Quirks (ACPI, Booter, Kernel and UEFI) for Intel and AMD CPUs. Based on the information provided by Dortania's OpenCore Install Guide and my own research (for 11 the Gen and newer). Presented in neatly structured tables.
Also available in list form which is easier to read and maintain and contains newer data, such as Quirks for 11th and 12th Gen Intel Core CPUs.
💡 TIP: All of these Quirks combinations are included in OpenCore Auxiliary Tools as presets in the corresponding Quirks sections!
Legend:
- x = Quirk enabled
- ( ) = Quirk disabled, but enabled for certain CPUs/Chipsets/Mainboards (read annotations for quirk in question)
- (x) = Quirk enabled, but disabled for certain CPUs/Chipsets/Mainboards (read annotations for quirk in question)
- empty = Quirk disabled. And by disabled, I mean disabled and not leaving it as is!

°Enabled by fefault in sample.plist. This Quirk didn't exist at the time the OpenCore Install Guide was written, so it's unknown if it's a requirement. Most likely it's not.
