My Latitude e7440 won't boot from an OpenCore installer USB stick. Here's what I've done: 1. I created the USB stick by formatting the entire USB device in macOS (Catalina) to be GUID Partition Map and Mac OS Extended (Journaled) file system. I used createinstallmedia to copy Catalina onto the USB drive. I also copied Jake Lo's OC 0.6.0 folder from the post below into the EFI partition (I used MountEFI to make the EFI partition visible in the Finder). 2. I plugged the USB drive into my Latitude E7440, and got to Boot Options. I set the USB drive to be first in the list, and used Hervé's list to configure the rest of my E7440 BIOS Settings. 3. Each time I boot, the USB drive is skipped/ignored, and the laptop boots from the internal drive. What should I investigate to make the computer boot OpenCore from the USB drive? PS I don't think it would matter, but I should note that the laptop has a previous macOS install based on Clover. Once I get OpenCore booting, my plan is to erase the entire internal drive and do a clean install of macOS Catalina ... Thanks!
Hello all! This is the guide I am following: https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-clover-guide/&do=findComment&comment=54632 I've been toying with this E5450 for a while now and have finally gotten some progress, turns out I was an idiot and didn't configure the Bios properly: (I missed this) 2. Press F2 to configure the BIOS Sata Operaton -> AHCI Secure Boot -> Disabled Boot List Option -> UEFI. Enable Legacy Option Rom Apply and Exit So now I am getting I'm getting past the initial loading but it bombs out with this kernel panic: Some notes: Boot pack - I used this one: Broadwell - (See Note2 below) E5450_HD5500.zip 418.94KB 442 downloads Updates: I followed note to check for updates and replaced this kext: E7x70, E7x50, E5450, Precision 7510 AppleHDA_ALC293.kext.zip 13.26KB 385 downloads Anyone have a red hot clue what I did wrong?
