As Clover is a OpenSource project, everyone who wants

to compile may compile...

To make the things a lot easier, STLVNUB made a script

that makes all the hard work for you, this way you can

have Clover always at the latest revision without the need

to wait till someone publish a new package and also, make

your own changes to the code if needed...

You will need to have Xcode and Command Line Tools in order

to use the script...

Additional tools to compile Clover will be automatically

installed by the script.

Download and run the installer...


Press continue and when you reach the customisation section, change the install location if needed then press "Customize"…


Read carefully the instructions given for each option after you select a entry at the bottom of the window, if you don't understand exactly which option you should choose, you can use the options selected at the image below…


Click "Install", write your password, wait till the installation finishes and reboot...


If you installed Clover using "boot1f32alt", you own the ability to have and use more than one bootloader on the same disk...

boot1f32alt gives to you 2 seconds to press the number of your desired boot file and choose the Bootloader that you want to use...

For example, assuming that you installed 64bit Clover as default option, you can use the 32bit one by pressing "3", or if you rename Chameleon's "boot" file to "boot1", if you press "1" you can use Chameleon as Bootloader...

There's also the possibility to have XPC and Revoboot, for detailed instructions take look here > One Fat32 Usb Stick With Many Hackintosh Bootloaders/managers - Project OS X Forums Thanks to dmazar for this awesome tip!

Clover main goal is EFI booting...

If you plan to use Clover, keep in mind that Legacy boot (non EFI boot) may work or not, so,

maybe you can't boot your current Windows or Linux Installations through Clover...

In this case, you can use the "tip" at Installation section and have the ability to use Chameleon

to boot your "Legacy" OS and have all Clover's benefits to boot OS X...

This does not mean that in the future this will not be completely fixed...


For those having issues with Legacy Boot (non UEFI boot) using the default option...


You can try using the option below...
