[SUCCESS/HELP] MSI B760 GAMING PLUS WIFI + i7-14700 + RX 580(2048SP Moded) [Tahoe Beta 6]

[sims]

Hello InsanelyMac community,

After an incredible run from 2013 to Last Week, I have finally retired my trusty old Hackintosh and built a new one. I'm creating this topic to share the success/help and details of my new machine, but first, I wanted to pay a small tribute to the build that served me faithfully for over 12 years.

A Long Journey: My Z77 Build (2013-2025)

 

This machine was my daily driver for more than a decade, taking me from OS X to macOS. It's a testament to how long a well-chosen Hackintosh can last.

• MB: MSI Z77A-G45 Thunderbolt

• CPU: Intel® Core™ i7-3770 (Ivy Bridge)

• Memory: Started with 8GB, later upgraded to 24GB DDR3

• Video: Initially used the integrated Intel HD 4000 graphics. To keep up with modern macOS, I later upgraded to a modded AMD Radeon RX 580 2048SP.

• Bootloader: Started with Clover for the early years and eventually migrated to OpenCore for the best compatibility with recent macOS versions.

• OS History: This machine ran everything from OS X 10.8.5 Mountain Lion all the way up to macOS Sonoma.

It was a fantastic and reliable machine. Now, onto the main event: my new build for 2025

    Questions & Areas for Improvement

     

    While the build is running very well, I'm hoping to solve the remaining issues and would appreciate any advice from the community on the following points:

  • Onboard Audio (ALC897): I'm using AppleALC.kext with alcid=11 12 66 98 99, but the onboard audio jacks are not working. Has anyone with this codec found a working layout-id or required device properties for macOS Tahoe?

  • Wi-Fi Stability (Intel AX211): The Wi-Fi works with itlwm.kext and Heliport but no ip adresses from dhcp, Are there specific settings?

  •  

  • Verifying CPU Performance (i7-14700): How can I best verify that macOS is managing my CPU correctly All 20 Core? i know that the name of cpu are not correct ( i can change it in the config.plist nvram ) I want to ensure it's idling at low frequencies and boosting properly under load. 
    
    Thank you for reading, and thanks in advance for any help you can provide!
