#Clover efi error loading kernel cache drivers#
At this point, enough drivers are loaded for the kernel to find the root device. Once the kernel and all drivers necessary for booting are loaded, the boot loader starts the kernel’s initialization procedure.

This process is very slow, because the ist file of every kernel extension must be parsed, and then the linker must be run.įor more information on how drivers are loaded, see IOKit Fundamentals, the manual page for kextcache, and Kernel Extension Programming Topics. On OS X v10.5 and v10.6, these caches are located in /System/Library/Caches//Startup/ on previous versions of OS X, it was located at /System/Library/Caches//.įinally, if the caches cannot be used, the boot loader searches /System/Library/Extensions for drivers and other kernel extensions whose OSBundleRequired property is set to a value appropriate to the type of boot (for example, local or network boot). Using the mkext cache is much slower because the linker must be run. If the prelinked kernel is missing or unusable (for example, because a hardware configuration has changed), the booter looks for the mkext cache, which contains all kernel extensions that may be needed to boot the system. This cache contains exactly the set of kernel extensions that were needed during the previous system startup, already linked against the kernel. In OS X v10.6 and earlier, the boot loader first looks for the prelinked kernel (also called the kernel cache). It is located at /System/Library/Caches//Startup/kernelcache.

This cache contains all kernel extensions that may be needed to boot a Mac with any hardware configuration, with the extensions already linked against the kernel. In OS X v10.7, the boot loader looks for the unified prelinked kernel. Important: You should not depend on the implementation details of the kernel caches in your software. In the simplest case, the boot loader can be found in the /System/Library/CoreServices directory on the root partition, in a file named boot.efi. (This UI is drawn by loginwindow otherwise.) If full-disk encryption is enabled, the boot loader is responsible for drawing the login UI and prompting for the user’s password, which needed to access the encrypted disk to boot from it. As it does this, the boot loader draws the “booting” image on the screen. The principal job of this boot loader is to load the kernel environment. Once BootROM is finished and an OS X partition has been selected, control passes to the boot.efi boot loader. The user can override this choice by holding down the Option key while the computer boots, which causes EFI to display a screen for choosing the boot volume. If multiple installations of OS X are available, BootROM chooses the one that was last selected by the Startup Disk System Preference. POST (Power-On Self Test) initializes some hardware interfaces and verifies that sufficient memory is available and in a good state.ĮFI does basic hardware initialization and selects which operating system to use. BootROM has two components to help it carry out these functions: BootROM (which is part of the computer’s hardware) has two primary responsibilities: it initializes system hardware and it selects an operating system to run. When the power to a Macintosh computer is turned on, the BootROM firmware is activated. this is my first post on this forum.Next Previous The Early Boot Process Boot ROM i would be Great help if you guys help me to figure out my problem i am uploading EFI folder which i am using right now for Sierra installation. and they are not accepting debit cards from india. as my id asking me to enter credit cards details which i don't have.

i have downloaded EL capitan and macOS sierra from puter i can't download from app store. this is my System configuration and some one suggested me to try with this clover configuration i tried with both EL capitan and macOS Sierra.
also tried replacing OsxAptioFixDrv-64.efi with OsxAptio2FixDrv-64.efi and by placing both. i tried Rebuilding prelinked kernel it didn't solved my problem. can anyone help me with it ? i tried with EFI downloaded from this forum also still i am getting same problem. i thing i made some mistake with my EFI configuration.
