MorgenLadimoer Posted March 3 Share Posted March 3 (edited) System Specs: CPU: Intel Core i5-10400F (Comet Lake) Motherboard: Gigabyte Z590 Aorus Elite AX (Bios: VT-d Disabled) GPU: AMD Radeon RX 570 (Polaris) RAM: [Your RAM size, e.g., 16GB/32GB] Storage: Multi-drive setup (NVMe + multiple SATA HDDs/SSDs) Current OS: macOS 15 Sequoia (Running stable on iMac19,1) Target OS: macOS 16 Tahoe (Developer Preview) OpenCore Configuration: Version: OpenCore 1.0.6 (also tried latest Dev Build 1.0.7) SMBIOS: iMac20,1 (also tried MacPro7,1) Boot-args: -v debug=0x100 revpatch=sbvmm,cpuname,asset -radvesa (Removed amfi and cpus=1 for testing) What I have tried (ACPI & Patches): SSDTs: SSDT-HPET.aml, SSDT-RTCAWAC.aml (generated via SSDTTime), SSDT-PLUG, SSDT-EC-USBX. ACPI Patches: Applied 5 IRQ patches (HPET, IPIC, RTC, TIMR) and Gigabyte-specific RTC _STA fix. Kernel Quirks: ProvideCurrentCpuInfo: Enabled (for 10th Gen on 500 series chipset). DisableIoMapper & DisableIoMapperMapping: Enabled. XhciPortLimit: Disabled. DeviceProperties (SATA Injection): PciRoot(0x0)/Pci(0x17,0x0) -> device-id: 82A10000, compatible: pci8086,a182 (to spoof 400 series AHCI). The Problem: The boot process consistently hangs at: [AHCI][HBA] start:: 268: AppleAHCI::start Followed by a Kernel Panic or instant reboot. Before the hang, I see: Waiting on <dict ID="0">...<key>IOProviderClass</key><string ID="1">IOResources</string>...<key>IOResourceMatch</key><string ID="4">boot-uuid-media</string></dict> Notes: "I have verified that the issue persists even after updating to the latest OpenCore Dev Build and applying custom SSDT-HPET / RTCAWAC patches." I am currently testing with all other internal SATA/NVMe drives still connected. I am wondering if Tahoe has a more aggressive bus scanning mechanism that causes this panic on 500 series boards when mixed with 10th Gen CPUs, or if my SATA spoofing is no longer effective in macOS 16. Does anyone with similar hardware (Comet Lake on Z590) have success with Tahoe? Are there any specific Kexts or Kernel Patches required for the new AHCI stack? Any advice would be greatly appreciated! New Progress Installation successful! And attached my EFI folder Edited March 8 by MorgenLadimoer Quote Link to comment https://www.insanelymac.com/forum/topic/362470-%E3%80%90resolved%E3%80%91stuck-at-appleahcistart-on-macos-16-tahoe-i5-10400f-gigabyte-z590-aorus-elite/ Share on other sites More sharing options...

deeveedee Posted March 6 Share Posted March 6 @MorgenLadimoer Did you modify your USB port map for Tahoe? If you don't figure it out, please post your EFI (at least your config.plist, ACPI and Kexts folders). 1 Quote Link to comment https://www.insanelymac.com/forum/topic/362470-%E3%80%90resolved%E3%80%91stuck-at-appleahcistart-on-macos-16-tahoe-i5-10400f-gigabyte-z590-aorus-elite/#findComment-2847961 Share on other sites More sharing options...

Max.1974 Posted March 7 Share Posted March 7 (edited) Maybe you should try removing all the kexts that aren’t essential for booting. Like the samurai said in The Last Samurai: “Too many mind.” 😀 You not add boot arg npci=0x3000 Get Json file form Opcore Simplify see: https://github.com/lzhoang2801/OpCore-Simplify And some .efi files are not in the correct folders. The correctly is : Need refresh your config plist (OC Clean Snapshot) os use OCAT Edited March 7 by Max.1974 2 1 Quote Link to comment https://www.insanelymac.com/forum/topic/362470-%E3%80%90resolved%E3%80%91stuck-at-appleahcistart-on-macos-16-tahoe-i5-10400f-gigabyte-z590-aorus-elite/#findComment-2847994 Share on other sites More sharing options...
