For a Sandy Bridge Laptop, this section requires no modification and will remain untouched.
Quirks
The required Quirks for a Sandy Bridge Laptop includes:
| Options | Value | Notes |
|---|
| IgnoreInvalidFlexRatio | YES |
- Some types of firmware (such as APTIO IV) may contain invalid values in the MSR_FLEX_RATIO (0x194) MSR register. These values may cause macOS boot failures on Intel platforms.
- This quirk is required for Sandy Bridge based Laptops.
|
| ReleaseUsbOwnership | YES |
- Attempt to detach USB controller ownership from the firmware driver. While most types of firmware manage to do that properly, or at least have an option for this, some do not. As a result, the operating system may freeze upon boot.
- It's recommended to enable this quirk.
|
| RequestBootVarRooting | YES |
- Redirects AptioMemoryFix from EFI_GLOBAL_VARIABLE_GUID to OC_VENDOR_VARIABLE_GUID.
- This quirk is required for using the Startup Disk preference pane in firmwares that is not compatible with macOS boot entries.
- It's recommended to enable this quirk on all systems.
|
| UnblockFsConnect | NO |
- Some types of firmware block partition handles by opening them in By Driver mode, resulting in being unable to install File System protocols.
- If you're using an HP Motherboard, you'll need to enable this quirk.
|
| DuplicateBootOrder | YES |
- Remove duplicate entries in BootOrder variable in EFI_GLOBAL_VARIABLE_GUID.
- This quirk fixes duplicate boot order in Boot Menu.

Note:
The values which have been not discussed above, that will remain disabled.
