Here is documentation on installing the MacOS Monterey onto the Dell Latitude E6520.
I could not get the OpenCore Legacy Patcher to work. After applying the root patches, rebooting just goes so far along and then restarts.
Wireless card and Graphics fixes are thus not applied.
I got a Lenovo T420 to play with next.

I have also been trying to get Monterey up on my old E6520 for several days. Right now, I can get to the recovery page, but the installation does not proceed. It goes back to the recovery page.
You want to compare notes?
