Yosemite Budget Hackintosh - This archived blog post originally from Geek Dime (now offline) covers inexpensive compatible hardware as well as OS X Yosemite installation with the Clover EFI bootloader.
This video -- courtesy of Roche Technology -- diligently explains how to install OS X Yosemite (10.10) on an X99-based PC motherboard using Unibeast with the Chimera bootloader app. He discusses other motherboards and other installation methods, as well.
Here are some technical details to understand what this hint is talking about.First, a bootloader was not restored. Mac OS X has no boot loader in the traditional sense. What you are referring to is the boot code in the Master Boot Record of disk. The first sector of the GUID Partition Table (GPT) disk contains is a Master Boot Record (MBR). Traditionally, the MBR contained a bootloader that would start the system running. Mac OS X does not normally use this bootloader.Mac OS X normally uses EFI. The EFI bootloader location is stored in various NVRAM variables that indicate what file to load in order to boot the computer. EFI is much more advanced than older boot systems in that it includes the ability to mount and read file systems.However, the Macintosh also supports Boot Camp. In order to support Boot Camp the Macintosh will boot from the MBR as described above. The boot settings in NVRAM can be set so that the Macintosh will boot using the MBR instead of the normal EFI settings. This is what makes Boot Camp work. (This is an Mac extension that is not a part of EFI.)The Ubuntu installer changed the bootloader in the MBR and also set the system NVRAM variable to boot from the MBR. This made it so that your main disk would not show up.Resizing the partition causes Disk Utility to erase the MBR bootloader and return the system to using EFI. I would have to guess that opening the Startup Disk Preference Pane would have allowed you to switch back to OS X, although the Ubuntu loader still would have been present. You would see that in the Startup Disk Preference Pane as a selection to boot into Windows. :-)Just some fun technical knowledge to explain what is really happening.
So is there someway to manually erase the MBR bootloader and/or return the system to using EFI through a command console of some sort before entering the OS or through the terminal using the OS X boot disc? I am having the same problem as the OP, but I cannot see the primary partition in the disk utility using the boot disc, and I can't use the trick the OP used.
I go to File --> New, click "Install from disc or image," select the corresponding InstallMacOSX.dmg disk image file, selecting the specific OS version (I tried selecting the 32-bit and 64-bit versions in separate attempts since I'm not sure which the linked installer is) and both times when the instance reboots, it says it couldn't find a hard drive or CD-ROM drive ("No compatible bootloader found" for each one). VMware then opens a window saying "No operating system was found." I get the same error when trying Mac OS X 10.8 Mountain Lion, and I haven't yet tried other OS versions.
In order to install macOS on your Hackintosh hardware successfully, you must add the FakeSMC.kext kernel extension to the EFI partition that is created and mounted upon completing the install of the Clover EFI bootloader in Step 5. You should also copy AppleIntelE1000e.kext for Ethernet support.
Since the Clover bootloader is installed on the internal drive, and the required configuration values were changed, you should no longer have to select boot options to boot correctly into macOS. If everything worked, macOS will boot normally when choosing Hackintosh HD from the Clover Boot Manager.
Clover is an open-source EFI-based bootloader created on Apr 4, 2011. It has a totally different approach from Chameleon and Chimera. It can emulate the EFI portion present on real Macs and boot the OS from there instead of using the regular legacy BIOS approach used by Chameleon and Chimera. For many, Clover is considered the next-gen bootloader and soon it will become the only choice since BIOS in being replaced by UEFI in every new motherboard. One big feature of Clover is that iMessage, iCloud, the Mac App Store works along with Find My Mac, Back To My Mac and FileVault since Clover can use the EFI partition. (Read more)
Throughout the years, many "distros" were released for download over the Internet. These distros were copies of the Mac OS X installer disc modified to include additional components necessary to make the OS run on the non-Apple hardware. A prominent member of the community, JaS, released many distros of Mac OS X Tiger containing patched kernels. Some other popular distros are iATKOS, Kalyway, iPC and iDeneb. Distros have fallen out of favour as the OSx86 community grew, as new bootloaders were developed that made it possible to use actual copies of the OS X Installer.
After the initial release of OS X Yosemite 10.10 BETA, various developers took on the role of updating their bootloaders for the system. Members of OSx86 forum InsanelyMac set to update the EFI Bootloader Chameleon for this new OS release. Some time later, Niresh (an independent OSx86 developer) released a standalone tool known as Yosemite Zone, which would automatically install the new OS and other various features on a non-Apple device with minimal input. This method consisted of torrenting an OS X 10.10 DMG onto a USB flash drive with MacPwn Vanilla Installation. Unibeast was updated to support Yosemite,[25] and a distribution of Yosemite Zone was released with AMD processor support.A vanilla installation of Yosemite is possible via Insanelymac's Pandora Box Beta 2.0 and UniBeast. This type installation uses as few kexts (drivers) as possible in addition to using an unaltered version of the OS X installation app, and is preferred over distributions.[26][27][28]
Both Clover and Chameleon were updated to be compatible with El Capitan. Unibeast[29] and MacPwn[30] were updated to support El Capitan as well, since El Capitan, Unibeast (and Multibeast) use the Clover bootloader instead of Chimera (a Chameleon-based bootloader).
Clover r4945 was the first version of Clover to support macOS Catalina, beginning with the first developer beta of macOS Catalina 10.15.[42] UniBeast was updated for macOS Catalina support, but there has not yet been a MultiBeast release for Catalina.[43] For the first public stable release of macOS 10.15, AMD patches were also released, allowing the booting of macOS Catalina on AMD CPU systems.[44] A new bootloader began to emerge during this time, called OpenCore. It is a necessity for AMD users beyond macOS 10.15.2.[45][46]
The work started with EFI emulation in the form of David Elliot (dfe)'s modified version of Boot-132 called "Darwin/x86", which has a "FakeEFI" system that emulates EFI.[60] In early November 2007, a group of hackers (fronted by a Russian hacker known as Netkas), using Elliot's code, developed a method[61] of emulating an EFI environment using a specially modified Darwin bootloader.[62] In practical terms, this meant that regular PCs meeting a set of hardware requirements could now be "seen" as real Macintosh computers by the OS, allowing the use of unmodified, "stock" Apple kernels (as long as the CPU supports it) and thus giving more transparent and reliable operation. Several methods for real world deployment of this innovative solution have arisen around the Internet. An explanation of this achievement along with a usage guide was provided by the website DigitMemo.com.[63]
Boot-132 is a bootloader provided by Apple for loading the XNU kernel.[66] In mid-2008, a new modified BOOT-132 came on to the scene.[67] This method allows users to conduct the Leopard-based OSx86 installation using a stock, retail-purchased copy of Mac OS X Leopard and eradicates the necessity of a hacked installation like JaS or Kalyway (mentioned previously). The Boot-132 bootloader essentially preloads an environment on the system from which Leopard can boot and operate. The bootloader stores the necessary files (kext files) in a .img collection or simply a folder. The luxury of this new installation method includes the ability to boot and install from a retail Leopard DVD and update straight from Apple without breaking the DMCA. The only possible problem here is that it breaks the macOS EULA.[68]
The bootloader behaves like the Linux kernel: one can use an mboot-compatible (a patched syslinux was used for the hack) bootloader that tells boot-dfe about the .img file (the ramdisk or initrd, as it's known by Linux users), and boot-dfe will then use the kexts (or mkext) from it. This new boot-dfe has been tested with the retail Leopard DVD, and it can boot, install, run Leopard without having to build a modified DVD.
Since the early developer builds of Mac OS X v10.6, members of the OSx86 community had been booting the new operating system using yet another bootloader called PC EFI provided by Russian hacker Netkas or the bootloader of the Voodoo team's Chameleon. Chameleon is based on David Elliot's Boot-132. The bootloader supports ACPI, SMBIOS, graphics, ethernet, and some other injections. It allows to boot up macOS on non-Macintosh hardware. Chameleon supports a lot of AMD as well as Nvidia graphics cards. There are a lot of forks of it by different developers; the latest version upstream is 2.2 from 2014.[69] 2ff7e9595c
