[pre-release] macOS Tahoe

[surenmunoo]

Anyone know why my machine enters sleep mode when I have it turned off. The monitor goes off and then the machine shutdown and comes back on, only way to get it going again is a reboot.

I can't help but express my gratitude and give due credit to: the OCLP Team, @LockDown, @Anto65, @Max.1974, and countless others who tested the app and offered their support thank you all!

 

Thanks to you lol, all the credit goes to you ( @LockDown it was definitely the icing on the cake 👏 )

 

Obrigado

I bet you look very pretty in an apron standing at the kitchen sink. 

Of course, you had doubts? 😅
But she decides which apron to wear...
I have to let her get away with something

@jsl I don't want to add another cook in the kitchen, but you should carefully inspect your config.plist.  

• 'remove revpatch' in NVRAM > Add > 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102' is not a valid property.  It should be 'revpatch'
• You are missing 'NVRAM > Delete > 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 > revpatch

 

Slow down, look carefully at the examples provided and you will succeed.

 

EDIT: Note that you need only

• NVRAM > Add > 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102 > revpatch: cpuname,sbvmm

and not the revpatch boot-arg.  Remove 'revpatch=cpuname,sbvmm' from boot-args. 

 

EDIT2: @jsl I performed a quick test to make sure my advice was sound.  Here are my config.plist modifications and the resulting "About This Mac"

Installing KDKs 

Also from Ventura to Tahoe!

It will also Revert the Snapshot

Also Backing Up KDKs

The program will be available in OpenSource on Github verry soon, iam verry exited about it

That´s amazing @chris1111 

 

Great, this will made things more easy in Tahoe.

It will only install kext´s or bundle + Framework too?

Yes, I think now we’re going to have a dedicated thread. I just need to fine-tune a few adjustments in MyKextInstaller and gather some testers you're on that list... LOL. Then I’ll open a dedicated thread for MyKextInstaller.

At your disposal, whenever you want, call us ... for science this and more 😆

basically if we still use 25A5279m KDK we dont need to copy AppleHDA.kext back to  SLE because with 

sudo ditto /Library/Developer/KDKs/KDK_26.0_25A5279m.kdk/System /System/Volumes/Update/mnt1/System

it will copy All the System Folder from KDK to destinated location 

 

please note that for system can't boot well with beta 1 will be affected, because with this kdk restore all the kext will be back to beta 1 kext .  because there is no new KDK yet for beta 2 and beta 3 .. CMIIW

 

Yeah, I realize that since I was using the DB1 (KDK_26.0_25A5279m) kdk (which already has DB1 AppleHDA.kext in its /S/L/E), its not necessary to copy the same AppleHDA from the desktop to the mounted root/S/L/E after merging with the ditto command.  

 

Like you said, it is preferable to use the kdk version which matches the macOS version you are patching for (in this case, I would have used DB3 KDK_26.0_ 25A5306g if it were available).  In this scenario, since this prospective DB3 kdk (and probably future ones) won't have AppleHDA in it, I was trying to illustrate a proof of concept in the method - copying over a stored, earlier DB1 AppleHDA.kext from the desktop, into the merged & mounted root/S/L/E (which wouldn't have an AppleHDA if using DB2 or DB3 kdks).

Good morning. My modified USB kext for Tahoe crashes the hack when he goes on standby... Any idea ?

I feel like I'm taking a trip back in time, when we used these procedures to install kexts on macOSX
Good old days...🙂

[hiphopboy]

Anybody knows how to using NTFS partition on this version ?

Not much to analyze. It might help if you post EFI (including your modified USB kext).

[deeveedee]

No issues with Hackintool 4.0.3 in Tahoe Beta 3, so it doesn't appear to be a Hackintool issue.  Using VoodooHDA.kext 3.0.2 in /Library/Extensions with csr-active-config = <01000000>.  My EFI is attached here.

 

[MacWill]

Stuck here. What could be going on? 😔

Thanks

[deeveedee]

@MacWill Without seeing your EFI, without knowing whether it's an upgrade or clean install, what version of macOS, CLOVER or Open Core and version, whether your EFI booted any previous versions of macOS, I'm going to go out on a limb and guess that it's a frayed power cord.  That said, I do appreciate your confidence in our mind-reading capabilities.

yes the method is correct, it used in OCLP root patch root patch  with kdk merge and kmutil

Großartig, das wird die Dinge in Tahoe einfacher machen.

Es werden nur Kexts oder auch Bundle + Framework installiert?

Wenn Sie Bundles auf diese Weise kopieren oder installieren können, wäre es dann auch möglich, die Bundle-Pakete für NVIDIA Kepler zu installieren, wie in meinem Bild gezeigt?

Es wäre toll, wenn die vollständige Grafikunterstützung wieder funktionieren würde.
