If you want to have a dedicated topic for your app you can always create a dedicated topic and post whatever you want that's relevant to your topic, like the latest updates, a link to download the last version a change log, etc. but going off-topic about anything rather than the original topic is only tolerable to a certain point.

 

@Cyberdevs

Hi

You've got the wrong enemy.
Did I start the debate on the topic "Full DownLoad"?
So if the URL for Full DownLoad Tahoe 25A354 is off-topic, I'll delete this post and the others.
To Anto65, I apologize for polluting the thread he started.
To you Cyberdevs, from now on, I will submit the content of my posts to you before publishing them, you who seem to confuse moderation with censorship.
Do we need to remind you, as Famtomas did recently, that you begin a post with "hi" and end it with "best regards"?

Are you fixated on me?

 

Best regards

 

PS: Forgive me if this is off topic.

Was offered the OTA delta update to Tahoe_25A354 on my Skylake NUCi5SYH (after reverting system to the last sealed snapshot) but then decided to perform an upgrade install using the full installer app for a change 😜....

As with the RC post update, I manually root patched Tahoe_25A354 with B1 AppleHDA and the latest KDK_26.0_25A353.kdk from Apple Developer/Dortania downloads to restore the Realtek ALC283 audio through headphones and DP audio through my monitor's attached speakers...

First of all my initial post wasn't directed at you, but you seem to take everything personally.
Secondly no one here is my enemy, or anywhere else, not that I know of. If you think you and I are enemies you are mistaking big time.

Oh boy! on the contraire, you seem to confuse the meaning of words, I'm just doing my job and I don't have to explain myself to you or anyone else. and trust me there is no need to send me anything if we deem fit we can have your contents be moderated before being publicly available so don't bother sending me your post or whatever.

I don't need you to teach me life lessons, and by "we" who are talking about? is there an anti-cyberdevs fan clubs that I don't know about?

It is possible. Download and run the full version Tahoe 26.0 (25A354).

Thanks. I got message : Not compatible with this Mac . I use SMBIOS iMac19,1 + no_compat_check in boot-args, it was working with the beta.  It concerns the Desktop from the signature.

First thanks everyone for your hard work sharing your experience and suggests for Tahoe.

Now it happens that I could successufully update to 26.0 (25A354) but i lost usb.

I used the same usb pen I used till now for Taohe but now it doesn't recognize my usb ports and the few  that appear work badly so I'm forced to use old wired mouse and keyboard.

Audio is ok thanks to oclp mod.

Where am I failing? Did I miss something in your huge posts about this matter?

Thanks for help.

 

Fixed thanks to @MaLd0n and his efi for XantraX.

Hello All,
is OCLP-Mod able to install modern wireless patches to Tahoe?

No, most popular devices are not supported yet. But after the OCLP patch, you can use @chris1111 driver for some USB Wi-Fi adapters

https://github.com/chris1111/Wireless-USB-Big-Sur-Adapter

At the time of writing this message, support is only available in macOS Tahoe RC (build 353) and Tahoe 26.0 (build 354)

Fast and flawless incremental OTA upgrade from Tahoe RC -> Tahoe Release AFTER disabling Beta Updates (System Settings > General > Software Update > Beta Updates: Off).  With Beta Updates enabled, the first Tahoe release did not appear as an OTA Upgrade option.  

 

I'm still using VoodooHDA (since Tahoe Beta 2), so I have not had to touch audio since Tahoe Beta 2 and SIP csr-active-config remains as <01000000>.  I am not using Wi-Fi on this hack, so I'm not applying any post-install patches.  All working very well.

 

Screenshot2025-09-16at8_20_44AM.png.40f7cfe3f75e6d7321e76e218089c0ce.png

 

My steps to upgrade from Tahoe RC -> Tahoe Release were as follows:

  1. Boot macOS Tahoe RC with BluetoolFixup.kext disabled and boot-arg -wegnoegpu
  2. Change Software Update > Beta Updates from On -> Off
  3. Allow Software Update to detect and perform incremental OTA upgrade to Tahoe Release
  4. Enable BluetoolFixup.kext and remove boot-arg -wegnoegpu

 

EDIT: Interesting note... on my HackMini8,1 with only UHD630 iGPU (no dGPU), Tahoe Release upgrade was available with Beta Updates enabled.  Of three hacks that I have upgraded, two required Beta Updates disabled and one did not.  Not sure why.

has nothing to do with xattr

In my case nothing of all this seems to be the issue or case. Not an issue of gatekeeper, nor that the app would be quarantined. The OCLP-Mod root patch is simply not applied.

@KGP-iMacPro Just curious - why do you continue to post OCLP-Mod questions in threads other than the OCLP-Mod thread?

 

In my initial post about success with Thaoe 25A354 here, I just mentioned problems with OCLP-MOD as a subordinate clause in parallel with Whatevergreen. By this like always startet a discussion about a possible solution here. Sorry for that. Let's move over to the OCLP-Mod thread with this.

config.plist 19.07 kB · 4 downloads

Try with the Booter/Patch in the attached plist. With NVRam Reset.

Thanks. Gives same result as boot-arg. I had to restore SMBIOS iMac20,1 for install. Install in progress,  I will see later when installed if iMac20,1 is still required.

Edit:

MacOS 26 Release installed.

I can boot normally with iMac19,1 and -no_compat_check

Smooth update on my main drive and the testing drive.  Disabled Bluetooth and rolled back the OCLP patches for the install.  Things are still a bit slow despite OCLP-mod installed.  Hopefully that will iron out with future updates.  Overall very pleased with the results.  BTW audio is working.

 

Cheers, Howard

How to disable FileVault:

 

1.) 

https://www.insanelymac.com/forum/topic/361162-pre-release-macos-tahoe/page/63/#findComment-2834848

 

2.) less complicated if you have a dual boot system with another macOS 😉

Tnx man but I think I jumped too soon :).

I guess it runs in the background so you don even see the process unless you use a terminal command to monitor the process.

@mnfesq, this is a temporary limitation. By the end of the year, the corresponding patches will be developed. And now, if this is a critical issue, you can use a cheap USB adapter. In this thread there is a list of devices compatible with Tahoe (via OCLP)

Hi all folks! I think I got it right, with the patch updater it wasn’t necessary to disable SIP and it didn’t enable FileVault!!

Now it seems that CLT is more stable with Xcode 26 ;) 

 

:avião:

Hello!

 

I tried to use TP-Link T2U Nano with Tahoe, but it doesn't work.

What I have tried so far:

- Installed the lastest KDK

- Used OCLP-mod for USB patches

- Installed chris1111's big_sur driver

 

The adapter works on Sequoia, but not in Tahoe. Any ideas why would be highly appreciated!

 

Thanks!
