elBuey Posted October 29, 2021 Share Posted October 29, 2021 Hello guys, I've used some Opencore EFI folders shared on this page for my Latitude 7490. I think I started with Big Sur 11.3 and managed to update it all the way to 11.6.1 I've recently tried to update to Monterey, and it didn't work. This is what happened: 1- I went to Apple Logo - About this Mac - Software Update 2- I clicked on update now, agreed to the terms and conditions, and confirmed the hard drive to install to. 3- The downloading begun and took some minutes (12 Gb download) 4- The laptop rebooted, and on the OpenCore menu I selected Macintosh HD. 5- The verbose begun and got stuck on the attached pictures for some seconds, after which the laptop rebooted and the same happened once and again if I chose "Macintosh HD" on the OC pickup. 6- After several tries on which I verified exactly the same happened over and over, on the OpenCore pickup I selected "macOS" and booted back to Big Sur. Doe anybody have a clue on what may be wrong? Thanks! Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 29, 2021 Administrators Share Posted October 29, 2021 A copy of the OpenCore EFI folder maybe? Which version of OpenCore? It's best to update to version v0.7.4 and adjust your config accordingly of course. Link to comment Share on other sites More sharing options...
idle Posted November 1, 2021 Share Posted November 1, 2021 In my case, updating the bootloader to 0.7.4 helped, also updated lilu, VirtualSMC, WhateverGreen, then I updated OpenCore Configurator to the latest version, opened my config.plist in it and just clicked save, only after that I was able to complete the update .. ...

FoUStep Posted November 1, 2021 Share Posted November 1, 2021 Mind sharing your EFI? About to update my 7390 (based on Hervé's 7490 Catalina build) with a fresh install of macOS Monterey. Building an USB (w/ OpenCore) with Monterey as we speak. Would be nice to have a decent example of a working EFI for Monterey based on 7490.

Jazzoo Posted November 1, 2021 Share Posted November 1, 2021 @idle +1 I will be thankful if you can share your EFI for test. I couldn't get mine working with Monterey. Working rock solid on Big Sur tho. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 1, 2021 Moderators Share Posted November 1, 2021 did you upgrade all the kext and OC to 0.7.4? Post your perfectly working EFI Link to comment Share on other sites More sharing options...
Jazzoo Posted November 1, 2021 Share Posted November 1, 2021 I was not able to upgrade the OC correctly. Here's my 100% working BigSur EFI (touchpad buttons included) Dell 7490 Big Sur 100% Working EFI.zip Link to comment Share on other sites More sharing options...

FoUStep Posted November 2, 2021 Share Posted November 2, 2021 Am I correct to assume this can also be used with an USB installer with Monterey and not just an installed macOS instance (just like with Clover)? Curious to try this when I get home. Hopefully @idle can post his working EFI for reference. Link to comment Share on other sites More sharing options...
Jazzoo Posted November 2, 2021 Share Posted November 2, 2021 @Jake Lo It's working! Just upgraded to Monterey on my test ssd. Would you provide the exact steps for OC update ? I tried replacing all files as per guide but no success. Link to comment Share on other sites More sharing options...
