Nope, it isn't working for me. Oh and that problem persists even with Herve's EFI configuration.

Quick update on the current issue: Yes, the network issue is pretty much gone, and sleep seems to work (even with Microsoft Edge opened in the background, and as Edge is now Chromium-based, maybe Chrome won't affect sleep?). However, the headphone jack is dead after waking up. Any ideas on how to fix this?

Alright, I will try this out. Oh, and I just ordered a DW1510 (which should work with Big Sur IIRC), guess I'll have to wait a week before I can test that out

I just installed Big Sur on my Latitude E6530 (i5-3320M, 1366x768, HD4000) using this EFI config which was based on @Hervé's guide: https://github.com/sunabozu/dell-e6430-big-sur-opencore

So far it's doing pretty well, however, there are a few issues:

 - Sleep doesn't seem to work well, for short sleep periods it will work nicely, but longer periods and it will either freeze at some point after wake or just totally freeze during wake.

 - Sometimes network access after boot results in macOS beachballing, and getting stuck while trying to reboot.

 - Some USB ports (namely the back or the left USB3 port) would sometimes die and require a reboot (tried remapping the USB ports using Dortania's guide, but to no avail).

My attached EFI is based on the above EFI but with some changes:

 - Removed USBInjectAll.kext+FakePCIID*.kext and replaced with USBmap.kext

 - Regenerated SSDT-PM.kext for my i5-3320M

 - Removed TG80211 and replaced with HS80211Family.kext + AirPortAtheros40.kext for AR9462 (https://www.insanelymac.com/forum/files/file/1008-io80211family-modif/)

Is there anything that I can do to fix the issue? And yes, I've tried the original EFI by Herve (the #5 one to be exact), and it offers no improvements on the issue.
