MAHDIANO Posted April 18, 2020 Share Posted April 18, 2020 I followed all steps in this 7490 guide but it stuck in booting to OS to setup. It seems Catalina is missing settings, all links are broken. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 18, 2020 Moderators Share Posted April 18, 2020 Remove the DSDT.aml as your BIOS version might be different. 1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 18, 2020 Administrators Share Posted April 18, 2020 Just to be sure, you're following the Catalina guide for Catalina, right? Because your initial link pointed to the Mojave guide. Would I be right to assume that you're installing Catalina 10.15.4? I might need to revisit Catalina's installation guide given that there were many issues with the 10.15.4 update. Will try a fresh 10.15.4's installation on the 7490 to see... 2 Link to comment Share on other sites More sharing options...
MAHDIANO Posted April 20, 2020 Author Share Posted April 20, 2020 That fixed it, thanks a lot @Jake Lo @Hervé, is there any updated DSDT.aml for Catalina? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 20, 2020 Moderators Share Posted April 20, 2020 The DSDT is not related to the MacOS version, it's related to version of BIOS and BIOS configuration and must be patched using your Native exported DSDT. As stated, the DSDT main / only patch is for the Brightness control. Try this, replace Config file and add SSDT* to /E/C/ACPI/Patched 7490_BrightnessFnKeys.zip 1 Link to comment Share on other sites More sharing options...

remk90 Posted May 12, 2020 Share Posted May 12, 2020 Hello guys, I would like to share my trouble. I try to install Catalina (last version 10.15.4) on my 7490 (i5 version) I followed the guide from Hervé ( tu es Français ?) but I had the same problem than Mahdiano (I was not able to boot to Setup the OS after the second reboot). So I removed the DSDT.aml file as Jake Lo suggested and then I added the 7490_BrightnessFnKeys package. Now the installation is going farest but I'm not able to boot the MacOs I had the following message about GFX ( IMG_4007.jpg) Then i have a KP ( IMG_4006.jpg) Could you please help me ? I have no more ideas now.. Thx Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 12, 2020 Administrators Share Posted May 12, 2020 What version of Clover are you using? What version of Catalina are you installing? If 10.15.4, make sure you use at least Clover r5107 and, as stated in the 10.15.4 news update, you may have to boot with -disableigfxfirmware boot parameter until your installation has fully completed.
