While we've already previously discussed how to use boot flags on the Chameleon and Chimera bootloaders, which were formally the two most popular bootloaders for PCs running Mac OS X, the release of OS X El Capitan has now shifted attention onto the new and upcoming Clover bootloader. All Hackintosh installation methods for El Capitan, including tonymacx86's ever-popular Unibeast method, now use Clover. Unfortunately, using boot flags on Clover requires a slightly different technique than on Chameleon/Chimera (although most of the boot flags themselves remain the same). That's what this guide is here for.
How to use temporary boot flags on Clover
On Chameleon/Chimera, you could enter a temporary boot flag by simply typing it directly into your computer's bootloader menu. In contrast, the process is slightly more involved with Clover.
To enter a temporary boot flag into Clover, first start your computer and wait until you reach the Clover bootloader menu, which will look something like this (aka the Unibeast menu, assuming you installed OS X that way):
NOTE: There are technically two different options buttons-- one is for "Clover Options", while the other is just "Options." You want to choose "Options."
If you need help finding the right boot flags for your Hackintosh, check out our list of common boot flags (this list is tailored for Chameleon/Chimera, but Clover supports many of the same flags).
How to use permanent boot flags on Clover
Once you've managed to boot into your Hackintosh, you'll probably want to make those boot flags permanent, so that they'll automatically be entered into the bootloader every time you start Mac OS X. This process is also a bit more involved in Clover, compared to Chameleon/Chimera.
Traditionally, you could permanently enable certain boot flags by adding them to the text file "org.Chameleon.boot.plist," which was essentially the settings file for Chameleon/Chimera. Clover's settings rely on a similar text file called "config.plist."
DOWNLOAD: Clover Configurator
Once you've downloaded it, open up the Clover Configurator app (which comes in a ZIP file). The home page of the app will display some number of seemingly identical files named "config.plist," with the exact number depending on how many hard drives your computer has.
Your actual "config.plist" file will be on your computer's EFI partition. To modify it, you first have to mount the EFI partition, which is usually hidden when you boot OS X.
To do this, click on the "Mount EFI" button on the left column. Then, in the page that comes up, click "Mount EFI partition." If you have multiple hard drives, choose the hard drive that OS X is currently booting from. In the screenshot below, Clover Configurator tells me that I'm currently booting from disk0s2, so I choose disk0s1 (because it's part of "disk0").
