[Pre Release] macOS Sequoia 15.4

Smooth upgrade of my HackMini8,1 from 15.4 Beta (24E5222f) to 15.4 Release Candidate.  This is the first time for me during 15.4 Beta testing that the OTA installer was not incremental.  On my hack, the upgrade from 15.4 Beta (24E5222f) to 15.4 Release candidate downloaded the full installer.  I'm not using OCLP on this hack (SIP is fully enabled and the APFS volume is sealed) and I disabled BluetoolFixup.kext before the upgrade.

 

 

After the upgrade, all appears to be good.

Sequoia 15.4 RC2 beta in NEW: perfect OCPL ERROR OpenCore Configurator 

 

[deeveedee]

Smooth upgrade of my HackMini8,1 from 15.4RC1 to 15.4RC2. Unlike RC1, my RC2 upgrade was incremental, so I haven't figured out the rhyme or reason of the full/incremental 15.4 Beta upgrades.  Using the exact same EFI as with the RC1 upgrade (and no OCLP, SIP fully enabled, APFS volume sealed, BluetoolFixup.kext disabled).  Booting with OC 1.0.4.

He he he we understood what you were referring to
what I don't understand is that CCC works for you in Sequoia 15.4 ... you will be the only one 😛 ... enlighten us

 

Hi my friend, I can open normally Opencore Configurator, maybe you should try use compile your Opencore and Kexts on System 

 

Clover configurator I have issues, but I opened normally too. I will check what's happen

OCC opens without any problems, but can you try changing SMBios and share the result? It crashes when I try to do this.

Best regards.

Hi @strangeron my friend, are you using Usbports.kext ? It's because the Usbports use SMBIOS on his config.plist inside the kext. 

How SMBIOS you want that I can try it for test? iMacPro1,1?  Thanks for your report 

I think that I installed Rosetta on my M4 Apple Silicon, and because that, I think its Clover Configurator opened normally. But I can test on my desktop change SMBIOS. 

 

EDIT: @strangeron yes, here crash too when I try change SMBIOS with Usbmap kext. I got error report too.

Look at my equipment and the wifi model works perfectly on both. The official version will be released today, we'll see what it says.

@surenmunoo Here works fine, maybe is OCLP release, or device properties, check your plist 

And i prefere use Clover, but OC 1.0.5 its ok too with OCAT.

I reverted back to @MaLd0n original EFI 1.0.3 and it works again. Must be something I did wrong when setting up the 1.0.5 EFI. Wifi works in Ventura though with new EFI.
