I got myself into a little mess with FileVault enabled in Tahoe Beta 2 on my HackMini8,1. FileVault would not accept my password. I booted into Tahoe Beta Recovery, but was unable to unlock and decrypt through "normal" mechanisms. I was able unlock and decrypt by booting into Tahoe Recovery as follows:
  1. Boot Tahoe Beta 2 Recovery
  2. Select Tahoe Beta Volume to recover
  3. Open Utilities > Terminal
  4. execute 'diskutil apfs listUsers [Tahoe Beta Volume] to view user UUIDs and note the UUID for 'Local Open Directory User' (where Tahoe Beta Volume is /dev/diskXsY)
  5. execute 'diskutil apfs decryptVolume [Tahoe Beta Volume] -user [UUID noted in step 4]
  6. when prompted for password, enter your user password for your Tahoe Beta Volume
The encrypted volume should start to decrypt. Monitor decryption progress with 'diskutil apfs list'

After decryption is complete ('diskutil apfs list' reports FileVault 'No' for your Tahoe Beta Volume), reboot. You should now be able to boot and login to your Tahoe Beta Volume without FileVault.
Thanks @deeveedee it also solved my FileVault problem I mentioned in the Sequoia thread.
Using your steps, I could decrypt both of my MBP11,2 volumes.
 
Does anyone have any ideas on how to restore the large, central brightness
and volume control display in the Tahoe?

I don't like the fact that the volume and brightness display
now appears in the top right corner.
 
Last Tuesday, I installed macOS 26 Tahoe @OCLP 2.4.0 on my 18.3 iMac.
It took a little longer than with other supported macOS versions, but Tahoe was finally ready to boot.

A quick check of the system settings showed that Bluetooth was fully functional, but there was no network. The lack of Wi-Fi was to be expected, but the fact that LAN didn't offer anything either was surprising.
So I opened the OCLP app to perform the post-install and experienced the next surprise:

A little online research did yield the Kernel_Debug_Kit_26.0_build_25A5279m.dmg ...

Kernel_Debug_Kit_26.0_build_25A5279m.png
..., but how to integrate it to OC 2.4.0 is a bit beyond my capabilities.

What would I need to do to at least establish LAN?

Also Audio doesn't work.

Related suggestions are welcome. :)

Can you send your config.plist? I'll try to turn on the wi-fi.

The appropriate KDK is pulled automatically by OCLP if OCLP supports the current macOS to be patched (contingent upon the KDK's availability from Apple). See here for my modified OCLP results where I simply changed OCLP's macOS constants for Tahoe compatibility.

To properly patch Tahoe, we'll need an OCLP modified for new frameworks in Tahoe.

I know that, but I remember a very similar situation when OCLP didn't download the correct KDK (some version of Sonoma?), but one was able to manually install it with the correct KDK.
I was hoping for a similar effect, but I don't remember how I did it back then.
 
I managed to get through the welcome from a clean install to a clean disk of the beta 2 system. Yes, it's true, the sound was removed. This is bad!

OCLP needs an active network connection to retrieve the KDK. If no network connection is available, then KDK would need to be manually installed.

The changes were dramatic—as if I hadn't patched an OCLP-supported macOS yet.
The boot process was more or less normal shortly before logging in—after logging in, there was no more graphics support/a white desktop, ...

WLAN-iMac18.3-01.jpg

... a different resolution (also on the OC-picker), and opening the Control Panel seemed like slow motion.

The Wi-Fi is enabled—the logo is shown in the top right.

Before I can even search for the network, the iMac freezes.
I've now switched to the iMac 18.2, hoping the freeze won't last too long. But it doesn't look good—it's probably a permanent freeze.
I tried several times - always the same, even on macOS Sequoia where WLAN was also missing.

This is how it should be so that I know exactly where the joints are. Now try this one.

Regarding AppleHDA. Laobamac on Github modded OCLP so that runs in macOS Tahoe and also re-installs AppleHDA in macOS Tahoe.


Requires Github Account to download!

Try at your own Risk! You probably should not use this, if your system requires GPU/iGPU patches!

Edit: Audio is working again afer paching. But as stated earlier: don't use if your system requires iGPU/GPU patches.

По поводу AppleHDA. Laobamac на Github модифицировал OCLP так, чтобы он работал в macOS Tahoe, а также переустановил AppleHDA в macOS Tahoe.

Installed it. After the reboot, the pink screen appears. The keyboard and mouse are working. But the screen is all yellow 🤣
