| Step | Description | Typical Time |
|------|-------------|--------------|
| 1. Gather a legal macOS installer | Download macOS Big Sur 11.2.2 from the App Store (or use softwareupdate --fetch-full-installer). | 15 min |
| 2. Prepare a USB drive | 16 GB or larger, formatted as Mac OS Extended (Journaled) with a GUID Partition Table. | 5 min |
| 3. Apply the Olarila RAW EFI | Mount the USB installer, copy the EFI folder from the Olarila RAW release onto the USB’s EFI partition (replace the default OpenCore if present). | 5 min |
| 4. Edit config.plist | Use ProperTree or OpenCore Configurator to set:
• PlatformInfo > Generic > SystemProductName (e.g., iMac20,1)
• CPU power management patches (if needed)
• GPU framebuffer IDs (for Nvidia/AMD) | 10–30 min (depends on hardware) |
| 5. BIOS/UEFI tweaks | Disable Secure Boot, enable XHCI Hand‑off, set SATA mode to AHCI, turn off Fast Boot & VT‑d (if you’re not using GPU passthrough). | 5 min |
| 6. Boot from USB | Select the USB in the boot menu; OpenCore should appear, then choose “Install macOS Big Sur”. | 5 min |
| 7. Post‑install | After macOS boots, install the same EFI folder onto your system disk (or keep booting from the USB for a “portable” system). Run Hackintool or OCValidate to confirm everything is green. | 15–45 min |
Overall, a first‑time install on a well‑supported motherboard (e.g., ASUS Z390, Gigabyte B460) can be done in ≈1‑1.5 hours. More exotic hardware (e.g., older Skylake boards, obscure Wi‑Fi cards) may require additional kexts and ACPI patches, extending the time to 2‑3 hours or more. olarila big sur 112raw download link
Once mounted, download an OpenCore EFI for your chipset from the Olarila "EFI Folders" section. Delete the old OC folder and paste the new one. | Step | Description | Typical Time |
| Area | Highlights |
|------|------------|
| Stability | On hardware that matches the “tested list” (Intel 8‑/9‑gen CPUs, Intel UHD 630 or AMD Radeon Vega 8/10), the system runs smoothly, with no daily kernel panics. |
| Performance | Benchmarks (Geekbench 5, Cinebench R23) are within 5‑10 % of a real Mac with comparable CPU/GPU. Integrated graphics perform well for everyday use, and many users report near‑native performance in games that use Metal. |
| Audio/Video | AppleALC and Lilu provide functional HDMI/DisplayPort audio on most motherboards. The built‑in AppleHDA replacement works for most Realtek ALC codecs. |
| Wi‑Fi/Bluetooth | If you have a supported Broadcom or Intel Wi‑Fi card (e.g., BCM94360, AX200), the native macOS drivers work out‑of‑the‑box. For other cards, community‑maintained kexts (e.g., AirportBrcmFixup) often bridge the gap. |
| Ease of updates | Because the EFI is relatively generic, you can upgrade to later macOS releases (Monterey, Ventura) by swapping the macOS installer and updating a few kexts, without rebuilding the entire EFI from scratch. |
| Documentation | Olarila’s README and the Discord “#big‑sur‑112raw” channel contain step‑by‑step guides, a hardware compatibility list, and a “known‑issues” table that is regularly updated. | Once mounted, download an OpenCore EFI for your
Once you have the Olarila_BigSur_112raw.raw file (likely compressed as .7z or .rar), follow these steps.
