Last stop: Tahoe RC on Lenovo ThinkStation P500

Specs:

MB Lenovo ThinkStation P500 CPU Intel Xeon E5-2690 v3 2.60 GHz 12 Cores - 24 Threads RAM 64 GB DDR4 2133( 2x32GB) ECC Registered GPU PowerColor AMD Radeon RX 6600 8GB SSD1 ADATA SU650 256GB (For macOS) SSD2 SILICON POWER Ace A55 512GB (For storage) Audio Realtek ALC662 v2 Ethernet Intel i218LM Bluetooth TP-Link UB400

Everything working, except bluetooth.

Quirks: - Enabled RestrictEvents with revpatch=sbvmm to get the update. - Used -lilubetaall. - WhateverGreen had to be disabled during installation, it caused kernel panics. It does in Recovery too. - USB mapping has to be modified due to changes in the USB stack, uses a new key for identifying USB ports (which can also be found in System Report -> USB).

Example:

Old: UsbConnector, port

New: usb-port-type, usb-port-number

The guide can be found online, I won't link it as I don't know if it is allowed. USBMap from CorpNewt can also be used to automate the process, but in my case, it didn't work (couldn't parse the plist for some odd reason).

• FileVault will be enabled by default. You will need to use apfs_aligned.efi from OCBinaryData and disable EnableJumpStart. Otherwise, your password for decrypting your drive will not be recognized.
• As you all already know, AppleALC doesn't currently work due to Apple removing AppleHDA. The only way to get on-board audio to work is by using VoodooHDA at the moment, which doesn't sound as great as AppleALC, but it does the job, will switch back once AppleALC is fixed.
• Bluetooth currently doesn't work. Might need more tweaking on my part, although on the latest Sequoia, I got it working without any issues.

So far, it's going pretty well. As this is the last version of macOS to be released for Intel, I'll do my absolute best to get it working at it's full potential and keep it updated as much as possible.

Thanks to everyone in the OpenCore team, kext developers and especially to the awesome community, it was a wild ride. Let's make it count until the last security update!
