Released Sep 26th, 2023 as announced.
Version 14.0, build 23A344 (same as RC2 published Sep 21st).
Sonoma drops official support for Kaby Lake platforms that remained supported in Ventura, Apple raising minimal requirements to Amber Lake and Coffee Lake platforms (with the exception of iMacPro1,1 as in Ventura). However, support for Kaby Lake graphics remain provided with all KBL kexts still present, this in order to ensure support for Amber Lake MacBook Air8,1. By extension, this means that graphics support for Skylake iGPUs can also be retained using those same KBL settings as used in Ventura. For other iGPUs, patches are available through OCLP tool to regain graphics acceleration.
Officially supported Intel platforms are now limited to :
iMac19,x (8th gen. Coffee Lake)
iMacPro1,1 (Skylake Xeon)
MacBookAir8,1 (8th gen. Amber Lake)
MacBookPro15,x (8th gen. Coffee Lake)
Macmini8,1 (8th gen Coffee Lake)
MacPro7,1 (Cacade Lake)
With Sonoma, Apple also dropped official support for what they call "legacy" Broadcom cards that remained supported up to Ventura. These include cards based on Broadcom BCM4350, BCM4360 or BCM43602 chipsets. If Bluetooth remains natively supported on such legacy cards, native Wifi support is now limited to those Apple proprietary Broadcom SOCs that have been fitted to the above Mac models. Support for "legacy" Broadcom cards can however be recovered with specific patching using OpenCore bootloader, kexts blocking and OCLP patches.
Officially supported Broadcom SOCs include:
BCM4355 (802.11ac): pci14e4,43dc (iMacPro1,1 + MacBookAir8,x)
BCM4364 (802.11ac): pci14e4,4464 (Mac mini8,1 + MacBookPro15,x + MacBookPro16,x + iMac19,x + iMac20,x + MacPro7,1)
BCM4377b (802.11ac): pci14e4,4488 (MacBookAir9,1)
BCM4378 (802.11ax): Apple Silicon Mac models
BCM4387 (802.11ax): Apple Silicon Mac models
BCM4388 (802.11ax): Apple Silicon Mac models
NB: macOS Big Sur is now officially unsupported.
