#Mac os efi boot how to#

In the video above I demonstrate step-by-step how to build a computer that will work as a Hackintosh. Check this website to see what hardware is compatible with a Hackintosh. Many computer parts work for Hackintoshes. And in many places it is illegal to sell a Hackintosh. So don't plan on taking this into an Apple store for repair. It is not illegal to create a Hackintosh for personal use but it does go against Apple's End User License Agreement. In this written tutorial, you will learn how to create the macOS installer using macOS or Windows. The video shows how to use a computer with macOS to create a macOS installer for your Hackintosh.

I also created a video version that shows how to build a complete machine and then install macOS on it. This tutorial will focus mainly on how to install macOS on your hardware. Some people have been able to create a Hackintosh for under $100.

I created a Hackintosh computer that matches the Mac Pro specs for about 1/3rd the price of a Mac Pro.

The main benefit of a Hackintosh compared to an official Macintosh computer, is that it is WAY cheaper. You will learn how to install macOS Big Sur (or any other version of macOS) using OpenCore. In this tutorial, you will learn how to create a Hackintosh. Hence I would now like to get some more information on how this all fits together.A Hackintosh is a non-Mac computer system, made with PC parts, that runs the macOS operating system. scap files in a macOS installer, which appears to prove my theory. I then tried to repair the damage by copying my Mac's EFI partition to his Mac, using iBored (which I wrote myself, so I know what I was doing, trust me on that).Д«ut that did not help - the Mac would still not boot.ДЄfter a while I figured that his rather old Mac (a MacBook Pro early-2009) probably required a different EFI firmware than the other Mac from which we tried copying the EFI firmware.ДЄfter some digging I found the mentioned. Without this EFI partition, the Mac would not boot any more. Recently, a friend got his EFI boot partition overwritten, whereas his main Mac boot partition had remained intact.

I wonder if it still may contain additional support for Macs whose boot ROMs can't be updated, such as adding support to boot from APFS volumes, perhaps. Meaning there's no need to create a bootoable EFI partition at all. This suggests that neiter files need to be present at boot time at all, at least on recent Macs. This resulted in a new EFI folder being created in the EFI partition with the same Firmware.scap file. I also did a test where I renamed the top 'EFI' folder to 'EFI-OFF' and rebooted a MacBook Air 2015. So, if the particular Mac had already installed the particular file into its Flash ROM once, it won't be needed any more and can be removed from the EFI partition.

This answer suggests that the files in the FIRMWARE folder are not loaded when booting the system but are rather just used to flash the ROM.

Is EfiUpdaterApp2.efi needed to run the firmware, or is that only a leftover from an older firmware update process and can be removed?Д¬an I create a universal EFI boot partition, containing the firmware for any Mac model, so that I can put that onto an external disk and boot practically any Mac from it for which I've included its. fd file (which may be optional) then goes into the FIRMWARE folder?

scap file matching the Mac model and rename that to Firmware.scap, whereas a model-matching. Which files do I take from the macOS Installer, and where do I place them in the EFI volume? E.g, do I use the. The EFI partition requires particular values in the GPT.ДЄn EFI partition is a FAT32 volume with a folder structure like this: EFI How does one create a working EFI partition from those? called EFIPayloads) with EFI firmware files named MP61_0116_B17_LOCKED.scap, MBP114_0172_B09_LOCKED.fd or similarly.
