jinbo Posted January 29, 2020 Share Posted January 29, 2020 How are you today? Jake I have tried to install Catalina on my Optiplex 9020. I could install the Mojave but not Catalina. BIOS version is A25 and all settings are fine. And I used the bootpack from this link you posted. But I couldn't install for now. I attached screenshots. Thanks Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 29, 2020 Moderators Share Posted January 29, 2020 Can I assume you are using the Catalina bootpack? Connected directly to DisplayPort? No other graphics card installed? Install latest Clover? Update kexts? Lilu.kext + Whatevergreen.kext mainly https://github.com/vit9696/Lilu/releases https://github.com/vit9696/Lilu/blob/master/KnownPlugins.md Quote Link to comment Share on other sites More sharing options...
morpheousman Posted January 31, 2020 Share Posted January 31, 2020 Do you have the ECDV to EC patch in config and a current version of Clover? I upgraded my 9020 directly from Mojave to Catalina. The only change I made was the ECDV to EC patch in Clover Config file, and made sure kexts were updated. Quote Link to comment Share on other sites More sharing options...
