[Guide] El Capitan 10.11.X - Dell Optiplex 780 (760) 755 (790) (990) in Installation Guides Posted November 5, 2015 Not sure what I'm doing wrong. But this is the 2nd time I get a panic shortly after the Apple logo (see pic). I'm running Chris1111 app. Also, according to the instructions 5. When clover boot screen is visible, choose boot “Mac OS X from El Capitan USB Installer”. But on my clover boot screen it says Boot "Mac OS from INSTALLER" (see pic)... NOT “Mac OS X from El Capitan USB Installer” as the instructions say. I tried to rename the USB to El Capitan USB Installer with no luck. I "THINK" i might know what I did wrong. I copied the ENTIRE FOLDER "AMD Radeon HD 5450" from the Optiplex 780 (760) El Capitan Clover-v3 to the EFI/EFI/ACPI/Patched not just the File "DSDT.aml". Gonna try it again!
