EFI Z490 Vision G OC 1.0.5 v3.0

Changelog

2025-06-14: Added early macOS Tahoe Support

macOS Tahoe is already a major pain…

• Updated OpenCore to version 1.0.5 (Nightly)
• Updated Drivers and Kexts
• Created a seperate Config for running macOS 26 (I had to)
• ACPI/Add: Recreated SSDTs
• Booter/MMIOWhitelist: Re-Created MMIO Whitelist
• Booter/Quirks: Enabled FixupAppleEfiImages
• Created additional config.plist for macOS Tahoe. Divergent settings:
  • Disabled GPU (Polaris)
  • Disabled Headless iGPU Framebuffer Patch
  • Enabled iGPU for display output
  • Disabled a bunch of kexts

Caution

1. macOS Tahoe does not like Polaris GPUs (RX5xx). In this case the iGPU has to be used to install and boot it. Otherwise you will be trapped in a loop. Maybe this can be addressed by future WEG update down the line.
2. Set iGPU in BIOS to enabled!
3. If you want to install/run macOS Tahoe, rename config_Tahoe.plist to config.plist
4. If you want to run macOS Sequoia or older, rename config_Default.plist to config.plist.
5. I225-V NIC does not work in Tahoe as of now. I use a PCIe LAN card (see specs for details)
