Extraction can therefore be done on Linux, OS X, Windows, or even in the Clover bootloader.

So, on any OS, you can extract them for patching later. The process of patching involves several steps:Īll BIOS implementations provide ACPI files to the OS. changing hardware or memory configuration If any of the following is changed, you must re-extract, re-patch, as these changes may cause significant changes to the native ACPI (especially SystemMemory regions): Keep in mind that even changes you make to your own system (BIOS, hardware, etc.) will require re-extract, re-patch. It is also not uncommon for the same laptop model to be produced in different runs with different motherboards, and potentially incompatible ACPI files. Such differences can make various OperationRegion addresses different, which makes a patched DSDT for one system incompatible with another. Even minor differences in hardware configuration (BIOS version, amount of memory installed, BIOS options selected, and other hardware differences such as which WiFi card is installed) can make for differences that cause instability and weird bugs if you use foreign ACPI files. You simply cannot be certain it is valid to use ACPI files from another computer. See guide here: Īlthough you may be tempted to use a DSDT from another computer, it will almost always end in failure. The purpose of this guide is to provide a foundation for proper patching of your OEM DSDT/SSDTs.Īdvanced users may wish to implement hotpatching via Clover. In order to make many OS X features work well on a laptop, you will always need a properly patched DSDT (and maybe some of the SSDTs).
