NetTech Posted November 15, 2019 Share Posted November 15, 2019 Hey everyone, I followed Herve's guide to installing Mojave/Catalina on a Latitude 7490 but am getting kernel panics every time I try the install. I managed to get past the hardware compatibility check, but now I am getting "EFIRuntime" as last loaded kext. I've searched and tried about 10 different solutions posted on forums but keep getting different panics. Any assistance out there? Latitude 7490 Core i7 vPro 8th gen 16GB ram EDIT: corrected a typo.

Administrators Bronxteck Posted November 15, 2019 Administrators Share Posted November 15, 2019 are you using 1 16gb stick of ram or 2 8gb having both ram slots populated? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 15, 2019 Moderators Share Posted November 15, 2019 Remove the DSDT.aml from /EFI/Clover/ACPI/Patched and try again If still fails, boot with boot arg -igfxvesa FYI, moving post, this is not a guide Link to comment Share on other sites More sharing options...

Removing DSDT.aml successfully got me to this screen (see below). Now the mouse is stuck in the top left corner. Apologies for creating this in the wrong spot, I'm new to the forum.

Moderators Jake Lo Posted November 15, 2019 Moderators Share Posted November 15, 2019 you need external mouse to complete installation, I think it's noted in the guide. Link to comment Share on other sites More sharing options...
NetTech Posted November 15, 2019 Author Share Posted November 15, 2019 Yessir it is, but for some reason my external USB mouse/keyboard is not working as well. I was able to get to this screen, but I can't use the keyboard to enter past it either. I can cycle through using Tab, but pressing Enter doesn't do anything.

NetTech Posted November 15, 2019 Author Share Posted November 15, 2019 Huge help, thanks! I was able to get into the Install screen. Now it's saying that my blank HDD has a newer version of MacOS. This is just after I did a complete erasing of the drive in question. The drive in question is a 500GB NVMe. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 15, 2019 Moderators Share Posted November 15, 2019 when formatting, make sure to enable view by devices and format the whole disk to GUID / Journal Extended. HS will auto convert it to APFS during install. What brand/model is your NVMe drive? Link to comment Share on other sites More sharing options...
NetTech Posted November 15, 2019 Author Share Posted November 15, 2019 Yessir I formatted the whole disk to Journal Extended, but the drive is still greyed out for me with that same error. The SSD is Toshiba part# KSG60ZMV512G Link to comment Share on other sites More sharing options...
