Entropic Posted November 26, 2020 Share Posted November 26, 2020 Hi, I'm trying to install Big Sur on a Dell Latitude E5470 (i5-6300U, 8GB, Intel HD520 graphics) with that same Opencore EFI as posted here, but I get Kernel panic and reboot in the last installation reboot (I get to the installer, format disk and install, and reboot twice, but KP in last reboot with progress bar under apple about to finish). BIOS settings should be fine 'cause it worked properly with Catalina 10.15.7 (with Clover). Any ideas? Thanks in advance. Entropic. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 26, 2020 Moderators Share Posted November 26, 2020 If you're switching from Clover to OC, make sure you select "Reset NVRam" at the OC Picker. If you don't see it, the press the spacebar to review the option. Link to comment Share on other sites More sharing options...
Entropic Posted November 27, 2020 Author Share Posted November 27, 2020 Got the option "Reset NVRAM" at OC Picker and used it, but with no results. After reseting again NVRAM with USB stick, I repeated all the process, reached OS Installer, formatted the disk and began installing. In Final reboot, just at the end of progress bar, it rebooted and so on. Maybe I could try with Clover updating kexts, but is funny 'cause OC is working with that laptop and Big Sur for other people. Thanks all the same. Entropic. Link to comment Share on other sites More sharing options...
Entropic Posted November 27, 2020 Author Share Posted November 27, 2020 (edited) I forgot saying that my screen is a FHD 1080p one. I don't know if that point has something to do with kernel panic, but it could occur when changing graphics mode. Edited November 27, 2020 by Hervé typos...

Moderators Jake Lo Posted November 27, 2020 Moderators Share Posted November 27, 2020 try adding to boot arg to complete the install -igfxvesa Link to comment Share on other sites More sharing options...
Entropic Posted November 28, 2020 Author Share Posted November 28, 2020 Thanks for the suggestion, but i tried with no result. I added -Igfxvesa to config.plist with Open Core Configurator in NVRAM section, boot-args, right click>Boot args>Whatevergreen>Igfxvesa, as shown in the screen capture. I tried to boot with the new config with same results. After that, I tried a fresh install with that bootflag with same results. Do you know another EFI bootpack for Latitude E5470? I'm beggining to think there must me something different in my laptop to the one that this EFI was made for. Thanks for your attention.

Administrators Bronxteck Posted November 30, 2020 Administrators Share Posted November 30, 2020 maybe you are on a different bios version than what the boot pack was created for. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 30, 2020 Moderators Share Posted November 30, 2020 @Entropic what model is your drive? If it's NVMe, check to see that it's not Samsung PM981. It's known to not work properly in Hackintosh. Link to comment Share on other sites More sharing options...
Entropic Posted December 1, 2020 Author Share Posted December 1, 2020 It could be true. I updated BIOS to the last version, but Catalina worked without problem. Disk is a M2 Toshiba SATA. Not NVME. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 1, 2020 Moderators Share Posted December 1, 2020 give this a try, replace into /EFI/EFI E5470_OC063.zip Link to comment Share on other sites More sharing options...
