Latitude E7270: update to Monterey failure


Recommended Posts

Hello guys,

    I've been running macOS Big Sur 11.6.1 without any trouble on my Dell Latitude E7270 under OpenCore.

    I tried to update to Monterey going to App Store, searching for macOS Monterey and clicking "get". The 12 Gb download completes, then the installation window and when rebooting, the installation gets stuck on the screen you can see on the attached picture.

    I tried to attach my EFI folder, but given its size, I wasn't able to. So I uploaded it and you can download it on the following link: https://wetransfer.com/downloads/aefaf629821a0ac2862dc0a19d669db420211203152125/fa1b40d3a98c8abbec09538f8a03c5e220211203152200/fcc471

    Any help would be much appreciated.

Thank you @Jake Lo.
I downloaded your OC 0.7.4 EFI folder from the provided link, used the Config.plist meant for Intel WiFi, modified with my GenSMSBios info and since Alps v7 did not work, I went back to the Apple PS2 and Voodoo PS2 controllers.

The OS did update to Monterey this time, but as you can see on the screen capture, WiFi is off, and the switch for turning it on is disabled...


Any help would be very much appreciated.

Thanks in advance.

 Thank you @Jake Lo
I replaced the Airport...._BS kext with one for Monterey. Now I have WiFi, but the Bluetooth is turned off, and even when the switch can be moved right to the on position, it still does not work.



Any clues on this would be much appreciated.

Thanks in advance.
