floflo19 Posted April 23, 2020 Share Posted April 23, 2020 Hi, I'm trying to do a fresh install of catalina with opencore. But I can't go to the installer, opencore doesn't start. This is my pc specs: dell 3521 : i3-3217u / hd4000 4gb ram / 480gb ssd / audio : alc282 Can someone tell me what I am doing wrong ? Thanks EFI.zip Link to comment https://www.insanelymac.com/forum/topic/343551-ivybridge-laptop-opencore-catalina/ Share on other sites More sharing options...
Donw35 Posted April 24, 2020 Share Posted April 24, 2020 I looked at your EFI, you need to go to this site and redo your folder... https://dortania.github.io/OpenCore-Desktop-Guide/ktext.html You may need additional files for your laptop so make sure to review this sections Link to comment https://www.insanelymac.com/forum/topic/343551-ivybridge-laptop-opencore-catalina/#findComment-2719008 Share on other sites More sharing options...

(I don't know why) So I installed catalina ( audio, wifi, ethernet, graphics, and usb devices working) I am now trying to get native powermanagement following this guide https://dortania.github.io/OpenCore-Desktop-Guide/post-install/pm.html#sandy-and-ivy-bridge-power-management I get a cpu warning in ssdtPRgen. And when I put the generated ssdt file, It won't boot anymore. Any advice ?
