Jan 22, 2012 Installing Mac OS X on PCs running AMD processors has always been a controversial process. While the process of installing Mac OS X on PCs with Intel processors has (more or less) been legitimized, Mac OS X does not offer any official support for AMD processors, so the only methods available to AMD Hackintoshes remain in a state of quasi-legitimacy.
Run MakeInstall as Admin from within the gibMacOS folder. Upon first run of the tool it will install the required dependancies to create your installer.

Now inside the gibMacOS directory navigate to macOS Downloads/publicrelease/*Version You Downloaded* and then hold Shift and right click on RecoveryHDMetaDMG.pkg and choose Copy as Path,
Now right Click on the CMD window to paste the path and press Enter.

Once finished it will install the OpenCore bootloader to the USB as default.
If you upgraded the RAM, remove the upgrade RAM and then put the original RAM the computer shipped with and test it. If it stops the KP's then it's the upgraded RAM that has failed. If it has a lifetime warranty contact the mfg. to get it replaced. If it does not have a lifetime warranty replace with only Crucial.com or www.macsales.com RAM. Why, iMacs are very sensitive to using quality RAM and both vendors sell high quality products at fair prices and provide excellent support.
If you find it's not the RAM, then I'd suspect a failing HD.
