the Recover volume.

 

The last several lines of the boot log are:

06:022 03:135 AAPL: [EB|#SB:HW] x86legacyap\0
06:072 00:050 AAPL: [EB|#SB:MF] (System\\Library\\PrelinkedKernels\\immutablekernel.x86legacyap.im4m)

06:318 00:041 AAPL: [EB|#LOG:RESET:RECOVERY] 2022-07-15T12:20:52
 

and the full log is attached.

 

The framebuffer values are the same as the ones in an earlier version of OC that boots,

although framebuffer-patch-enable is not present (not sure if that is a add option in

a later version than the one that boots.

1Revenger1  If I'm reading you post correctly, since I'm currently on 10.15.7 Catalina, I need to set SecureBootModel to Disabled.

Will this also resolve the ERR @ open issue or hopefully only the boot into recovery?

[Avery B]

The ERR @ as far as I know isn't an error which stops booting. I don't know what it means.

 

Secure boot model doesn't have to be disabled (though you could do that). You can specify another model - you would have to check the Configuration.pdf for other values though.

[jwballan]

Disable SecureBootModel  allows the system to boot, as of now the wireless is not working.

 

Thanks for all help.
