Clover is a new and exciting open source EFI bootloader. Developed over the past 3 years by a group of developers at Project OS X led by Slice, Clover aims to solve problems inherent in existing OS X installation methods and legacy bootloaders:
- Boots troublesome desktop and laptop BIOS/UEFI
- Uses native OS X installation media
- Ability to patch DSDT/kernel/kexts at boot time
- Creates OS X Recovery partition
- No boot0 error with 4K Advanced Format drives
- Solves multi-boot issues with Linux and Windows 7/8
- Solves traditional bootloader NVRAM issues related to iMessage/FaceTime
Download the OS X Yosemite Application from the Mac App Store; Prepare a USB flash drive as Installer; Install OS X Yosemite; Install the bootloader and drivers to system drive; Download OS X Yosemite. The full operating system is a free download for anyone who has purchased Mac OS X Snow Leopard, Lion, or Mountain Lion. Download the relevant macOS or OS X installer from Apple, then use Terminal to create a USB installer you can boot up from. Or use the OS X installation disc that came with your machine — or buy a new one — to boot up and install OS X on your Mac's hard drive.
Clover has a completely different system of configuration with a decidedly steep learning curve. It can be confusing for those who have only ever used the more traditional Chameleon or Chimera.
Clover is also in beta stage, and is not guaranteed to work well for all systems. Development has been fast and furious, with many major changes appearing in the code all the time. Clover can be a moving target, difficult to pin down- almost, it seems, by design. Recent changes, however, have stabilized things enough to be a reliable alternative for those adventurous enough to learn something new.

Download OS X Yosemite
The full operating system is a free download for anyone who has purchased Mac OS X Snow Leopard, Lion, or Mountain Lion. Download the Application from the Mac App Store using your Apple ID on any Mac or functional computer running Mac OS X 10.6.8 or later.
- Open Mac App Store
- Log in with your Apple ID

1. Insert the USB drive
2. Open /Applications/Utilities/Disk Utility
3. Highlight the USB drive in left column
4. Click on the Partition tab
5. Click Current and choose 1 Partition
6. Click Options...
7. Choose GUID Partition Table
8. Under Name: type USB (You can rename it later)
9. Under Format: choose Mac OS Extended (Journaled)
10. Click Apply then Partition
11. Open /Applications/Utilities/Terminal
12. Type the following, enter password and hit enter. This command completely erases the USB, then creates native OS X installer media from the Install OS X Yosemite Application.

13. Download the latest version of Clover from Sourceforge
14. Open Clover package installer
15. Hit Continue, Continue, Change Install Location...
16. Choose the USB, now called Install OS X Yosemite
17. Hit Customize and install Clover to the same USB with the following Custom Install settings:
NOTE: There are a few different ways to setup Clover on the USB. Using Legacy Mode is the simplest and most reliable for 5, 6, 7, and 8 series Gigabyte motherboards with standard default BIOS or UEFI settings. For all other UEFI-based systems such as Asus 7 and 8 series motherboards, use UEFI Boot Mode to install to the EFI partition of the USB for UEFI booting only.
A few more changes need to be made to the default Clover installation:
20. Navigate to /EFI/CLOVER/ and replace default config.plist with attached config.plist*
21. Navigate to /EFI/CLOVER/kexts/ and create a folder called 10.10
22. Navigate to /EFI/CLOVER/kexts/10.10/ and add FakeSMC.kext
23. Navigate to /EFI/CLOVER/kexts/10.10/ and addyour ethernet kext
24. Navigate to /EFI/CLOVER/kexts/10.10/ and addNullCPUPowerManagement.kext
25. Navigate to /EFI/CLOVER/drivers64UEFI/ remove VBoxHfs-64.efi and add HFSPlus.efi
26. (Optional) Navigate to /EFI/CLOVER/ACPI/patched/ and add DSDT.aml and SSDT.aml
*See attached config.plist for a working minimal configuration.

Install the Bootloader and Drivers to System Driver
At this point, the easiest way to proceed is to install the bootloader, grab backups from the root of your USB drive, and copy the files that worked directly to the system drive's EFI partition. However, getting post-installation 100% right for your system is something that needs to be done on a case by case basis. No single Clover setup will work perfectly for every system. For best compatibility, it is recommended that the EFI partition also be reformatted to FAT32 instead of default HFS.
1. Open /Applications/Utilities/Terminal
2. Type: diskutil list and locate your system drive's EFI partition. It will be under IDENTIFIER. Be sure to use the correct one. (For this example: disk0s1)
3. Type the following, enter password and hit enter:
4. Download the latest version of Clover from sourceforge
5. Install Clover to Yosemite with the following Custom settings:
These settings will install the bootloader to the system drive's EFI partition automatically as part of the scripting. After completion, the system drive's EFI partition will automatically mount.
A few more changes need to be made to the default Clover installation:
6. Navigate to /Volumes/EFI/EFI/CLOVER/ and edit config.plist
7. Navigate to /Volumes/EFI/EFI/CLOVER/kexts/ and create a folder called 10.10
7. Navigate to /Volumes/EFI/EFI/CLOVER/kexts/10.10/ and add FakeSMC.kext
8. Navigate to /Volumes/EFI/EFI/CLOVER/kexts/10.10/ and add your ethernet kext
9. (Optional) Navigate to /Volumes/EFI/EFI/CLOVER/ACPI/patched/ and add DSDT.aml andSSDT.aml
See attached config.plist for a working minimal configuration. For more details and documentation navigate to /EFI/CLOVER/doc. To help navigate the config.plist and add a system definition, check outClover Configurator. For a GUI to mount/unmount EFI partition, see EFI Mounter v2.
